IMPORTANT INFORMATION FOR MEDTRONIC REUSABLE INSTRUMENTS AND REUSABLE TRANSPORTATION/STERILIZATION CASSETTES DESCRIPTION Reusable instruments are manufactured from a variety of materials commonly used in orthopedic procedures, which meet applicable national and/or international standards. These instruments may be shipped in Medtronic Transportation/Sterilization Cassettes. The Medtronic Transportation/Sterilization Cassettes are designed to be used in conjunction with a legally marketed and/or appropriate sterilization wrap, to allow steam sterilization of non-sterile devices. Medtronic aluminum Transportation/Sterilization Cassettes include cases, trays, lids, caddies, modules, or brackets fabricated from a variety of materials, which meet national and international standards, and are commonly used to enclose, protect, and organize Medtronic orthopedic or neurological non-sterile devices.
INTENDED USE Orthopedic surgical instruments are intended for use in surgical procedures to manipulate tissue, bone, or for use with other devices in orthopedic surgery. An instrument may incorporate a measuring function, which has uses as described on the label and the instrument. Note: do not implant the instruments. The Medtronic Transportation/Sterilization Cassettes are intended for use in healthcare facilities to organize, enclose, sterilize, transport, and store medical devices and other instrumentation between surgical and other medical uses. The Medtronic Transportation/Sterilization Cassettes are not intended on their own to maintain sterility; they are intended to be used in conjunction with a legally marketed and/or appropriate sterilization wrap. Medtronic does not warrant the use of the instruments, Medtronic Transportation/Sterilization Cassettes, or any of the component parts upon which repairs have been made or attempted, except as performed by Medtronic or an authorized Medtronic repair representative. Implied warranties of merchantability and fitness for a particular purpose or use are specifically excluded. Caution: these instructions do not apply to single use devices. For non-sterile, single use instruments refer to the Medtronic nonreusable and non-sterile instruments IFU, M708348B359.
WARNINGS ▪ Breakage, slippage, misuse, or mishandling of instruments, such as on sharp edges, may cause injury to the patient, or surgical or reprocessing personnel.
▪ Improper maintenance, handling, or inadequate cleaning procedures can render the instrument unsuitable for its intended purpose and may present a danger to the patient, or surgical or reprocessing personnel.
▪ There are additional risks associated with instruments used for bending and cutting rods. Use of these types of instruments can cause injury to the patient by virtue of the extremely high forces required. Do not cut rods in situ. Any breakage of an instrument or the implant in this situation could be extremely hazardous. The physical characteristics required for many instruments do not permit them to be manufactured from implantable materials, and if any broken fragments of instruments remain in the body of a patient, there could be allergic or infectious consequences. ▪ The surgeon should use extreme caution when working in close proximity to vital organs, nerves or vessels. In addition, excessive force should not be used when positioning instruments or implants, since it could cause injury to the patient. ▪ Breakage, slippage, misuse, or mishandling of Medtronic Transportation/Sterilization Cassettes, such as on sharp edges, may cause injury to the patient or operative and reprocessing personnel. ▪ Improper maintenance, handling, or poor cleaning procedures can render Medtronic Transportation/Sterilization Cassettes unsuitable for their intended purpose, or can even be dangerous to the patient or surgical staff.
▪ Correct handling of the Medtronic Transportation/Sterilization Cassettes is extremely important. Do not modify Medtronic
Transportation/Sterilization Cassettes. Do not notch or bend Medtronic Transportation/Sterilization Cassettes. Notches, scratches, or other damage and/or wear in Medtronic Transportation/Sterilization Cassettes occurring during surgery may contribute to breakage.
