Woven retention devices, systems and methods

A method of dynamically micro-loading a fastener into a bone hole using a woven retention device, the method comprising:

• inserting a woven retention device into a bone hole, the woven retention device having a substantially homogeneous and uniformly, radially distributed pattern of a plurality of interwoven filaments that result in a first spatial relationship of the filaments, apertures, and protuberances, the protuberances being formed at intersections of the interwoven filaments;
• applying pressure from an interfacing surface of a fastener to an interior surface of the woven retention device;
• distributing pressure from the interior surface of the woven retention device to an exterior surface of the woven retention device for transmission of pressure to a bone surface of the bone hole;
• changing, from the pressure from the fastener, the first spatial relationship of the filaments, apertures, and protuberances of the woven retention device into a second spatial relationship of the filaments, apertures, and protuberances according to a function of bone density and according to a function of a shape of the interfacing surface of the fastener;
• and
• interdigitating the woven retention device and the bone surface of the bone hole.

A woven retention device for interfacing with a bone surface, the retention device comprising:

• a sleeve body comprising a plurality of interwoven filaments forming a substantially tubular lattice with a plurality of protuberances distributed on an interior surface and an exterior surface of the tubular lattice at a predetermined spatial relationship, the sleeve body being configured to surround at least a portion of a fastener, each of the plurality of protuberances being formed by an intersection point of two or more of the plurality of interwoven filaments;
• a proximal end that is proximal to the sleeve body and that is configured to receive at least a portion of the fastener;
• and
• a distal end that is distal to the sleeve body, the distal end having a distal tip with a first diameter,
• wherein the receiving portion has a second diameter that is greater than the first diameter,
• wherein in a first, relaxed state, the sleeve body has a plurality of combinations of filament cross-section geometries at the intersection points, the plurality of combinations of filament cross-section geometries forming a plurality of protuberance thicknesses, a thickness of each protuberance being measured in a radial direction of the sleeve body,
• wherein in a second state when surrounding at least a portion of the fastener, the sleeve body is configured to distribute pressure from the fastener to multiple points of contact on the exterior surface such that the spatial relationship of the plurality of protuberances changes as a function of bone density of the bone surface and as a function of an interfacing surface shape of the fastener, and
• wherein the interwoven filaments outline interstices that allow for bone ingrowth, and the interstices formed by the interwoven filaments comprise differently shaped and differently sized interstices.
