Having my Alpha silicone gel liners blow-out at the distal anterior
edge has disappointed me. It occurs sometimes within a month. I have
been experimenting with modifications and wanted to share a limited
success.
The latest experiment involved reinforcing this section of the sleeve
with a soft, strong, flexible mesh. The mesh had to have strength
greater than the alpha and its nylon covering, but still be flexible
enough to roll on the stump as easily as the original product.
I am an anesthetist (US- type) and spend a lot of time in surgery.
The surgeons use a flexible mesh to reinforce weakened muscle walls
where hernias form. I used leftovers of this polypropylene product.
It has worked great and extended the life of my last Alpha by a
factor of 2---and still counting. However, it is beginning to
stretch.
For the next prototype, I would like to try a material that is just
as flexible but stronger, such as Kevlar. Does anyone have access to
this material or know how one might get a hold of small quantities?

I will gladly share more details will any interested parties. Best of
luck to all of us.
