Publication number: 20220313241Abstract: Various devices, systems, and methods for anchoring sutures are provided In general, a suture anchor can include a groove formed in an exterior surface thereof and configured to seat a suture at least partially therein. The suture can be configured to automatically become seated in the groove during the advancement of the anchor into bone, such as by being rotated therein using a driver tool. The suture and the groove can have cooperating sizes such that the suture seated in the groove extends radially outward therefrom to be partially located outside of the anchor. This external portion of the suture can be press fit between the anchor and the bone, thereby securing both the anchor and the suture to the bone. This securing can occur as part of driving the anchor into bone.Type: ApplicationFiled: June 17, 2022Publication date: October 6, 2022Inventors: David B. Spenciner, Steven N. Bittenson

Publication number: 20220000623Abstract: Devices and methods for tissue and graft procedures are provided that are designed to fail under a certain amount of force, providing sensory feedback that a particular activity may be providing too much stress on a surgical implant. For example, a surgical implant can include a sacrificial element in the form of a filament designed to break when a certain threshold value of force is met or exceeded, while a second filament that has the ability to withstand higher values of force, is able to maintain the repair after the first filament fails. In other embodiments, the sacrificial element includes a filament engagement mechanism associated with a suture anchor configured to fail at a threshold value of force, and a second filament engagement mechanism of the anchor can maintain the repair after the first one fails. Many implants configurations are provided, as are various surgical methods incorporating sacrificial elements.Type: ApplicationFiled: September 15, 2021Publication date: January 6, 2022Inventor: David B.

Publication number: 20210169466Abstract: 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: December 23, 2020Publication date: June 10, 2021Inventors: Mehmet Ziya Sengun, Hugh S.
