Patent number: 11324538Abstract: Disclosed herein are bone plates, bone plate systems, and methods of use thereof that can include a bone plate that includes a plate frame and first and second anvils. The plate frame can have a first surface and define a first opening and a second opening. Each of the first and second anvils can include first and second plates, and a body located in between the first and second plates. The first plate can have a first surface arranged to rest against the first surface of the plate frame when the bone plate is implanted. The second plate can be sized to pass into each of the first and second openings. The body can define a through hole sized to receive a fastener. When the bone plate is implanted, the plate frame can be moveable relative to the first and second anvils.Type: GrantFiled: November 2, 2020Date of Patent: May 10, 2022Assignee: Biomet Manufacturing, LLCInventors: Alfredo Castaneda, Cesare Cavallazzi, Driany Alfonso

Patent number: 10729420Abstract: Systems and apparatuses for soft tissue repair including a device for anchoring sutured tissue to a bone are disclosed. According to one example, the device can include an outer body and an inner member. The outer body can comprise a shell with an outer surface configured to engage the bone of a patient and an inner passage extending longitudinally from a proximal end portion toward a distal end portion. The inner member can be configured to be disposed within the outer body and can be moveable along the inner passage relative to the outer body between a first position and a second position. The inner member can be configured with an eyelet to receive and pass a suture through the member and at least one of the outer body and the inner member can have a first groove extending generally longitudinally along at least a portion thereof. The first groove can be configured to receive the suture therein.Type: GrantFiled: April 20, 2016Date of Patent: August 4, 2020Assignee: Biomet Sports Medicine, LLCInventors: Cesare Cavallazzi, Robert F.

Patent number: 9247946Abstract: A drill sleeve is provided for guiding a bone drill in alignment with the screw holes and drill guides. The drill sleeve includes a cylindrical body having a first end, a second end and a longitudinal axis extending therebetween. The cylindrical body includes a longitudinal bore therethrough that is sized for passage of a bone drill. The drill sleeve also includes a frictional retaining element for exerting a bearing force against the surface of the bone drill, such that the frictional retaining element may support at least the weight of the drill sleeve on the bone drill. The bone drill has graduated indicia, and a portion of the drill sleeve may be referenced relative to the indicia so as to be used as a depth gauge for determining the length of a drilled hole in order to select a screw fastener having the appropriate length.Type: GrantFiled: June 26, 2013Date of Patent: February 2, 2016Assignee: Biomet C.V.Inventors: Cesare Cavallazzi, Marcus Bourda, Sravanthi Avuthu
