Publication number: 20240050084Abstract: An anchoring system is a combination of a nanofiber scaffold material and an arthroscopically deployable suture anchor. The anchor is deployed into a bone tunnel using common techniques. The nanofiber material extends out of the proximal end of the implant, once deployed. The implant also includes pre-loaded sutures or has the ability to accept and lock sutures to the implant. For an implant pre-loaded with suture, the implant is placed into the bone, the material is deployed above the anchor onto the surface of the bone, suture is passed through the soft tissue, and knots are tied to secure the tissue against the bone, sandwiching the material between the bone and tissue, to provide a pathway for cells from the bone marrow to the soft tissue-bone interface, promote the healing response, provide a biomimetic structure that cells readily adhere to, and create a larger healing footprint.Type: ApplicationFiled: October 27, 2023Publication date: February 15, 2024Inventors: Kevin N. Baird, Derek J. Harper, Kevin S. Nason

Patent number: 11844510Abstract: A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (Thold). The inserter shaft is inserted into a hone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored. A further step involves actuating a control mechanism in the inserter handle to move the structure proximally to apply a second level of deployment tension (Tload) to the tensioning suture limb.Type: GrantFiled: March 8, 2021Date of Patent: December 19, 2023Assignee: Cayenne Medical, Inc.Inventors: Kevin S.

Patent number: 11730465Abstract: A self-adjusting suture construct can include a suture extending from a passive end to an active end. The passive end can include a first loop that the active end can be passed through to form a second loop. The active end can then be pulled to tighten the second loop around a portion of a patient's anatomy. The active end can be passed through an anchor and the anchor can be implanted to lock the tightened second loop.Type: GrantFiled: November 16, 2018Date of Patent: August 22, 2023Assignee: Biomet Manufacturing, LLCInventors: Nathan A.

Patent number: 11553907Abstract: A wicking component is integrated into an arthroscopically deployable bone anchor, and is intended to improve soft tissue-to-bone repair. Once deployed, the fibrous wick component extends from within the bone tunnel, out of the hole, and to the bone-tendon interface on the bone surface. The tissue is approximated against the bone, sandwiching the wick material between the bone and tissue. The wick component is ideally a polymeric fibrous or tissue-based scaffold that provides a pathway for cells (autologous bone marrow constituents and blood) to travel from within the bone to the soft tissue-bone interface, accelerating and promoting the healing response. The system provides a biomimetic structure that stimulates the extracellular matrix to encourage cell attachment and potentially improve the healing response. The wick component does not need to be integrated into a suture anchor and installed when the suture anchor is deployed.Type: GrantFiled: September 4, 2019Date of Patent: January 17, 2023Assignee: Cayenne Medical, Inc.Inventors: Kevin S.

Patent number: 11224417Abstract: A simple, threaded suture anchor is pre-loaded with suture in a configuration that allows a surgeon to compress tissue against the bone without tying a knot. The knot-tying step is replaced by a simple suture looping step which requires less time and is not prone to errors in knot tying technique. The suture anchor is a screw-in style anchor body. The suture is loaded into the anchor in a configuration that allows it to create a loop on top of the tissue after it has been passed through the tissue from bottom to top. The suture limbs are then loaded into a knotless anchor which is implanted off the lateral edge of the tissue. Tensioning of the suture limbs in the knotless anchor tightens the loop on top of the tissue, providing a fulcrum point of fixation over the pre-loaded suture anchor without the otherwise need for requisite knot tying.Type: GrantFiled: July 2, 2018Date of Patent: January 18, 2022Assignee: Cayenne Medical, Inc.Inventors: Kevin S.

Patent number: 11096681Abstract: An all-suture suture anchor system includes an all-suture anchor, an inserter, and a specially designed drill. The drill is used to enlarge the hole and create a pocket under the bone surface from the pre-drilled hole. The created pocket is intended to accommodate the expansion of the anchor when deployed into the bone, generating a true mechanical interference under the bone surface. The anchor is loaded on the inserter and placed at full length vertically inside the drilled hole. While holding the inserter on top of the drilled hole, so that a feature on the inserter keeps the anchor to a desired depth below the bone surface, tension is applied to the suture limb that is connected to the bottom end of the anchor. This tensioning step causes the length of the anchor to contract vertically and the anchor is simultaneously expanded circumferentially to fill the pocket previously created by the drill.Type: GrantFiled: March 28, 2018Date of Patent: August 24, 2021Assignee: Cayenne Medical, Inc.Inventors: Hoang P Nguyen, Derek J.

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.
