Publication number: 20190298333Abstract: A suture anchor is disclosed which has an elongated body having a distal end, a proximal end and an exterior surface. An axially oriented bore extends into the body from the proximal end and a proximal portion of the bore has a plurality of abutment surfaces for engaging a tool. The bore includes one or more axially oriented suture passages leading to a suture attachment within the bore. A length of suture extends into the at least one suture passage from the body proximal end and extends to the suture attachment. A screw thread spirals about a portion of the exterior surface of the body adjacent the at least one suture passage.

Patent number: 10117698Abstract: In general, devices, systems, and methods for driving an anchor into bone are provided. In one embodiment, a surgical tool is provided that includes a driver tool with a handle and an elongate shaft. A resistance element is disposed within the handle. An inner portion of an anchor is retained on a distal end of the elongate shaft, and a guidewire extends between the resistance element and an outer portion of the anchor that is in bone. As force is applied distally to the handle, the guidewire pushes the anchor into the bone before overcoming force of the resistance element and thereby allowing the inner portion of the anchor to be driven into the outer portion of the anchor.Type: GrantFiled: March 1, 2016Date of Patent: November 6, 2018Assignee: MEDOS INTERNATIONAL SARLInventors: Gregory R.

Publication number: 20180028203Abstract: A system and method for attaching tissue to bone are provided. In one embodiment, a system for attaching tissue to bone includes a suture, suture anchor, inserter tool, drill, and drill guide having an outer guide and an inner guide. A method for attaching tissue to bone includes attaching a suture to tissue, nesting the suture in a notch on the distal end of the outer guide, passing the suture through a lumen formed in the outer guide, and inserting an inner guide in a lumen formed in the outer guide. The drill guide protects the suture from rotational movement of the drill and allows a user to maintain alignment between the drill guide and the drilled hole. As a result, a suture anchor can be more easily positioned within the drilled hole.Type: ApplicationFiled: October 12, 2017Publication date: February 1, 2018Inventors: Gerome O. Miller, Kevin B.
