Abstract: Implantable fasteners that can be repositioned after implantation, and implants including these repositionable implantable fasteners, have been developed. The fasteners are designed to fixate medical devices and other implantable components in the body, and can be adjusted after initial fixation in tissue to reposition the implanted medical device. The fasteners include a plurality of tissue retainers emanating from a supportive backing, wherein the tissue retainers can swivel from the plane of the supportive backing to engage tissue. The fasteners are fixated in tissue by movement in a first direction, and can be removed when pulled in a direction opposite to the first direction. The fasteners may be attached to medical devices before or after implantation. In one embodiment, the implant is a mastopexy device in the form of a mesh and the repositionable fastener.