PRECAUTIONS ▪ Excessive force applied by instruments to implants can dislodge devices, particularly hooks. ▪ Instruments should not be exposed to temperatures in excess of 135°C (275°F). This level of heating may modify the
physical characteristics. If uncertain if the instruments were exposed to temperatures in excess of 135°C (275°F), carefully inspect the instruments to ensure they still function as intended. ▪ Extreme care should be taken to ensure instruments remain in good working order. During the procedure, the proper functioning of these instruments is extremely important. Instruments should not be bent or damaged. Misuse of instruments, corrosion, “freezing-up”, scratching, loosening, bending, or fracture of any or all components of the instrument may inhibit or prevent proper function. ▪ Do not use these instruments for any action for which they were not intended. ▪ Regularly review the operational state of all instruments and, if necessary, contact Medtronic or an authorized Medtronic repair representative. To avoid injury, the instrument should be carefully examined for functionality or damage prior to use. A damaged instrument should not be used. Additional back-up instruments should be available. ▪ Preoperative and operating procedures, including knowledge of surgical techniques, are important considerations in the successful use of the instruments by the surgeon. The proper selection and the compliance of the patient will greatly affect the results. ▪ Proper patient selection and operative care are critical to the success of the surgery and avoidance of injury during surgery. Read and follow all other product information supplied by the manufacturer of the implants or the instruments. ▪ Extra care should be taken when using instruments in pediatric patients, since these patients can be more susceptible to the stresses required in the use of the instruments. ▪ Ensure instruments with a measuring function are not worn and any surface engravings are clearly visible. ▪ Exposing Medtronic Transportation/Sterilization Cassettes to temperatures in excess of 135°C (275°F) may modify the physical characteristics. If Medtronic Transportation/Sterilization Cassettes are exposed to temperature exceeding 135°C (275°F), perform an additional inspection to ensure they function as intended. See the EXAMINATION section for more information. ▪ Extreme care should be taken to ensure the Medtronic Transportation/Sterilization Cassettes remain in good working order. During the procedure, proper use of Medtronic Transportation/Sterilization Cassettes is extremely important. Medtronic Transportation/Sterilization Cassettes should not be bent or damaged in any way. Misuse of Medtronic Transportation/ Sterilization Cassettes, resulting in corrosion, scratching, loosening, bending, or fracture of any or all sections may inhibit or prevent proper function. ▪ Medtronic Transportation/Sterilization Cassettes are subjected to repeated stresses related to routine transportation, cleaning, and sterilization processes. Medtronic Transportation/Sterilization Cassettes should be carefully inspected before each use to ensure they are fully functional. ▪ Medtronic Transportation/Sterilization Cassettes are not to exceed a maximum weight and load distribution of 11.4kg/25lbs. ▪ Personnel should wear all appropriate Personal Protective Equipment (PPE) as recommended by sterilizer manufacturer. ▪ Dissimilar metals should be separated from direct contact during sterilization to resist corrosion. Medtronic Transportation/ Sterilization Cassettes are designed with coated brackets or silicone to prevent contact of stainless steel instruments used in the Medtronic Transportation/Sterilization Cassettes.
POSSIBLE ADVERSE EFFECTS ▪ Nerve damage, paralysis, pain, or damage to soft tissue, visceral organs, or joints. ▪ Infection, if instruments or Medtronic Transportation/Sterilization Cassettes are not properly cleaned and sterilized. ▪ Pain, discomfort, or abnormal sensations resulting from the presence of the device. ▪ Nerve damage due to surgical trauma. ▪ Dural leak in cases of excessive load application. ▪ Impingement of close vessels, nerves, and organs by slippage or misplacement of the instrument. ▪ Damage due to spontaneous release of clamping devices or spring mechanisms of certain instruments. ▪ Cutting of skin or gloves of surgical or reprocessing personnel. ▪ Bony fracture in cases of deformed spine or weak bone. ▪ Tissue damage to the patient, physical injury to surgical personnel, and/or increased operating time that may result from the accidental disassembly of multi-component instruments occurring during surgery.
▪ The methods of use are determined by the user’s experience and training in surgical procedures. A successful result is not
always achieved in every surgical case. This fact is especially true in spinal surgery where other patient conditions may compromise the results. Physician note: although the physician is the learned intermediary between the company and patient, the important medical information given in this document should be conveyed to the patient. These devices should be used only by physicians familiar with the devices, their intended use, any additional instrumentation, and any available surgical techniques. In addition, these devices should be used only by operators familiar with the device, its intended use, and reprocessing information.

REPROCESSING - GENERAL CONSIDERATIONS Cleaning is the removal of organic soil. Effective cleaning: ▪ Avoids organic soil transfer from one patient to another. ▪ Allows for successful follow up sterilization. Adequate reprocessing is contingent upon the thoroughness of cleaning. Cleaning is the initial step. Sterilization occurs later in reprocessing and is intended to kill microorganisms to reduce the likelihood of transmission and possibility of infection. To ensure acceptable reprocessing, there should be no delay between the steps in this document. Instruments may be safely and effectively processed using manual or a combination of manual and automated washerdisinfector (enzymatic or alkaline) cleaning procedures outlined in this document. Medtronic Transportation/Sterilization Cassettes may be safely and effectively processed using manual or a combination of manual and automated washer- disinfector (enzymatic) cleaning procedures outlined in this document. The processor should comply with local laws and ordinances in countries where processing requirements are more stringent than those detailed in this document.
