Patent number: 10966704Abstract: Disclosed are systems and methods for performing soft tissue repair by delivering a suture through the soft tissue and underlying bone at two or more fixation points that can be spaced apart from each other and connected by the suture on the surface of the soft tissue. The two or more fixation points and the suture connected there between can be a continuous strand of suture, which can form a stitching assembly that can provide sufficient fixation in the bone and minimize disruption to the soft tissue and bone. In an example, the suture can be delivered into the bone using one or more implants that can catch the suture to drive the suture through the tissue and into the bone. The one or more implants can include structural features to aid in securing the suture to the implant. In an example, the suture can include structural features or be formed of a material to aid in fixation of the suture in the bone.Type: GrantFiled: November 9, 2017Date of Patent: April 6, 2021Assignee: Biomet Sports Medicine, LLCInventors: Antony J. Lozier, Matthew Prygoski, Daniel P. Murphy, Hallie E. Brinkerhuff, Michael Giordano, J. Craig Fryman, Alex McMullen, Kevin T. Stone

Patent number: 10179017Abstract: A orthopedic tool (10) for bone fixation is provided for driving a bone pin into a fractured bone to stabilize the fractured bone by maintaining the fractured bone in a reduced state. The tool may be a handheld device including a magazine (56) having a plurality of passageways (98) containing one or more bone pins (62) positioned within the passageways. The tool may also include a pneumatically—powered piston (64) having a projection (70) that is sized for receipt within the plurality of passageways, the projection applying sufficient force to the bone pin to drive the bone pin out of the magazine and into the fractured bone.Type: GrantFiled: April 3, 2015Date of Patent: January 15, 2019Assignee: Zimmer, Inc.Inventors: Antony J. Lozier, Daniel P. Murphy, Matthew Prygoski, Michael Giordano, Donald L. Yakimicki, Jeffrey Bassett, Michael Scott Collins

Patent number: 9987067Abstract: Various embodiments of the present disclosure include a tool for stabilizing a fractured bone. The tool comprises a barrel having a proximal end and a distal end. The distal end of the barrel includes a passageway for receiving a bone pin configured to be driven into the fractured bone to stabilize the fractured bone. The passageway is sized to accommodate axial movement of the bone pin through the passageway while limiting radial movement of the bone pin in the passageway. The tool further comprises a piston having a proximal end and a distal end and configured to translate axially relative to the barrel. The proximal end of the piston includes a head and the distal end of the piston includes a needle formation, the needle formation being sized for receipt within the passageway of the barrel to drive the bone pin axially from the barrel and into the fractured bone.Type: GrantFiled: July 11, 2013Date of Patent: June 5, 2018Assignee: Zimmer, Inc.Inventors: Michael Giordano, Antony J.

Publication number: 20120059383Abstract: The present disclosure provides a surgical instrument that creates a vacuum seal between a prosthetic component and a surgical instrument to grasp the prosthetic component so that the surgical instrument may be utilized to manipulate the prosthetic component relative to an anatomical structure. The surgical instrument is further designed to be used as an impactor capable of receiving and transferring an impaction force for seating the prosthetic component relative to the anatomical structure without the surgical instrument losing its grasp on the prosthetic component. The surgical instrument of the present disclosure includes a suction device which may be selectively released once the prosthetic component is appropriately positioned and seated relative to the anatomical structure. Such selective release prevents disruption of the positioning of the prosthetic component and facilitates proper placement and implantation of the prosthetic component.Type: ApplicationFiled: July 19, 2011Publication date: March 8, 2012Applicant: ZIMMER, INC.Inventors: Daniel P.
