Abstract: Disclosed and claimed herein is an improved leg brace having a thigh frame, a shank frame, a knee assembly rotatably coupling the thigh frame to the shank frame, and a shoe component attached to the shank frame; the knee assembly having a spring, clutch, means for engaging the clutch; and programmable means for engaging the clutch at a selected angle between the thigh frame and shank frame.

Abstract: Disclosed and claimed herein are spiral torsion springs, non-linear torsion springs, and non-linear torsion spring assemblies. These devices are useful in damping applications, orthotic joint applications and servo control applications.

Abstract: A device for mixing and delivering a mixture of fluids to a target site includes a tube for containing the mixture. A compressible auger for mixing the fluids is movably disposed within the tube, one end of the auger being free at the distal end of the tube. A plunger is also movable within the tube in communication with the other end of the auger. When the plunger is moved axially within the tube the auger also moves axially and the auger is compressed to dispense the fluid. The mixing and delivery device can be used with an apparatus for the arthroscopic delivery of a tissue repair material to a repair site. The apparatus includes a first sheath and a second sheath removably attached to the first sheath for delivering the tissue repair material to the repair site.

Abstract: Embodiments of the invention relate to walking/running braces and to devices for enhancing locomotion, specifically human bipedal locomotion. More particularly, it relates to a controlled mechanical device which provides support of the torso via the hip sockets, reduces the metabolic energy associated with walking/running and reduces the incidence of falls caused by insufficient leg thrust. Embodiments of the invention also relates to reducing the strain and metabolic energy consumption associated with walking/running with a heavy backpack or other significant carried load.
