Abstract: 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.

Abstract: An anchor construct having an anchor having a length of suture material passing therethrough, the suture material having a loop strand terminating at a first end and a post strand terminating at a second end, a splice loop formed by first end, a sliding construct formed by the first end and the second end, wherein the sliding construct is configured to adjust the relative position of the splice loop and the anchor. The anchor construct can be deployed by passing the first end through a first body and through the splice, creating a locking loop of a first size around the first body, implanting the anchor into a bone hole, pulling the post strand to decrease the perimeter of the positioning loop to a second size smaller than the first size, and pulling the loop strand to decrease the perimeter of the locking loop to a smaller second size.

Abstract: A power delivery approach for delivering power to an electrosurgical vessel sealer when the jaws of the sealer surround tissue to be desiccated. Power delivery commences at a starting point that is at least 40 Joules and then decreases over a first predetermined period of time to a predetermined minimum power level to provide approximately 15 Joules in total. When the predetermined minimum power level is reached, power is then continuously increased over a second predetermined period of time to fully desiccate the tissue. Power delivery is terminated prior to over-desiccation of the tissue.

Abstract: An articulating suture hook for passing or retrieving suture. The suture hook having a handle with a proximal end and distal end. A stiffening tube is fixed to the distal end of the handle extending distally from the handle. A flexible outer tube is fixed to the stiffening tube and extends distally therefrom. A cut portion of the flexible outer tube has a plurality of cuts positioned therealong. In a first configuration, the flexible outer tube extends parallel to or in alignment with the stiffening tube, but in a second configuration, the flexible outer tube is curved at the cut portion. The plurality of cuts may be arranged into two patterns. Each cut arranged in a first pattern is offset at an angle from each cut arranged in a second pattern. The pattern, shape, and size of the cuts determines the movement of the flexible outer tube to the second configuration.

Abstract: Methods and devices for securing soft tissue to a rigid material such as bone. A tissue capture anchor 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 spreader and inside surfaces of a bone hole to secure the tissue within the hole. A bone anchor is described that comprises an anchor body with expandable tines and a spreader that expands the tines into bone. The spreader captures tissue via a suture loop at the distal end of the bone anchor. Also described is an inserter that can be used to insert the anchor into bone and move the spreader within the anchor to expand the anchor and capture the tissue between the anchor and the bone. Methods are described that allow use of single bone anchor to secure tissue to bone or also to use more than one bone anchor to provide multiple lengths of suture material to compress a large area of soft tissue against bone.
