The Medi Genu Protector Sleeve is intended to prevent premature failure of B/K (below-the-knee) prosthetic sleeves. Many prosthetic sockets are lightweight and thin with socket trimeline edges that can prematurely wear out a prosthetic sleeve. The Medi USA Sleeve Protector increases the longevity of your prosthetic sleeve by creating a slick barrier between the socket and sleeve. The Medi Genu Protector Sleeve adheres to your socket with silicone beads that line the bottom preventing any movement. When the Medi USA Protector Sleeve is used, the inner surface of your prosthetic sleeve is protected from foreign materials and abrasive edges.
