Method of performing a tendon replacement
A suture assembly, including a button having two apertures and a suture defining a lumen and forming a double loop, formed by a double trap formed in the suture, opposed to the button, and in which a first portion of the suture is threaded through the lumen of the double trap and a second portion of the suture is also threaded through the lumen of the double trap, so that two portions of suture are positioned together in the double trap. The first portion of the suture, after emerging from the double trap, is threaded through the lumen again, thereby forming a second trap, increasing resistance of the double loop to expansion, the double loop being threaded through the apertures of the button, the suture having two suture ends that are threaded through the button apertures and accessible on a side of the button opposed to the double loop.
Graft fixation screw with tangs
The graft fixation device with tangs combines a fixation screw body with tangs that extend from an internal position to an external position, the tangs piercing and gripping the bone and the graft. The use of tangs overcomes the prior art limitations of relying exclusively on compression, which increased the risk of failure, including failure modes such as the graft sliding out of the hole.
ANCHOR INSERTION SYSTEMS FOR A WINGED BONE ANCHOR HAVING A DRIVING CORE
The present disclosure provides new and innovative bone anchors and bone anchor insertion systems that enable smaller bone holes by eliminating the need for a cannula to transport the bone anchor. The provided bone anchors and insertion systems also help prevent damage to suture used in a bone anchor insertion procedure. The bone anchor includes a securement portion that surrounds a core portion. The securement portion includes multiple wings that are shape-set to be splayed outward from the core portion, though may be bent towards or away from the core portion in response to an applied force. The core portion includes a rod extending from a head. The rod includes a drive feature such that a surgeon may engage an inserter with the rod to drive the bone anchor through a bone hole. The bone hole walls maintain the bone anchor in a compressed state.
SYSTEM AND METHOD FOR SECURING TISSUE TO BONE
Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue anchoring device is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and inside surfaces of a bone tunnel to secure the tissue within the tunnel. Methods are described that enable use of the bone anchoring device to secure a tissue graft into the tibial and femoral bones during anterior cruciate ligament (“ACL”) reconstruction.
Devices and methods for anchoring tissue
Devices and methods for anchoring soft tissue, tissue grafts, and the like to a bone are provided. In one example, an assembly includes a suture anchor, suture, and inserter. In another example, a method provides for reattaching soft tissue to a bone.
One-way adjustable loop suture constructs and methods of forming and using the same
Surgical constructs and methods include the use of a one-way adjustable fixation loop that is formed by tying two knots in a surgical filament, each knot defining an individual adjustable loop and the individual adjustable loops being interconnected to form the one-way adjustable fixation loop. The knots enable a non-spliceable suture to be used in the creation of the one-way adjustable fixable loop. Embodiments can include a fixation device, such as a cortical button or plate for use in a bone tunnel, and enable the knots to work independent of and suspended below the fixation device. Embodiments can increase the compatibility of the adjustable fixation loop with existing fixation devices and can isolate and protect the knots from damage during use and after implantation.
TENDON REPAIR ANCHOR
The present disclosure provides a tendon repair anchor. An anchor plug is inserted into an anchor receptacle seated in a bone of a graft recipient. Sloped protrusions on the anchor plug interact with protrusions in the anchor receptacle to secure the anchor plug within the anchor receptacle and generally allow movement in a direction that more tightly secures the tendon graft to the bone. By allowing such unidirectional movement, slack in the sutures that secure the tendon graft to the anchor plug will not prevent the tendon graft from being properly positioned relative to the bone. Proper placement of the tendon graft allows for better healing and improves the likelihood of proper tendon replacement and tensioning.
Tissue fixation system and method
A tissue fixation system is provided for dynamic and rigid fixation of tissue. A fastener connected with an elongate fastening member, such as a cable, wire, suture, rod, or tube, is moved through a passage between opposite sides of tissue. A medical device is used to secure the fastener to the elongate fastening member. The medical device includes a tensioning mechanism for tensioning the elongate fastening member. As crimping mechanism is used to secure the fastener to the elongated member, where a cutting mechanism cut the excess portion of the elongated member.
COMBINATION THERAPY FOR TISSUE REPAIR
A system for the repair of a ruptured tissue is provided. Aspects of the invention include a repair device comprising a combination of a scaffold and graft attached by one or more sutures to one or more fixation devices and inserted into a repair site via arthroscopic equipment or an open surgical procedure. The system may be used to treat tissue injuries including ruptured ligaments, tendons, and cartilage.
Method and apparatus for coupling soft tissue to a bone
A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. A collapsible tube is positioned about the suture Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel and the collapse of the tube to form an anchor.
