Patent number: 10682166Abstract: A spinal procedure includes attaching a first reduction instrument to a first guide assembly and a second guide assembly. The first reduction instrument includes a fixed attachment assembly and a translating attachment assembly that cooperatively interfaces the fixed attachment assembly. The first guide assembly is attached to a first pedicle and the second guide assembly is attached to a second pedicle. The first reduction instrument is moved to reduce an orientation of the spine, while imaging a reduction of the orientation of the spine. An angle and position of the first reduction instrument is locked upon achieving a desired reduction. The spine may then be fused.Type: GrantFiled: May 21, 2018Date of Patent: June 16, 2020Assignee: NuVasive, Inc.Inventors: Tyler G. Smith, Michael Krasovic, Brian Wade Adams

Patent number: 10555763Abstract: A dynamic subsidence plate is described having a first plate member and a second plate member in sliding engagement that may infinitely subside between a first and second assembled position. The plate includes a lock assembly associated with the first and second plate members. The lock assembly includes a ramp portion, an interference portion, and a bearing member situated between the ramp portion and the interference portion. The lock assembly of the plate is configured to allow movement of the first member with respect to the second member in a first direction in an infinite number of positions between a first assembled position and a second assembled position. Further, the lock assembly alternatively prevents movement of the first member with respect to the second member in an opposite second direction between the first and second assembled positions.Type: GrantFiled: December 21, 2015Date of Patent: February 11, 2020Assignee: Stryker European Holdings I, LLCInventors: Charles L. Bush, Jr., Carla Bandeira

Patent number: 10492929Abstract: A surgical tool and method for separating a femoral cup or a femoral ball from an implanted femoral implant without disturbing the femoral implant. The tool is comprised of upper and lower lever arms which turn on an adjustable fulcrum. The upper lever arm has a distal end adapted to engage a femoral cup or a femoral ball and the distal end of the lower lever arm engages the implant. Proximal ends of the lever arms engage a drive assembly which is used to cause the distal ends to move away from one another thereby separating the femoral cup or ball from the femoral implant.Type: GrantFiled: May 30, 2017Date of Patent: December 3, 2019Assignee: JOINT INNOVATION TECHNOLOGY, LLCInventors: Zafer Termanini, Brian VanHiel, Kirk Charles, Taylor Davis

Patent number: 10470754Abstract: A method of treating a patient's joint having opposing joint surfaces includes providing an elongate member having a proximal end, a distal end and an expandable member near the distal end. The expandable member is positioned in the joint between the joint surfaces and expanded so as to separate the joint surfaces away from one another into a distracted position. The joint is manipulated while in the distracted position so that the joint is distracted and in flexion. A diagnostic or therapeutic procedure is then performed on the joint while maintaining the joint in the flexed and distracted position.Type: GrantFiled: December 19, 2016Date of Patent: November 12, 2019Assignee: Pivot Medical, Inc.Inventors: David Boudreault, Vivek Shenoy, Hanson S. Gifford, Mark Deem, Michael Hendricksen, Doug Sutton
