INSTRUCTIONS FOR USE Plastic Interstitial Needles GM11007560-7580, GM11010750
Cautions and Warnings MRI Safety Information
CAUTION: Each physician is responsible for using the appropriate technique and deciding on the indication for use of the Plastic Interstitial Needles based on his own experience, training and medical judgment. The physician must be trained in the proper use of the Varian afterloader. CAUTION: There is no limitation to patient population. Limitations are on the maximal radiation dose applicable to the individual organs. CAUTION: Federal law (USA) restricts this device to sale by or on the order of a physician.
Non-clinical testing and MRI simulations were performed to evaluate the Plastic Interstitial Needles. Non-clinical testing demonstrated that the Plastic Interstitial Needles are MR conditional. A patient with this device can be scanned safely in an MR system immediately after placement under the following conditions:
• Static magnetic field of 1.5 Tesla and 3 Tesla only. • Maximum spatial gradient magnetic field of 10,000 Gauss/cm (100T/m) or less.
• Maximum MR system reported, whole body averaged specific absorption rate (SAR) of 2.0 W/kg for 15 minutes of scanning (i.e., per pulse sequence) in the Normal Operation Mode of the MR system. All stainless steel parts (such as obturators/mandrins, marker wires, length gauges, etc.) must be removed prior to entering the MR environment.
•
MRI Related Heating
CAUTION: If a ClickFit™ connector becomes contaminated during a treatment, clean the connector surfaces by wiping with hospital wipes soaked in detergent solution until contamination is removed, followed by wiping with a hospital wipe soaked in purified water. Allow the connector to dry and place a cleaning cap on it before manual or machine cleaning. CAUTION: Cleaning caps, leak stop buttons and leak stop channel markers are single use devices that must be disposed of after use. A reused cleaning cap, leak stop button or leak stop channel marker might not securely protect the connector of the source or transfer guide tube, so liquid could enter and this could lead to malfunction of or damage to the Varian afterloader. WARNING: Failure to use leak stop buttons or leak stop channel markers may lead to contamination of the needles or source/ transfer guide tubes, which could lead to patient infection. Cleaning caps must be used when instruments are immersed for manual and machine cleaning or disinfection. Cleaning caps must be removed before sterilization so that the inside of the needles can be sterilized.
WARNING: The Plastic Interstitial Needles (GM11007560-7580, GM11010750) were designed solely for use with Varian afterloaders. The manufacturer does not accept responsibility if an afterloader device from another manufacturer is used.
Under the scan conditions defined above, the Plastic Interstitial Needles are expected to produce a maximum temperature rise of less than 1.4º C after 15 minutes of continuous scanning.
Artifact Information In non-clinical testing, the image artifact caused by the Plastic Interstitial Needles extends approximately 5 mm from this device when imaged using a gradient echo pulse sequence and a 3 Tesla MR system.
Indications for Use The interstitial plastic needles with 2 mm diameter, are indicated for use for interstitial brachytherapy treatment in areas such as the head and neck, gynecological, breast and prostate.
General Information Carefully follow these instructions for use. The Plastic Interstitial Needles should only be used by a physician who has received full training in the appropriate Varian afterloader system. The Plastic Interstitial Needles are designed for use within a CT and MRI environment. Each needle is supplied with a stainless steel mandrin, which can also be ordered individually. The needles and their associated mandrins are available in lengths of 113 mm, 200 mm, and 320 mm. The mandrins are inserted into needles to stiffen the needles during implantation of the needles into the patient and to stiffen the needles between radiation therapy fractions. The needles can also be used with interstitial ovoids and ring caps. Note: The hub of the needle that connects to a source
or transfer guide tube is 2.5 mm in diameter.

