TRIANGULAR FIBROCARTILAGE COMPLEX RECONSTRUCTION TECHNIQUES
This disclosure is directed to methods for reconstructing an unstable triangular fibrocartilage complex (TFCC). Exemplary methods include preparing, delivering, and fixating a graft within a distal radioulnar joint in a manner that restores the functionality to the TFCC, thereby improving the joint kinematics of the radioulnar joint.
Tissue anchor assembly with an adjustment button
A tissue anchor assembly comprises a tissue anchor; a suture; and an adjustment button coupled with the suture. The adjustment button is adapted to adjust tension relative in the suture. When tension is applied to a second suture section trailing away from the tissue anchor, the adjustment button is engaged with the second suture section through locking splines and the adjustment button slides along a portion of the suture to increase a distance between the adjustment button and the tissue anchor. When tension is applied to a first suture section trailing away from the tissue anchor, the adjustment button moves in a direction towards the tissue anchor to reduce a distance between the adjustment button and the tissue anchor.
Tissue repair assembly
A tissue repair assembly for attachment of tissue to bone or tissue to tissue having a soft anchoring implant 100 with a length of suture 120 there through for tensioning the implant and facilitating attachment of other tissue. The implant 100 is a soft, flexible, three-dimensional structure that has a resident volume 200. An inserter tube 310 facilitates the placement of the implant 100 into bone or adjacent soft tissue where it may be deployed. Upon deployment, the soft anchoring implant 100 shortens axially and expands radially, achieving a larger diameter than the hole through which it was placed, thus resisting pull out.
Augmented suture construct for syndesmotic stabilization
A method includes forming a bone tunnel through a first bone and a second bone and inserting a flexible construct through the bone tunnel. The flexible construct includes a first anchoring element and a second anchoring element coupled by at least one flexible strand defining an adjustable loop. The at least one flexible strand includes a first end extending from the first anchoring element in an opposite direction from the adjustable loop. A length of the adjustable loop is adjusted to position the first bone and the second bone in a selected spacing. The first end of the at least one flexible strand is coupled to a tissue section using a third anchoring element.
ANCHOR APPARATUS
A clamp for anchoring tensile members includes: a collet having a peripheral wall defining a central bore for accepting tensile members therethrough and an exterior surface, wherein the collet is configured to be swaged around the tensile members, and includes an array of longitudinal grooves defining webs configured to collapse inward in response to external compressive force; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve positioned axially adjacent to the collet, so as to be movable parallel to a mutual central axis of the sleeve and the collet, between first and second positions; and wherein the sleeve and the collet are arranged such that movement of the sleeve from the first position to the second position will cause the interior surface of the sleeve to bear against the exterior surface of the collet, causing the collet to swage radially inwards around the tensile members.
Tap-in bone anchor with expanding ring
An anchoring device for holding suture in bone includes an implant body with a proximal end and a distal end. A distal opening of the implant body is configured to receive a first proximal portion of an anchor. An expandable ring is initially press-fit about the first proximal portion of the anchor. The anchoring device is then located in a pre-drilled bore in a bone portion and the anchor portion is drawn proximally into the implant body, causing the ring to expand and contact the inner walls of the bone bore thus providing additional locking force of the anchoring device in the bone.
KNOTLESS ANCHOR
Disclosed are devices, methods and/or systems for securing tissue to bone, including a suture anchor implant having a body through which a suture eyelet extends transversely, and one or more suture pinch slits extending proximally from the suture eyelet, the suture pinch slit(s) angled relative to the longitudinal axis of the anchor.
Biceps tenodesis implants and delivery tools
Methods and devices are provided for anchoring a ligament or tendon to bone. In one embodiment, a surgical implant is provided having a sheath and an expander that is received within the sheath. Various delivery tools, including a sheath inserter and a driver, are also provided. In use, the sheath inserter can be used to position a tendon within a prepared bone hole, and it can be used to deliver the sheath with a guidewire coupled thereto into the bone hole. The driver can be provided for delivering the expander into the sheath. A loader can optionally be used to load the driver and expander onto the guidewire coupled to the implanted sheath.
BICEPS REPAIR DEVICE
Methods and devices are provided for anchoring a ligament or tendon to bone. In general, various inserter tools are provided for simultaneously delivering an expandable sheath and an expander into bone. With both components of the implant mounted on the same tool, the sheath and a ligament can be advanced into a bone hole and the expander, which trails behind the sheath during delivery of the sheath, can be advanced into the sheath to expand the sheath and anchor the sheath and ligament within the bone hole.
Suture tape construct for providing anchor with non-sliding suture tape
A suture tape construct having a first section formed from a fibrous filament that extends from a first end to a second end and has a pair of a one-way protrusions extending therefrom. An anchor is positioned along the suture construct and, when the construct is deployed, is captured between the protrusions. The anchor may be a second section formed from braided suture material that is woven about the first section. The braided suture material can be deployed to form an all suture anchor while protrusions extending from the suture anchor proximately to the location of the deployed suture anchor prevent movement of the second section relative to the first section, thus forming a non-sliding suture tape anchored by the deployed braided material. The anchor may be a threaded anchor having an eyelet that is captured between the protrusions.