Bloodborne Pathogens Universal precautions for handling this instrument after use should be observed by all hospital personnel according to OSHA Standard 29 CFR 1910.1030 regarding occupational exposure to bloodborne pathogens.
Cleaning Agents and Cleaning Tools Instruments: The use of neutral detergents, enzymatic cleaners (7.0 – 8.0 pH), alkaline cleaning agents (8.0 – 11.0 pH), soft bristled brushes, and soft pipe cleaners are recommended. High alkaline cleaning agents (>11.0 pH) should not be used. Note: alkaline cleaning agents may require neutralization following cleaning. Refer to manufacturer’s instructions to determine if neutralization is required, and to follow manufacturer’s instructions for neutralization. It is critical that alkaline cleaning solutions be properly neutralized and rinsed from instruments. Aluminum Transportation/Sterilization Cassettes: the use of neutral detergents, enzymatic cleaners (7.0 – 8.0 pH) soft bristled brushes and soft pipe cleaners are recommended. Do not use alkaline cleaning agents as the alkaline cleaners will cause significant damage and render to the aluminum Transportation/Sterilization Cassettes unusable. The following cleaning agents, solutions, or tools should not be used on the instruments or Medtronic Transportation/ Sterilization Cassettes: ▪ Saline solution. ▪ Solutions containing chlorine (e.g. bleach) or aldehydes (e.g. glutaraldehyde). ▪ Formalin, mercury, chlorides, bromides, iodides, or Ringer's solution. ▪ Metal brushes or scouring pads.
Cleaning and Rinsing Water If available, softened tap water should be used. Critical water should be used for the final rinse step to prevent mineral deposits on surfaces (de-ionized water is recommended). One or more of the following processes may be used to treat water defined as critical water: ultra-filter (UF), reverse osmosis (RO), de-ionized (DI), or equivalent. Use of hard water should be avoided.
Use of Mineral Oil or Silicone-Based Lubricants Mineral Oil- or silicone-based lubricants should not be used as they may not be removed by these cleaning instructions. These types of lubricants may coat microorganisms, prevent direct contact of steam with instrument surfaces, and hinder sterilization.
Reprocessing Warnings/Cautions ▪ Do not allow soiled instruments or Medtronic Transportation/Sterilization Cassettes to dry after use and prior to cleaning.
Cleaning and subsequent sterilization may be hindered when blood or bloody solutions are allowed to dry on instruments or Medtronic Transportation/Sterilization Cassettes. ▪ Medtronic reusable instruments are considered critical devices (i.e. critical contact) and must be thoroughly cleaned, then sterilized prior to initial use, or in adherence to these reprocessing instructions before reuse. ▪ Soiled or used instruments should not be loaded into the Medtronic Transportation/Sterilization Cassettes for cleaning in an automated washer-disinfector. Soiled instruments must be processed separately from Medtronic Transportation/Sterilization Cassettes. ▪ Aluminum Medtronic Transportation/Sterilization Cassettes can only be cleaned utilizing enzymatic (neutral) cleaning solutions. ▪ Certain solutions, (i.e. alkaline based and/or containing bleach, glutaraldehyde or formalin) may significantly damage the Aluminum Transportation/Sterilization Cassettes. These solutions must not be used. ▪ Universal precautions should be observed by all health care facility personnel that work with contaminated or potentially contaminated instruments or Medtronic Transportation/Sterilization Cassettes. Caution should be exercised when handling instruments with sharp points or cutting edges. ▪ Appropriate PPE should be worn when handling or working with contaminated or potentially contaminated materials, devices and equipment. PPE includes gowns, masks, goggles, face shields, gloves, and shoe covers. ▪ Do not place heavy instruments on top of delicate instruments. ▪ Cool drafts from air ducts or other air currents should be avoided during the cooling phase to avoid post-sterilization moisture caused by rapid cooling.
