Patent number: 11395681Abstract: A woven retention device that is configured to receive a fastener in a bone hole can be configured to promote bone ingrowth and impede biofilm formation. The woven retention device can be made of woven filaments that outline apertures of varying sizes and shapes and can serve as an interface between the fastener and the bone material. In a first relaxed state, the interwoven filaments can outline apertures of varying sizes and shapes within a predetermined range and in a second constricted state inside the bone hole with the fastener the interwoven filaments can outline apertures of decreased area that still fall within the predetermined range. The woven retention device can be configured to allow for optimal bone growth while at the same time minimizing the likelihood that biofilm forms thereon.Type: GrantFiled: December 8, 2017Date of Patent: July 26, 2022Assignee: WOVEN ORTHOPEDIC TECHNOLOGIES, LLCInventors: Robert Luzzi, Francis Patrick Magee
