Publication number: 20140257346Abstract: A device having one or more adjustable loops or coils associated with an implant body for use in soft tissue reconstructions is provided. One exemplary embodiment of a device includes a body and a suture filament, with the filament being used to form a self-locking sliding knot disposed on a top side of the body and a plurality of adjustable coils that are substantially disposed on the body's bottom side. Terminal ends of the filament located above the body's top side can be passed through an opening of a Lark's Head knot from opposite sides, thus forming a self-locking sliding knot, and then the terminal ends can be tensioned to adjust a circumference of the coils. Changing a coil's circumference changes a location of a ligament graft disposed on the coil. Other configurations of devices and systems, as well as methods for performing ACL repairs, are also provided.Type: ApplicationFiled: March 11, 2013Publication date: September 11, 2014Applicant: DePuy Mitek, LLCInventors: Mehmet Z.

Patent number: 8821543Abstract: An adjustable anchor system for securing tissue to bone, including an anchor having at least one passage extending from a proximal end toward a distal end. The passage defines a restriction such as a restricted opening. The anchor has at least one bone-engaging feature disposed between the proximal and distal ends. The system further includes a first material formed as a closed loop and capable of being placed through a portion of the tissue, and a second filament having a terminal end, a post limb and a sliding knot tied between the terminal end and the post limb to establish an elongated, adjustable-length loop which extends beyond the proximal end of the anchor and captures the closed loop of the first material. The knot of the second filament is restrained by the restricted opening when tension is applied as desired to the post limb to shorten the elongated loop to draw the tissue toward the anchor.Type: GrantFiled: December 23, 2010Date of Patent: September 2, 2014Assignee: DePuy Mitek, LLCInventors: Joseph Hernandez, Mehmet Ziya Sengun, Gerome Miller
