IMPLANT AND FILAMENT MANAGEMENT DEVICE
A variety of configurations of implant management devices are provided. The configurations provide different combinations of features for maintaining a location of an implant with respect to the device and managing filaments of the implant. One exemplary embodiment of a device includes a generally rectangular-shaped body having an implantable body retainer, an opening disposed a distance apart from the retainer and configured to receive a ligament graft therein, and a fold extending across the body and intersecting the opening. Folding one end of the body towards a bottom surface of the body along the fold can form a filament loop engaging region to hold in tension a filament loop extending from the implant. Additional filament(s) associated with the implant can be managed by various filament retention features. Methods for preparing a ligament graft for implantation by relying upon indicia formed on a surface of the device body are also provided.
Helicoil interference fixation system for attaching a graft ligament to a bone
A helicoil interference fixation system comprising: a helicoil comprising a helical body comprising a plurality of turns separated by spaces therebetween, the helical body terminating in a proximal end and a distal end, and at least one internal strut extending between at least two turns of the helical body; and an inserter for turning the helicoil, the inserter comprising at least one groove for receiving the at least one strut; the helicoil being mounted on the inserter such that the at least one strut of the helicoil is mounted in the at least one groove of the inserter, such that rotation of the inserter causes rotation of the helicoil.
TENSIONABLE AND LOCKABLE MICRO SUTURE ANCHORS AND ANCHOR ARRAYS FOR ANATOMICAL ATTACHMENT OF SOFT TISSUE TO BONE
A toggle-type suture anchor that incorporates individual suture tensioning and locking without knot tying. The anchor includes several exemplary designs of toggle bodies having a working suture pre-threaded through one or more passages therethrough. A locking suture loop is pre-threaded relative to the working suture and includes a collapsible loop that encircles a portion of the length of suture running longitudinally adjacent the side of the anchor. With the loop open, the working suture can slide through the anchor, however, when the loop is closed the working suture is locked in position to retain tension on the working suture. Alternatively, the locking suture loop can be replaced with a mechanical locking member that moves from a first unlocked to a second locked position. The exemplary anchors can be utilized in a pre-strung connected array of anchors.
METHOD AND APPARATUS FOR CREATING A SEAM-LIKE ANATOMICAL LOW CREEP ATTACHMENT OF SOFT TISSUE TO BONE
Methods and apparatus for creating a seam like array of suture stitches joined in series by sequential anchors in bone. The anchors are transtendon implants positioned through the tendon in the original tendon footprint and each array includes four or more anchors. The seam like array extends across at least a portion of the tendon. The stitches can extend generally perpendicular to the direction of the tendon orientation. In rotator cuff repair, the anchors are positioned in the original footprints of the infraspinatus and/or supraspinatus tendons and the seam like array extends in an anterior to posterior direction across the particular tendons torn and repaired. The entire array of anchors can be positioned in the medial half of the original footprints.
INDIVIDUALLY LOCKABLE CINCH LOOP MICRO SUTURE ANCHOR ARRAY FOR HIGH DENSITY ANATOMICAL ATTACHMENT OF SOFT TISSUE TO BONE
A system of toggle type suture anchors is disclosed. The plurality of suture anchors is connected in series by a plurality of independently cinchable working suture loops with one working suture loop connecting each pair of anchors in series to form a chain. Each of the suture anchors as connected by working suture loops allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a loop type locking mechanism to lock the cinchable working suture loop subsequent to tensioning so that the loop remains fixed in size during cyclic loading during joint use. This creates an independently tensioned suture stitch between each implanted suture anchor and the just previously implanted anchor. In total the system as implanted creates a high density, continuous array of anchor-to-anchor stitches for robust securement of soft tissue to bone.
REINFORCED KNEE METHOD AND APPARATUS
An anchor for anchoring tensile members to bone includes: a housing having a hollow interior; a collet in the interior of the housing, having a central bore for accepting tensile members therethrough and an exterior surface, wherein the collet is configured to be swaged around the tensile members; a sleeve having opposed interior and exterior surfaces, the sleeve disposed in the hollow interior of the housing and positioned adjacent to the collet, so as to be movable between first and second positions; wherein at least one of the exterior surface of the collet and the interior surface of the sleeve is tapered and the sleeve and the collet are arranged such that movement of the sleeve from the first position to the second position will cause the collet to swage radially inwards around the tensile members; and a flange element, wherein the housing is pivotally mounted to the flange element.
SYSTEM AND METHOD FOR REPAIRING A LIGAMENT
A surgical kit for repairing a ligament includes suture tape configured to be positioned across the ligament from a fixed end of the ligament to a free end of the ligament. At least one anchor is configured to position over the ligament. An instrument is configure to secure the anchor to the bone.
DEVICES AND METHODS FOR STABILIZING TISSUE AND IMPLANTS
An implant for repairing a joint between a first bone and a second bone includes a first section constructed of a substantially rigid material and a graft constructed of soft tissue having a first end and a second end. The first section has a first end surface configured for positioning against the first bone. The graft is configured for stabilizing the first section relative to the first bone. A first fastener is configured for mounting to the graft and the first section to anchor the graft to the first section. A second fastener is configured for mounting to the graft and the first bone to anchor the graft to the first bone.
DEVICES, SYSTEMS, AND METHODS FOR REPAIRING SOFT TISSUE AND ATTACHING SOFT TISSUE TO BONE
Devices, systems and/or methods for repairing soft tissue adjacent a repair site. In one embodiment, a repair device includes a plate member and an anchor. The plate member having a periphery, the plate member configured to be positioned along an outer surface of the soft tissue. The anchor includes a base and six legs extending from the base, the six legs extending from the base being moveable to a curled configuration such that the six legs wrap around separate portions of the periphery of the plate member with the soft tissue therebetween. In this manner, the repair device may be anchored to the soft tissue.
SOFT TISSUE-HARD TISSUE INTERFACE FIXATION DEVICE
Devices and methods for joining a first and second tissue in a patient are disclosed that include a base with opposed first and second surfaces, and a plurality of recurved tines oriented to a tine axis and extending from the first surface of the base. The base defines four suture holes extending through the first and second surfaces of the base and configured to receive at least one suture passing between the first and second surfaces of the base. The plurality of recurved tines provides unidirectional traction of the first tissue along the tine axis toward the first surface to secure the device to the first tissue. The device is secured to the second tissue at the second surface with the at least one suture secured to at least one anchor secured to the second tissue.
