Abstract

A prosthetic liner having a distal region may stretch anywhere from 0-30% vertically and 10-200% horizontally as compared to the proximal region's vertical stretch of 55- 125% and 100-175% horizontally. The stretch of the liner at various pressure sensitive regions of a residual limb can also be lowered or heightened depending on the area for comfort. A variety of stitches may be used at the distal end to implement this lowered longitudinal stretch. The liner also has an interior layer of elastomer gel. The design of this prosthetic liner is primarily to prevent the "pistoning" of the amputee's residual limb within the liner. The liner also includes the use of a low extensibility material which is adhered to the fabric portion and limits the longitudinal movement while allowing for transversal movement. The customizable nature of the invention allows for shaping and personalization depending on the needs of the user.
