Abstract:
A woven retention device for interfacing with a bone surface includes interwoven filaments forming a tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. The protuberances are formed by intersecting interwoven filaments. The retention device receives and surrounds a fastener. In a first, relaxed state, the retention device has multiple combinations of filament cross-section geometries at the intersection points, and the multiple combinations of filament cross-section geometries form multiple protuberance thicknesses. In a second state when surrounding at least a portion of the fastener, the retention device distributes pressure from the fastener to multiple points of contact on the exterior surface of the retention device such that a spatial relationship of the protuberances changes as a function of bone density of the bone surface and as a function of an interfacing surface shape of the fastener.
