Abstract: A surgical fastener for anchoring medical devices to tissue includes first and second legs lying in a first plane, and third and fourth legs lying in a second plane that is orthogonal with the first plane. A bridge interconnects proximal ends of the four legs for forming a closed end of the surgical fastener. Each leg has a proximal end, a distal end, and an insertion tip with a distal point located at the distal end of the leg. Each leg has an insertion tool alignment guide that extends between the proximal and distal ends of the leg and along a longitudinal axis that is aligned with the distal point of the insertion tip.

Abstract: A wound closure device including a first tissue anchor with a first suture filament fixedly coupled thereto at a proximal end and extending along a length to a free distal end, and a second tissue anchor with a second suture filament fixedly coupled thereto at a proximal end and extending along a length to a free distal end. The first suture filament is configured to form a slip knot at its proximal end substantially adjacent the first tissue anchor, and the second suture is configured to form a slip knot at its proximal end substantially adjacent the second tissue anchor. The length of the first suture filament passes through the slip knot of the second suture and the length of the second suture filament passes through the slip knot of the first suture filament.

Abstract: A method for controlling digit movement of a prosthesis based on residual forelimb volitional pressures is provided. A filter is provided for discriminating from the distributed pressures to provide reliable digit control. The extracted commands can be used to control actuators in a hand prosthesis to restore biomimetic finger control to the user. Feature extraction algorithms can be based on signal amplitudes (peak amplitude or root mean square). Training signal validation can be based on cepstral encoding. The filter is trained under user supervision.
