Patent number: 8192490Abstract: 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 bone, 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: January 26, 2011Date of Patent: June 5, 2012Assignee: Cayenne Medical, Inc.Inventors: Kevin N. Baird, Derek J. Harper, Joe P. Kovalski, Joanne Kovalski, legal representative, Kenneth D. Montgomery

Publication number: 20110282449Abstract: 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: ApplicationFiled: May 19, 2011Publication date: November 17, 2011Applicant: CAYENNE MEDICAL, INC.Inventors: Kenneth D.

Publication number: 20110184438Abstract: An adjustable, stand-alone tensioning system requires no additional fixturing, weights, or bone surface modification, and allows a single practitioner to provide an adjustable and repeatable tension to a soft tissue graft, and to install the final fixation implant. Its design facilitates introduction of the suture component of the graft into the tensioning process by simplifying retention of the suture. An even, regulated and reproducible tension is easily achieved without requiring the practitioner to manually pull on the suture strands to maintain graft tension.Type: ApplicationFiled: January 27, 2011Publication date: July 28, 2011Applicant: CAYENNE MEDICAL, INC.Inventor: Jordan A.

Publication number: 20100256657Abstract: A system and method for repairing soft tissue comprises introducing an instrument having a shaft into an operative site, such as a human shoulder. Then, a flexible grasper is advanced from the instrument to capture a portion of soft tissue. The flexible grasper is then retracted so that the captured tissue lies in a pathway for a needle in the instrument. The needle is advanced along the pathway through the captured tissue, and then a portion of suture is captured with the needle, distally of the captured tissue. The needle is retracted proximally through the captured tissue, to thereby pass the suture therethrough and plicate the tissue. The plicated tissue is then released from the grasper.Type: ApplicationFiled: April 5, 2010Publication date: October 7, 2010Applicant: CAYENNE MEDICAL, INC.Inventor: Nicanor A. Domingo

Publication number: 20100152850Abstract: 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: ApplicationFiled: December 9, 2009Publication date: June 17, 2010Applicant: CAYENNE MEDICAL, INC.Inventors: Kenneth D.

Publication number: 20100137887Abstract: Devices, systems and methods are disclosed for repairing soft tissue. The surgical system allows for the creation of tissue repair by grasping, aligning and sewing or fixing tissue. For example, this system may be used for clipping together excessive capsular tissue and reducing the overall capsular volume. The deployment device includes a central grasping mechanism and an outer clip delivery system. The clip embodiments may be single or multi-component (penetration and locking base components) that penetrate tissue layers and deploy or lock to clip the tissue together. An example of the system is used to reduce the joint capsule tissue laxity and reduces the potential for subluxation or dislocation of the joint by either restricting inferior laxity (anterior or posterior) and resolving or eliminating pathologic anterior or posterior translation.Type: ApplicationFiled: November 19, 2009Publication date: June 3, 2010Applicant: CAYENNE MEDICAL, INC.Inventors: Heber Crockett, John Wright, James G.

Publication number: 20100114123Abstract: A system for transdermal repair of soft tissue includes an instrument comprising a proximal actuator portion, a fixed needle having a lumen and extending distally from the proximal actuator portion, and a movable needle having a lumen and extending distally from the proximal actuator portion. The movable needle is movable axially between an advanced position and a retracted position relative to the proximal actuator portion. A suture needle is disposed within the lumen of one of the fixed and movable needles, and has a length of suture connected thereto. Needle graspers are disposed in the lumen of each needle, for securing the suture needle and assisting in the transfer of the suture needle from one needle to the other to complete a suture passing step.Type: ApplicationFiled: October 22, 2009Publication date: May 6, 2010Applicant: CAYENNE MEDICAL, INC.Inventor: Kevin S.

Publication number: 20100004683Abstract: A method for securing suture to bone comprises drilling a hole in a desired portion of bone at a desired procedural site, passing a strand of suture through a portion of soft tissue to be approximated to the portion of bone, and extending the free suture ends proximally from the soft tissue. The suture is loaded into an anchor implant. Using an inserter, on a distal end of which is attached the anchor implant, the anchor implant is manipulated into the bone hole. The suture is then tensioned to a desired level by pulling on the free suture ends, after the anchor implant is positioned in the bone hole. The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.Type: ApplicationFiled: December 31, 2008Publication date: January 7, 2010Applicant: CAYENNE MEDICAL, INC.Inventors: Jordan A. Hoof, Kevin S.
