摘要:
A woven retention device for interfacing with a bone surface includes a sleeve body that can surround a fastener, a proximal end receiving the fastener, and a distal end. The sleeve body includes interwoven monofilaments forming a tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. In a first state of the sleeve body, the protuberances are arranged in a predetermined spatial relationship and each protuberance has a thickness 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 according to a function of an interfacing surface shape of the fastener.
