Method for coupling soft tissue to a bone
A method for coupling tissue with a flexible member including a tail and a self-locking construct coupled to the tail. The self-locking construct includes an adjustable first loop and an adjustable second loop coupled thereto. The method includes implanting an anchor in bone, the anchor slidably mounted to the tail. The tail is positioned relative to the tissue. An end of the tail is inserted through the first loop. The tail is passed through the first loop, the second loop is pulled into the anchor, and the self-locking construct is positioned relative to the tissue. The self-locking construct is tightened against the tissue by pulling on an end of the self-locking construct. The first loop is tightened onto the second loop.
TENSIONABLE AND LOCKABLE SOFT SUTURE ANCHORS AND ANCHOR ARRAYS FOR ANATOMICAL ATTACHMENT OF SOFT TISSUE TO BONE
Soft suture anchors are disclosed that can be formed into a pre-strung array with a common working suture. Each anchor includes the common working suture and a soft anchor member that is expandable when implanted. This allows first locking an individual anchor into a bone hole followed by tensioning the suture and independently locking the suture at the anchor. A first anchor is implanted through the tendon and the suture is locked. A second anchor is implanted a selected close distance from the first anchor, the working suture is tensioned between the first and second anchors, and the working suture is locked at the second anchor to create a single suture tensioned and locked stitch between the first and second anchor. This process is repeated for each anchor in the array.
Method and apparatus for coupling soft tissue to bone
A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. A bone engaging fastener is coupled to bone. A second fastener is coupled to a suture construction. The second fastener is coupled to the first fastener. Soft tissue is coupled to the suture construction.
Devices, systems, and methods for attaching soft tissue to bone tissue
A suture anchoring device for fixing a soft tissue to a bone tissue is disclosed that enables the exchange of sutures between anchors after implantation. The suture anchoring device may include a body that is inserted into the bone tissue, a suture exchange fitting situation within a passage formed within the body, and one or more pre-loaded sutures looped through the suture exchange fitting and projecting proximally from a proximal opening formed in the body. Surgical kits and surgical methods for performing various repair procedures using one or more suture anchoring device are also disclosed.
Locking suture construct
A locking suture construct having suture material with a first end and a second end, each attached to a first body in a slidable manner, a constricting member formed in the second end of the suture material, and a bight in the suture material between the first end and the second end. The bight can be pulled through the constricting member around a second body to create a locking loop. The first end and the second end are passed through the locking loop. Pulling the first end increases a perimeter of the locking loop and moves the constricting member toward the second body. When the constricting member reaches the second body, pulling the first end reduces the perimeter of the locking loop and moves/rotates the constricting member around the second body toward the first body to hold the first body in relative position to the second body.
Implant placement systems and one-handed methods for tissue fixation using same
Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments allow for the one-handed operation. To that end, embodiments in which relative axial movement between the inner tensioning device and outer driver device is optionally physically constrained, for example by means of cooperating and/or compressive elements disposed in the respective hub and handle portions, are described herein.
Knotless suture anchor with unthreaded nose
A suture anchor has a tubular body having an axial bore therethrough with one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole. These are preferably screw threads. A distal nose of the suture body has a smooth exterior surface. A length of suture passes down along the exterior surface over the purchase enhancements, over the distal nose, and up into the bore. The smooth exterior surface of the distal nose allows tension of the suture to be held by the engagement of the nose within the bone hole thus making it easier to obtain proper tension as the remaining portion is engaged into the bone hole to provide final fixation.
Knotless self-locking anchor constructs and methods of tissue fixation
Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with a fixation device, a flexible coupler and an optional shuttle/pull device attached to the flexible strand. An accordion-style weave region is formed by pulling on the shuttle/pull device subsequent to the fixation device being secured into the bone, to allow desired tensioning of soft tissue to be fixated or repaired relative to the bone and secured self-locking of the construct.
LOCKING SUTURE CONSTRUCT
A locking suture construct having suture material with a first end and a second end, each attached to a first body in a slidable manner, a constricting member formed in the second end of the suture material, and a bight in the suture material between the first end and the second end. The bight can be pulled through the constricting member around a second body to create a locking loop. The first end and the second end are passed through the locking loop. Pulling the first end increases a perimeter of the locking loop and moves the constricting member toward the second body. When the constricting member reaches the second body, pulling the first end reduces the perimeter of the locking loop and moves/rotates the constricting member around the second body toward the first body to hold the first body in relative position to the second body.
SUTURE ANCHOR
The present application relates to the field of medical devices, and in particular to a suture anchor. A suture anchor includes an anchor head and an anchor body, wherein a threading hole is formed on the anchor head, the anchor body includes a side pressing portion integrally formed by a plurality of layers of round tables, and at least two opposite longitudinal cuts are formed on each round table of the side pressing portion; from a direction close to the anchor head to a direction away from the anchor head, positions of the longitudinal cuts on adjacent round tables are deflected toward a same side.
