Abstract: A woven retention device, lattice device and woven patch device that are configured to receive a fastener in a bone hole can be configured to impede biofilm formation. The devices can be made of woven filaments that outline apertures of varying sizes and shapes and can serve as an interface between a fastener and the bone material. The devices can be configured to allow for optimal bone growth while at the same time minimizing the likelihood that biofilm forms thereon. The devices can be made of materials that facilitate soft tissue fixation, and screw-activated expansion.
