    摘要： A rotary drive member drives a driven member. A ring surrounding the driven member has two cam recesses containing lock members between cam surfaces of cam recesses and the ring. Each recess accommodates an associated lock member at different locations where the recess is shallower. Driving the driven member is permitted in a given rotation relative to the ring, but each lock member inhibits rotation of the driven member in the opposite sense. The recesses extend in opposite directions. Coupling between the driven members is free-play whereby reversal in the rotation disengages members and reengages. Protuberances extending into cam recesses retain a lock member associated with one recess at the deeper location permitting movement of the other lock member towards the shallower location. Upon reversal of the rotation, the protuberances retain another lock member at the deeper location permitting movement of one lock member.

    摘要： A silicone prosthetic liner for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an open proximal end, a closed distal end, and sidewalls comprising an inner layer of molded silicone. The silicone is molded over a mandrel that has been sandblasted using #36 grit at 100 psi so as to form microcraters and reduce the coefficient of static friction.

    摘要： A biased cell configured to flex out-of-plane upon application of a lateral or circumferential force applied to the biased cell, the biased cell having an elongate member projecting axially from an apex of the biased cell that flexes out-of-plane concomitantly with out-of-plane flexion of the biased cell. An integral and monolithic hypotube is fashioned into a lattice structure having a plurality of biased cells and elongate members and is capable of being configured into a cardiac valve. Transluminally implantable cardiac valves configured for use in cardiac valve replacement and/or cardiac valve exclusion that are capable of percutaneous delivery on low-profile catheters having 15 French size or less. The implantable cardiac valves are fabricated of from a unitary metal material to form a lattice frame support having a main body portion and valve leaflet portion, and a plurality of elongate biasing arm members. A polymer coating or covering is disposed on the valve leaflet portion and the elongate biasing arm members and subtends space between adjacent pairs of elongate biasing arm members to form valve leaflet cusps that are biased toward a central axis of the cardiac valve by the elongate biasing arm members.
