General Warnings and Safety Notices - Read This First CW4 Arthroscopy Pump User’s Guide

1.0 General Warnings and Safety Notices - Read This First It is imperative that the symbols and conventions listed below be clearly understood. The CW4 Arthroscopy Pump User’s Guide identifies critical, important, and useful information using these symbols and conventions.

1.1

Important Safety Conventions Users of this device are encouraged to contact their Arthrex representative if they require a more comprehensive surgical technique.

W A R N I N G ! WARNING! is the most important safety symbol. It identifies critical information that must be followed precisely to avoid injury or death. 1. All fluid inflow devices, including gravity assist, may cause fluid extravasations into the surrounding tissues. This extravasation may be mild, moderate or severe. In severe cases, the resulting edema may result in a serious adverse patient event which may include compartment syndrome, nerve compromise, or death. Undiagnosed capsular defects will exacerbate fluid extravasation conditions. 2. When utilizing any fluid management device, the patient (extremity and surrounding area) must be monitored closely by the surgical team for signs of excess fluid buildup. Fluid usage volumes should be monitored and compared to similar surgical procedures. With all arthroscopy pumps, correct setup and proper user operation is required. Always select the lowest possible pressures in order to achieve the required intra-articular distention. All alarms or alerts must be acknowledged and the appropriate troubleshooting procedure followed. 3. Failure to follow the setup instructions and/or continuing to use the pump without resolving an alarm condition could result in a serious patient adverse event. 4. Failure to adhere to the setup instructions and use of Arthrex certified tubing may result in inaccurate pressure sensing and monitoring by the device. It is imperative that the user is aware that patient safety may be compromised when an alarm on the pump is ignored or silenced incorrectly. NEVER ignore or silence alarms. Follow appropriate troubleshooting procedures and carefully monitor the patient. Only Arthrex certified tubing must be used 5. This device is only for use in normal arthroscopic procedures as described in the User’s Guide, under the supervision of a trained and licensed physician. This device should not be used by untrained personnel or used for indications other than those described in this User’s Guide. 6. No modification of the console (AR-6485) or accessories is allowed. DFU-0249-5r0_fmt_en-US

General Warnings and Safety Notices - Read This First CW4 Arthroscopy Pump User’s Guide 7. DO NOT open or attempt to service this system, as this may void your warranty. There are no user-serviceable parts inside. Removing the cover may introduce an electric shock hazard by exposing you to dangerously high voltages or other risks. If the system malfunctions, return it for servicing immediately. 8. To avoid the RISK of electric shock, this equipment must only be connected to a MAINS POWER SUPPLY with a protective earth terminal. 9. DO NOT have the device in direct contact with the patient if high-frequency devices are in use, or if the patient requires defibrillation. 10. To ensure that correct pressure monitoring occurs, the pump and operative site MUST be in the same horizontal plane. 11. DO NOT stack or place equipment adjacent to the AR-6485 console, if possible. If such a configuration is necessary, carefully observe the configuration in question to ensure that electromagnetic interference does not degrade performance. 12. USE ONLY Arthrex approved accessories. Other accessories may result in increased emissions or decreased immunity of the system. Contact your Arthrex representative for a complete list of accessories. DO NOT modify any accessory. Failure to comply may result in injury to the patient and/or operating room staff. 13. DO NOT use in the presence of flammable anesthetics or oxidizing gases such as nitrous oxide, oxygen, or endogenous gases. All oxygen connections must be leak free for the duration of the surgical procedure. 14. Use ONLY Arthrex approved tubing accessories. Other accessories may result in decreased pressure accuracy. Contact your Arthrex representative for a complete list of accessories. DO NOT modify any accessory. Failure to comply may result in patient and/or operating room staff injury. 15. The extension and/or patient tubing must be replaced before each new patient and/or procedure. 16. The sterile connector cap must be used to cover the pump tubing set connector after each surgical procedure. This maintains sterility of the pump tubing and ensures its safe operation throughout the entire surgical day. 17. If the tubing is disconnected from the pump, it MUST be replaced. Do not attempt to reconnect the tubing to the pump as it could lead to unreliable pressure. 18. The safety and effectiveness of the AR-6485 is verified and documented; however, the AR-6485 must be used with an awareness of the risk of extra-

DFU-0249-5r0_fmt_en-US

Page 2 of 50

General Warnings and Safety Notices - Read This First CW4 Arthroscopy Pump User’s Guide articular edemas for patients with pathologically-changed articular capsules and for procedures involving an opening of the capsule (e.g. lateral release). 19. Slight swellings have been observed and described in the literature in cases where roller pumps are used in arthroscopy. This build-up of fluid can lead to postoperative swellings and pathological changes in patients. It is of the utmost importance that the surgeon monitors both the system and the patient closely while the roller pump is in operation. 20. Always start with the lowest possible pressure to achieve the desired joint distention. Continue to increase distention pressure until a clear liquid medium is obtained. 21. The initial pressure settings are recommendations. It is always appropriate and prudent to use the lowest possible pressure setting to minimize extravasation and any other pressure-related injury to the patient. 22. User-programmed “Pressure Set” values are increased by as much as 50%, but not to exceed a pump pressure of 120 during the LAVAGE function. Exercise caution to avoid injury to the patient. 23. After autoclaving, the accessory devices are VERY HOT. Handle with care to avoid burns. 24. Caution: Federal law restricts this device to sale by or on the order of a physician. 25. This device is intended to be used by a trained medical professional. 26. Detailed instructions on the use and limitations of this device should be given to the patient. 27.

2.0 Product Description 2.1

Product Description and Intended Use The Arthrex AR-6485 CW4 Arthroscopy Pump is a system that maintains constant, non-pulsed control of intra-articular rinsing and distention pressure throughout all phases of an arthroscopic surgical procedure. The AR-6485 is intended to provide continuous pulse-free flow that reacts immediately to changes in the intra-articular pressure so that joint distention can be sustained even under high shaver extraction volumes or secondary outflow.

W A R N I N G ! All fluid inflow devices, including gravity assist, may cause fluid extravasations into the surrounding tissues. This extravasation may be mild, moderate, or severe. In severe cases, the resulting edema may result in a serious adverse patient event which may include compartment syndrome, nerve compromise, or death. Undiagnosed capsular defects will exacerbate fluid extravasation conditions. When utilizing any fluid management device, the patient (extremity and surrounding area) must be monitored closely by the surgical team for signs of excess fluid buildup. Fluid usage volumes should be monitored and compared to similar surgical procedures. With all arthroscopy pumps, correct setup and proper user operation is required. Always select the lowest possible pressures in order to achieve the required intra-articular distention. All alarms or alerts must be acknowledged and the appropriate troubleshooting procedure followed.

W A R N I N G ! FAILURE TO FOLLOW THE SETUP INSTRUCTIONS AND/OR CONTINUING TO USE THE PUMP WITHOUT RESOLVING AN ALARM CONDITION COULD RESULT IN A SERIOUS PATIENT ADVERSE EVENT. Failure to adhere to the setup instructions and use of Arthrex certified tubing may result in inaccurate pressure sensing and monitoring by the device. It is imperative that the user is aware that patient safety may be compromised when an alarm on the pump is ignored or silenced incorrectly. NEVER ignore or silence alarms. Follow the appropriate troubleshooting procedures and carefully monitor the patient. Only Arthrex certified tubing must be used.

W A R N I N G ! This device is only for use in normal arthroscopic procedures as described in the User’s Guide, under the supervision of a trained and licensed physician. This device should not be used by untrained personnel or used for indications other than those described in this User’s Guide.
