The implant pressure catheter may become curved or bent after being implanted. This may require a need to straighten the catheter for future use.
To straighten the catheter:
- Soak the transmitter in an enzyme detergent immediately upon explantation to thoroughly clean and remove any biomaterial. Please refer to the On-Site Sterilization Tech Notes for DSI approved and recommended detergents.
- Rinse the catheter and re-gel if necessary.
- Carefully thread the catheter into the beveled end of a syringe needle.
- Mouse - 20 gauge syringe needle
- Small Animal - 14 gauge syringe needle
- Advance the catheter completely into the needle and place the apparatus on a tray.
- Place the tray in a warm (40°C) environment for at least one hour, such as on a water circulating heating pad. The transmitters can also be left in the warm environment overnight.
- Cover the whole heating pad with a towel or other covering. Do not exceed a temperature of 50°C while heating.
- Remove the tray with the implants from the warm environment. The catheters will cool down quickly to room temperature which will set the catheter in its new configuration.
- Once the catheters have cooled, they can be removed from the needle.
