Patent number: 10555822Abstract: A device for performing a surgical procedure on a knee includes an adjustable femoral portion, a tibial portion and at least one sensor coupled with the femoral and/or tibial portions to sense pressure exerted by the femoral and tibial portions against one another. The femoral portion is adapted for removably coupling with a distal end of a femur to adjust tension in soft tissue adjacent the knee and has at least one positioning feature adapted to move relative to the distal end of the femur as the femoral portion is adjusted, thus helping position a femoral prosthetic on the distal end of the femur. The sensor(s) may be adapted to sense pressure at medial and lateral sides of the knee, and relative pressures may be displayed as data on a visual display. Adjustments to the femoral member may be made to balance pressure at flexion and extension of the knee.Type: GrantFiled: January 13, 2017Date of Patent: February 11, 2020Assignee: Synvasive Technology, Inc.Inventors: Michael G. Fisher, Anthony K Hedley, Michael Howard, Kevin M Cordes, Toshinobu Katsuya

Patent number: 7442196Abstract: Dynamic knee balancing devices, systems and methods provide for enhanced total knee arthroplasty (“TKA”) procedures. Devices generally include a stationary femoral member for removably attaching to a distal femur and an adjustable femoral member coupled with the stationary member for adjusting ligament tension of the knee. The adjustable femoral member includes at least one positioning feature for providing positional and/or orientation information for facilitating the TKA procedure. Additionally, the adjustable femoral member is movably couplable with a tibial member engaged with the proximal tibia to allow movement of the knee through a range of motion without removing the device from the joint space. When the adjustable femoral member is adjusted, the positional feature(s) move relative to the distal femur to provide positional information.Type: GrantFiled: February 6, 2004Date of Patent: October 28, 2008Assignee: Synvasive Technology, Inc.Inventors: Michael G.
