Open helical organic tissue anchor having recessible head and method of making the organic tissue anchor
InactiveUS7189251B2Easy to anchorStrengthens helixSuture equipmentsPinsSelf reinforcedLigament structure
The invention relates to a tissue anchor which is an open helix of biocompatible material having a slope of from 0.5 to 10 turns per centimeter, a length from 3 to 75 millimeters, a diameter of from 1.5 to 11 millimeters, and an aspect ratio of from about 3 to about 5 to 1. The anchor can have a head which is capable of securing or clamping tissue together, such as holding a suture to secure a ligament or tendon to bone. The anchor can also have a head which causes an inward, compressive loading for use in fastening bone to bone, orthopedic plates to bone, or cartilage to bone. The head may be an integral member and may include a self-reinforcing wedge which joins the helix to the head. Further, the elongate member, or filament that forms the helix may have a tapering diameter along its length.

A thermal interface material is described for thermal coupling of an electronic component to a thermally conductive member. The thermal interface material includes a viscoelastic polymer matrix material, fusible solder particles in the matrix material, and filler particles in the matrix material. The solder particles have a melting temperature below a selected temperature (e.g. 157° C. for indium) and the filler particles have a melting temperature substantially above the selected temperature (e.g. 961° C. for silver). The filler particles keep the thermal interface material intact under adverse thermal and stress conditions.

Braze and electrode wire assemblies, e.g., used with an implantable microstimulator, include a wire welded in the through-hole of an electrode, which electrode is brazed to a ceramic case that is brazed to a metal ring that is welded to a metal can. The braze joints are step or similar joints that self-center the case, provide lateral support during braze assembly, and provide increased surface area that prevents braze material from exuding from the joints. The end of the ceramic case that is brazed to the metal ring need not be specially machined. The shell has a reference electrode on one end and an active electrode on the other, and is externally coated on selected areas with conductive and non-conductive materials.
