Patent number: 11576689Abstract: A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.Type: GrantFiled: December 15, 2020Date of Patent: February 14, 2023Assignee: Biomet Manufacturing, LLCInventors: Robert Metzger, Keith R.

Patent number: 11253400Abstract: The present disclosure relates generally to the field of medical treatment and therapy of mammalian tissue. More specifically, it relates to coverings and/or dressings that provide negative pressure at mammalian tissue sites, such as at one or more sites of surgical, non-surgical, and/or traumatic wounds, to promote closure and healing of the wounds. A key embodiment of the disclosed invention entails the use of a dressing that comprises a sponge that is shaped so as to create a vector force inward bringing wound edges together to promote healing, especially upon application of negative pressure. Other key features of the disclosed invention are its simplicity, its low cost, and that it is completely mechanical and lacks the need for any electronic components. The disclosure also relates to devices, systems, kits and methods for providing said negative pressure at said mammalian tissue sites and promote healing.Type: GrantFiled: April 17, 2019Date of Patent: February 22, 2022Assignee: MIDWEST TRAINING AND DEVELOPMENT SERVICES, LLCInventors: Christopher G. Zochowski, Keith R. Berend

Patent number: 10973580Abstract: A method of preparing a surgical plan comprises video capturing a range of motion of an anatomic joint of a patient to obtain a range of motion video, registering the range of motion video to two-dimensional images of a skeleton of the patient, identifying potential impingement and stability issues in the anatomic joint based on the range of motion video, templating a prosthetic implant on two-dimensional images of the anatomic joint using the identified potential impingement and stability issues of the anatomic joint to obtain position and orientation data, and electronically saving the position and orientation data of the prosthetic implant for use with a surgical navigation system. A system for planning and performing a surgical procedure comprises a motion capture system, an x-ray system, an electronic modeling system, and a surgical navigation system.Type: GrantFiled: March 25, 2016Date of Patent: April 13, 2021Assignee: Biomet Manufacturing, LLCInventors: Michael E.

Patent number: 10687947Abstract: A method of securing an orthopedic hip prosthesis to an acetabulum of a living being. The prosthesis can be a shell or a cup, and the surgery can be a total hip arthroplasty such as a revision total hip arthroplasty. In some examples the method can include placing an augment at a bone surface of the acetabulum, applying a layer of fixation material over the bone surface in an amount sufficient to cover the augment, and then implanting the prosthesis over the layer of fixation material to secure the prosthesis to the layer of fixation material. In various aspects of the method, the augment can be an anchor or a spacer.Type: GrantFiled: May 11, 2018Date of Patent: June 23, 2020Assignee: Biomet Manufacturing, LLCInventors: Keith R.

Patent number: 10188520Abstract: An implant for a hip can include a lateral augment adapted to be coupled to a lateral side of a femoral body implant. The lateral augment can include a body portion having a first surface, a second surface opposite the first surface, and a protrusion extending from the second surface. The protrusion can have a shape adapted to mate with a complementary shaped recess formed in the lateral side of the femoral body implant. An aperture can be positioned in the body portion and extend through the protrusion. A fastener can be received through the aperture and adapted to be threadably secured to the lateral bore. The fastener can be configured to have a length sufficient to pass through a portion of a greater trochanter for securing the portion of the greater trochanter and the lateral augment to the femoral body implant.Type: GrantFiled: October 31, 2016Date of Patent: January 29, 2019Assignee: Biomet Manufacturing, LLCInventors: Aaron P.

Patent number: 10172723Abstract: Systems, devices, and methods are provided for measuring forces in the space of a knee during surgery. Such forces can be caused by tension in the ligaments of the knee. A femoral member is engaged with a distal femur. While the knee is flexed, partially extended, or fully extended, a force sensor and a gauge shim can be placed in the gap between the femoral member and the tibial plateau to measure the forces therebetween. The force sensor provides an accurate and quantifiable measurement of force, making knee replacement surgery and ligament tension balancing more accurate, standardized and repeatable. The force sensor comprises an elongate housing which comprises a thin force sensing distal portion and a proximal handle portion.Type: GrantFiled: July 12, 2017Date of Patent: January 8, 2019Assignee: Synvasive Technology, Inc.Inventors: Michael G.