Limitations on Reprocessing ▪ Repeated processing has minimal effect on these instruments or Medtronic Transportation/Sterilization Cassettes. ▪ End of life is determined by excessive wear and damage from normal use. Although the treatment of the instrument or
Medtronic Transportation/Sterilization Cassettes, materials used, and details of cleaning and sterilization have an important effect, for all practical purposes, there is no limit to the number of times instruments and Medtronic Transportation/ Sterilization Cassettes can be reprocessed. ▪ See the EXAMINATION section of this document to determine if the device is at the end of its useful life.

Follow the sterilizer manufacturer’s recommended procedures to program the sterilizer with any one of the sets of sterilization cycle parameters in Table 4. Table 4: Sterilization cycle parameters Cycle Temperature Exposure time Minimum dry time3 Dynamic-air-removal 132°C (270°F) 4 Minutes 30 Minutes (4 pre-conditioning pulses) Dynamic-air-removal 135°C (275°F) 3 Minutes 30 Minutes (4 pre-conditioning pulses) Dynamic-air-removal 134°C (273°F) 4 Minutes 30 Minutes (4 pre-conditioning pulses) Dynamic-air-removal 134°C (273°F) 20 Minutes 30 Minutes (4 pre-conditioning pulses) 3The minimum dry times were validated using sterilizers having vacuum drying capabilities. Drying cycles
Additional information
using ambient atmospheric pressure may require longer dry times. Refer to the sterilizer manufacturer’s recommendations. Chamber size and chamber load differences may exist between industrial and health care facility sterilizer models. The sterilization parameters listed in Table 4 can be achieved in both health care facility and larger, industrial sterilizer models. Because of the many variables involved in sterilization, each health care facility should calibrate and verify the sterilization process (e.g. temperatures, times) used for their equipment. Note: steam for sterilization should be generated from water treated to remove total dissolved solids and non-condensable gases, filtered to remove contaminates and water droplets, and supplied via piping without dead legs or other stagnant zones where contamination may collect. Caution: ethylene oxide (EO), gas plasma, gamma irradiation, chemical vapor, or dry heat sterilization methods are not recommended for sterilization of these devices. Steam/moist heat is the recommended method of sterilization. Immediately clean and re-sterilize all instruments used in surgery. Instruments should be thoroughly cleaned, inspected, and sterilized before being returned to Medtronic. Any medical device that has been in contact with a patient known to have or suspected to have a prion or prion-related disease, such as Creutzfeldt - Jakob disease, should not be returned to Medtronic and should be quarantined and processed per the guidelines for processing devices contaminated with high risk tissue at the health care facility. Contact Medtronic for information regarding proper disposal/destruction.
The cleaning and sterilization information provided is in accordance with AAMI TIR12, AAMI TIR30, ANSI/AAMI ST81, ISO 17664, ISO 17665, ISO 15883-2, and ISO 15883-5. The reprocessing instructions provided in this document have been validated as being capable of preparing instruments for reuse. The sterilization validation demonstrated a sterility assurance level of 10-6. The sterilization parameters were performed with Medtronic Transportation/Sterilization Cassettes. The sterilization validation was conducted using an empty chamber load. A double wrapped, “worst case” perforated tray configuration was used in the validation activities. It remains the responsibility of the processor to ensure the processing is performed using validated equipment and trained personnel in the reprocessing facility in order to achieve the desired results. This normally requires validation and routine monitoring of the process. Any deviation by the processor from the instructions provided should be properly evaluated for effectiveness and potential adverse consequences. Some devices have specific disassembly/re-assembly instructions. In this case, refer to the instructions provided with the instrument for additional instructions. Users must establish appropriate reprocessing protocols for reusable medical devices used at their sites using the recommendations of the device manufacturer and cleaning agent manufacturer.
STORAGE AND SHELF LIFE For non-sterile instruments and Medtronic Transportation/Sterilization Cassettes: store in dry, clean conditions at ambient room temperature. Non-sterile instruments and Medtronic Transportation/Sterilization Cassettes are reusable and do not have a specified shelf life. End of life (shelf life) is determined by excessive wear and damage from normal use. Refer to the Limitations of Reprocessing section for more information. For sterilized instruments and Medtronic Transportation/Sterilization Cassettes: ensure the instruments and Medtronic Transportation/Sterilization Cassettes are dry before storing. Store in clean, dry conditions at ambient room temperature. Shelflife of sterilized instruments and Medtronic Transportation/Sterilization Cassettes are dependent upon the legally marketed sterilization wrap. The health care facility should establish a shelf life for sterilized instrumentation based upon the type of sterilization wrap used and the recommendations of the sterile wrap manufacturer.
