Patent number: 11304693Abstract: The present disclosure provides staples, and corresponding staple guides, for applying a compressive force between biological elements. The staples may include a bridge portion and a pair of tines extending from the bridge portion configured for implantation into biological elements. The tines may be spaced a first distance in a first state of the bridge portion. The bridge portion may be elastically deformable into a second state with the pair of tines spaced a second distance that is greater than the first distance and the tines pre-loaded to apply a compressive force therebetween. The guides may include a staple engagement portion operable to maintain the biased state of the staple, and/or a drill guide portion operable to facilitate the formation of apertures spaced the second distance in the biological elements.Type: GrantFiled: August 13, 2019Date of Patent: April 19, 2022Assignee: Zimmer, Inc.Inventors: Lon S. Weiner, Jorge Montoya, John R. Pepper, Stuart D. Katchis, Lawrence Kiefer

Patent number: 9615870Abstract: A method for applying compression to a joint includes providing an intramedullary fixation assembly having a proximal screw member positioned at a proximal end of the intramedullary fixation assembly and a lag screw member positioned at a distal end of the intramedullary fixation assembly. Medullary canals are drilled in a first and second bone and the medullary canals are reamed. The proximal screw member is inserted into the first bone and a drill is used create a dorsal hole in the first bone. The lag screw member is slideably coupled to the dorsal hole and to the proximal screw member and into the second medullary canal. A torque is applied to the lag screw member to apply compression to the joint.Type: GrantFiled: April 21, 2015Date of Patent: April 11, 2017Assignee: EXTREMITY MEDICAL, LLCInventors: Jeff Tyber, Jamy Gannoe, Lawrence Kiefer, Brian Gerard Donley, Brian Adams
