A tendon repair implant for treatment of a partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by an arthroscopic means approach that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.

A system and method for controlling a device, such as a prosthetic limb are provided. A biomimetic controller of the system comprises a signal processor and a musculoskeletal model. The signal processor processes M biological signals received from a residual limb to transform the M biological signals into N activation signals, where M and N are integers and M is less than N. The musculoskeletal model transforms the N activation signals into intended motion signals. A prosthesis controller transforms the intended motion signals into three or more control signals that are outputted from an output port of the prosthesis controller. A controlled device receives the control signals and performs one or more tasks in accordance with the control signals.

A method and apparatus are disclosed for providing a compression fixation between a first and further component. The apparatus comprises an elongate body having a head end and a tip end and comprising a screw thread including a first region in which the screw thread has a corresponding first pitch and a further region, extending from the tip end, in which the screw thread is tapered and has a corresponding farther pitch that continually decreases away from the tip end.

The invention relates to a muscle membrane intended to be affixed to a muscle of a human or animal body, the membrane being capable of at least partially surrounding the muscle, the muscle comprising fibres covered with an outer tissue, the positioned membrane having a shape that is identical to that of the muscle. The membrane is characterised in that it exhibits anisotropic behaviour so as to reproduce the mechanical behaviour of the muscle, the membrane comprising: -a matrix designed in a biocompatible material having an elasticity similar to that of the outer tissue of the muscle, -one or more reinforcing strips rigidly attached to the matrix, each strip being designed in a biocompatible material having an elasticity similar to that of the fibres it covers and each strip being oriented according to membrane stiffening requirements and according to the expected muscle correction.

A conductive hydrogel fiber including a hydrogel network formed from a water-soluble hydrogel polymer and conductive fillers dispersed therein is provided. The hydrogel network includes a porous structure having nanofibrillar network walls, the surfaces of which are provided with interconnected crystallized nanofibrils formed by concentration and aggregation of the hydrogel polymer. The conductive hydrogel fiber exhibits high electrical conductivity, excellent tensile strength, large elongation at break, high toughness, and low swelling in water.

A quadricep graft suspension construct, having a button loop, including a generally rectangular button, defining four apertures, including an innermost pair of apertures; and a suture loop looping through the innermost pair of apertures. The construct also has a graft holding assembly, including a reinforcement of first fibers braided with two second fibers, and wherein the first fibers have a first and second lengthwise end and the second fibers continue separately, extending from the first lengthwise end to form a pair of first tails and from the second lengthwise end to form a pair of second tails and wherein the first tails are jointly swaged to a needle. And wherein the graft holding assembly is affixed to the suture loop at a position opposed to the button at least in part by the second tails being joined together about the suture loop and further includes a packaging holding the needle.
