Abstract
Devices and methods for securing a graft with respect to bone are provided. One exemplary embodiment of a surgical implant includes a flexible filament body and a suture filament or repair construct that extends through the filament body at multiple locations. The repair construct is formed into one or more coils, which can receive a graft. The flexible filament body can be configured to be actuated between unstressed and anchoring configurations, the latter of which sets a location of the suture filament, and associated graft, in a bone tunnel. More particularly, the flexible filament body can ball up, or become denser, to a size that cannot pass into the bone tunnel in which the suture filament holding the graft is disposed. The present disclosure also provides for feedback units to assist a surgeon in knowing a location of the implant. Further, other exemplary devices and methods are provided.
