摘要:
A woven retention device for interfacing with a bone surface is provided that includes a sleeve body that can surround a fastener, a proximal end for receiving the fastener, and a distal end. The sleeve body includes interwoven monofilaments of different diameters forming a substantially tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. In a first state, the sleeve body has a plurality of combinations of filament cross-section geometries at the intersection points, forming a plurality of protuberance thicknesses as measured in a radial direction of the sleeve body. In a second state when a fastener is inserted into the tubular lattice, pressure from the fastener is transmitted to the tubular lattice such that the spatial relationship of the protuberances changes according to a function of bone density and an interfacing surface shape of the fastener.
