Patent number: 10959832Abstract: A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of hone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression.Type: GrantFiled: October 5, 2018Date of Patent: March 30, 2021Assignee: Cayenne Medical, Inc.Inventors: Kevin N. Baird, Derek J. Harper, Joe P. Kovalski, Kenneth D Montgomery

Patent number: 8870955Abstract: An anterior cruciate ligament (ACL) surgical repair technique involves the use of a single femoral and tibial tunnel and an implant that separates and positions two distinct bundles. This allows for the surgeon to create a more anatomic reconstruction with a procedure that is less technically demanding, can be performed using a transtibial or anteromedial approach, minimizes tunnel widening, and decreases operative time. The result is a strong fixation option for soft tissue grafts, with circumferential graft compression at the aperture, high pull-out strength, and ease of use. The graft bundles are positioned in a more anatomic orientation through the above noted single femoral and tibial tunnel.Type: GrantFiled: June 22, 2012Date of Patent: October 28, 2014Assignee: Cayenne Medical, Inc.Inventor: Kenneth D.

Patent number: 8465545Abstract: A material fixation system is particularly adapted to improve the tendon-to-bone fixation of hamstring autografts, as well as other soft tissue ACL reconstruction techniques. The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.Type: GrantFiled: May 19, 2011Date of Patent: June 18, 2013Assignee: Cayenne Medical, Inc.Inventors: Kenneth D. Montgomery, Derek J. Harper, Kevin N. Baird, Joe P. Kovalski, David G. Spilka

Patent number: 8435294Abstract: Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.Type: GrantFiled: December 9, 2009Date of Patent: May 7, 2013Assignee: Cayenne Medical, Inc.Inventors: Kenneth D.
