I forgot to include the original question with the compiled responses...so
here it is again!

ORIGINAL QUESTION

Dear OANDP-L members:

Does anyone have information on the availability of the following type of
silicone insert:

-3mm thick
-no distal attachment mechanism
-at least 43cm long
-sized to fit distal circumference of 26cm at 5cm from the distal end

We have a number of clients using the Zeroshear insert, formerly distributed
by Silicone Systems South. These clients are knee disarticulation amputees
without a bulbous distal end. The liners extend up and over the proximal
trim line of the sockets and suspend with suction. The Zeroshear liners
were the only liners long enough to accomplish this suspension method.
Silicone Systems South is out of business, to our knowledge, and we are not
aware of any other manufacturers with long enough liners. Your help is
appreciated!

Thank you

Craig Smith C.P.(c)

The result of our request for assistance:

Thank you for the replies. I have responded to the replies after each one.
We are in a situation where we have clients with devices that work very well
for them and we no longer have access to the liners similar to the ones they
are currently using. The Alpha liner is the closest available option
though it has a fabric coating on the outside. We have concerns about this
eliminating the airtight seal as the liner is reflected over the proximal
trim line. We may experiment with a layer of silicone added to the outside
surface of the Alpha to get around the problem.

Sincerely,

Craig Smith

Dear Craig:

Have you tried people at TEC INTERFACE SYSTEMS?

Dear Carlos:

TEC does not recommend reflecting the liners over the socket trim line.

Dear David:

Please see reply to Brian.

Dear Craig

Contact Alps South Corp. @ 1-800-574-5426 I bielieve they will custom make
liners. Good luck.

Dear David and Brian:

Alps will no longer custom make liners as per our conversion with company
recently. We have concerns about the exterior covering of the Alpha liner
because we are using the air tight seal between the liner and the socket
(with the liner reflected over the proximal trim line) as part of our
suspension system. We may have to apply a silicone layer to the outside of
the Alpha in order to maintain a seal. They do appear to be the correct
thickness and length.

The Alpha Cushion Liner from Ohio Willow Wood fits this description.
Part number ALC-5036 would meet all of the above criteria.