INSTRUCTIONS FOR USE Plastic Interstitial Needles GM11007560-7580, GM11010750
Delivery Condition and Testing
Assembly and Use
Each Plastic Interstitial Needles is carefully packaged. It is in a clean but non-sterile condition. The packaging should be unopened and undamaged upon receipt. Remove the components from the packaging in a clean environment.
CAUTION: Liquid or other kinds of contamination entering the needles can lead to malfunction of or damage to the Varian afterloader. WARNING: Using a damaged needle can lead to incorrect treatment of the patient and may cause radiation hazards to patients and medical staff.
These needles must be handled carefully to avoid damage. Prior to each treatment, the user must ensure that the needles are undamaged and still meet specifications. Check the needles thoroughly for kinks or damage and for sufficient sharpness of the tip and firm seating of the connector. The needle tip must be undamaged and must not be frayed. Check the mandrins thoroughly for straightness and damage. Needles with a kink should be considered damaged and must not be used, as they can cause serious problems during source movement. Please dispose of them according to local rules and replace them. Bending of a needle is considered normal wear and tear. Slight bending of a needle is generally acceptable, as long as the severity of the bending is not too much as to significantly alter the insertion trajectory. If the bending is severe enough to alter the insertion trajectory, the needle should be disposed of according to local rules and replaced. Before treatment, use the length gauge (GM11000330) for the GammaMedplus to check the correct source guide tube/needle combination length. For the VariSource afterloader, this test should be performed using the measurement ruler, marker wire and marker clip (AL13119000, AL13154000, AL13169000) to check the correct transfer guide tube/ needle combination length.
WARNING: A broken or kinked needle is irreparable and must not be used. It can lead to contamination and incorrect treatment of the patient through underexposure or overexposure and may cause radiation hazards to medical staff.
WARNING: Do not re-sharpen the needles, because this might result in losing the needle tip.
Prior to each use (including the first use), clean, disinfect and sterilize the needles and accessories carefully according to the supplied instructions. During the procedure, use cleaning caps when components are immersed in cleaning, disinfection, and rinse solutions.
Note: In combination with the Titanium Fletcher-style
Applicator Set (GM11006200) or the Vienna Style Build-up Cap (AL07530000 or AL07531000), the 200 mm mandrin may be used to stabilize the connector end of the needle during insertion.
Note: When used with the VariSource afterloader and
connected with a ClickFit™ Transfer Guide Tube (GM19002xxx), the measured length should be 101.4 cm plus the needle length, and the BrachyVision planning length should be 100.0 cm. For example, when connected to a 200 mm needle, the measured length should be 121.4 cm and the BrachyVision planning length should be 120.0 cm. WARNING: An incorrect source or transfer guide tube/needle combination length can lead to incorrect treatment of the patient through underexposure or overexposure. Verify the correct source or transfer guide tube/needle combination length.

Open the packaging and take out the necessary amount of needles and mandrins. Place all components in a sterile environment.
Slide a leak stop button (or leak stop channel marker) over the needle to prevent any liquid from entering the needle connector. CAUTION: Blood or liquid entering the source or transfer guide tube connector can cause the connector to malfunction. Use the leak stop button (GM11003810), leak stop channel marker (GM11010510 or GM11010520) or sufficient pads to protect the connector.
If necessary, place a stainless steel button on the needles.
Insert a suitable mandrin to stiffen the needle. Ensure that the needle does not become bent during implantation.
Following implantation, remove the mandrin and place a sterile cleaning cap over the needle to prevent any liquid from entering the needle.

Repeat the steps above until all needles are in place.
To take radiographs, remove the cleaning cap or mandrin and insert the corresponding X-ray marker. Ensure that the X-ray marker reaches the distal position of the needle. For more details refer to the X-ray marker instructions for use (GM11009600-09680).
WARNING: The patient must be advised about avoiding any movements that might change the position of the applicator or source/transfer guide tubes. If necessary, the patient must contact the treatment staff immediately by intercom or viewing equipment. A shift in position of the applicator or guide tube could lead to misadministration of the treatment.
Note: The dead space of the blunt needle tip is
3.9 + 0.4 mm / -0.2 mm. The dead space of the sharp/standard needle tip is 4.6 ± 0.4 mm.
The patient can now be treated according to the user manual for the Varian afterloader.
Removal and Disassembly
