Abstract

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.

Dependent claims

A method of inserting a tubular woven retention device, comprising:

inserting the tubular woven retention device into a bone hole, wherein the tubular woven retention device has a plurality of protuberances formed by an intersection of filaments;
and
distributing pressure from a fastener being inserted into the tubular woven retention device from an interior surface of the tubular woven retention device to an exterior surface of the tubular woven retention device for transmission of pressure to a bone surface of the bone hole according to a function of bone density and according to a function of an interfacing surface shape of the fastener,
wherein the pressure from the fastener changes a spatial relationship of protuberances of the plurality of protuberances on the interior surface of the tubular woven retention device, and
wherein the pressure from the interior surface changes the spatial relationship of protuberances of the plurality of protuberances of the exterior surface of the tubular woven retention device which allows interdigitation of the tubular woven retention device with the bone surface.
