Pressure Transmitters
Following removal from the animal, the transmitter should be rinsed to remove gross contamination from blood and
tissue. Carefully remove any residual tissue adhesive from the surface of the catheter. Remove any suture material
present. If there is blood in the tip of the catheter, remove as much as possible by directing a stream of saline at the
tip to flush it out. The transmitter can then be placed into the enzymatic detergent and allowed to soak in the
detergent for at least 30 minutes to allow breakdown of the surface contaminants. The transmitter should be
removed and examined. If traces of blood or tissue remain, use gauze to wipe the surface until it is clean. The
catheter should be wiped very carefully using wet gauze. Do not try to wipe the thin-walled section. Rinse the
transmitter in tap water thoroughly.
Place the transmitter into fresh 2% activated glutaraldehyde (shelf life of 14 days). The transmitter should be left in
the glutaraldehyde for at least 4 hours. For the best results, we recommend overnight (12 hours). Place the
transmitter into sterile saline for 15-30 minutes to rinse away the glutaraldehyde. We recommend at least two
separate rinses. Following the final rinse, the transmitter can be left in the saline until ready for implantation. The tip
of the catheter should be filled with replacement gel at the time of surgery. This should be done aseptically to
prevent contamination
Multiplus Transmitters
For transmitters with multiple sensors, follow the instructions for the most delicate sensor on the transmitter
(typically pressure).
Refurbishment of Transmitters
The following instructions are provided to answer any questions you have about returning any items to DSI. If you
follow these procedures, we will know the exact reason the products are being returned as soon as they arrive and
can begin processing them immediately. Please contact your DSI representative if you have any additional
questions.
1) Explanted transmitters may constitute a biohazard! To prevent delays, follow cleaning & disinfection
instructions carefully.
a. Clean explanted transmitter using an enzymatic detergent to remove ALL blood, tissue debris, suture
material, etc.
b. Soak clean transmitters in a 2% solution of hospital disinfectant such as glutaraldehyde for at least 20
minutes. Rinse and allow to air dry.
c. Place disinfected transmitters into the zip-lock bag provided by DSI before shipping as indicated in
number five (5) below.
d. Shipments that have obviously not been cleaned and disinfected will be rejected and sent back to the user
at their expense plus a $25 handling fee.
2) Obtain a purchase order prior to returning the goods. Many companies and institutions will issue blanket
purchase orders that will cover several shipments. One of the most common reasons for delays in returning
devices is the lack of a purchase order. Having a blanket purchase order will save you time and the difficulty
of having to obtain a new purchase order each time you return implants for refurbishment and allow us to serve
you better.
3) Fill in the Returned Materials Form you received with your implants and fax the form to DSI at
(1-651) 481-7404 prior to returning any products to us for refurbishment, repair, or return of items on loan. A
copy of the RMA form MUST accompany your shipment.
4) Please indicate on the RMA form the serial number of any device that exhibited performance problems and
the type of problems you noticed. Please also identify any products that had been loaned to you.
