Abstract
A suspension liner for a residual limb has a liner body with a plurality of anterior and posterior projections formed from a thickness of the liner body. Medial and lateral tendons are located between and correspond to profiles of the plurality of the anterior and posterior projections such that the medial and lateral tendons are located on opposed sides of the liner body relative to one another. The medial and lateral tendons flare circumferentially toward proximal and distal sections of the liner body.

A suspension liner for a residual limb, comprising:
- a liner body having proximal and distal sections with a central section located therebetween, the liner body having an open end at a proximal end of the proximal section and a closed end at a distal end of the distal section;
- a plurality of anterior projections formed from a thickness of the liner body;
- a plurality of posterior projections formed from a thickness of the liner body;
- wherein a medial tendon is located on a medial side of the liner body, and a lateral tendon is located on a lateral side of the liner body, the medial and lateral tendons separating the plurality of anterior and posterior projections;
- wherein the projections fall within a contour defined by adjacent and bordering proximal and distal sections of the liner such that the projections do not extend beyond the contour of the liner body.
A suspension liner for a residual limb, comprising:
- a liner body having proximal and distal sections with a central section located therebetween, the liner body having an open end at a proximal end of the proximal section and a closed end at a distal end of the distal section;
- a plurality of anterior projections formed from a thickness of the liner body and having variable lengths about the circumference of the liner body;
- a plurality of posterior projections formed from a thickness of the liner body;
- medial and lateral tendons located between and corresponding to a profile of the plurality of the anterior and posterior projections, the medial and lateral tendons located on opposed sides of the liner body relative to one another, the medial and lateral tendons continuously blend into and with a surface of the liner body outside of the plurality of anterior and posterior projections, the medial and lateral tendons each define a central region having a narrower width than end portions that continuously blend with the liner body;
- wherein the medial and lateral tendons are thicker about a circumference of the liner body corresponding to the plurality of the anterior and posterior projections than portions of the liner body outside of the medial and lateral tendons.
