TISSUE GRAFT FIXATION WITH TENSION ADJUSTMENT
Apparatus for tissue graft fixation. A tissue graft fixation device includes a main body part (15) provided with a pair of suture through holes (20, 25) positioned on opposite sides of a spherically radiused screw through hole (30), the pair of suture through holes sized to receive sutures, the spherically radiused screw through hole sized to receive a radiused head of a securing screw, and two spike parts (35, 40) extending substantially parallel to each other from an underside of the main body, the spike parts spaced apart at a predetermined distance slightly shorter than a diameter of a formed bone tunnel and adapted be stricken into a bone.
Shape memory polymer
A polymer is composed of a linear chain acrylate and a multi-functional acrylate cross-linker. The polymerized composition exhibits a transition at a temperature between about 34° C. and about 50° C. The polymerized composition exhibits shape memory effects. In one embodiment, the linear chain is tert-butyl acrylate and the crosslinker is polyethylene glycol dimethacrylate. The resultant shape memory polymers may be used in medical devices to provide devices with different shapes for pre and post implantation.
Syndesmosis treatment construct
An apparatus and method are provided for a syndesmosis treatment construct configured to be placed into a cinched configuration that presses a first bone against a second bone. The syndesmosis treatment construct comprises a proximal fixator to contact the first bone and a distal fixator to contact the second bone. A first suture and a second suture are parallelly looped through the proximal fixator and oppositely looped through the distal fixator. Distal ends of the first and second sutures are fixated within a washer disposed between the proximal fixator and the first bone. Proximal ends of the first and second sutures are passed through openings in the washer and through the proximal fixator. Pulling of the proximal ends by a practitioner places the syndesmosis treatment construct into a cinched configuration. Any of various suitable suture knots may be formed so as to fixate the cinched configuration.
Methods and devices for forming bone tunnels
Methods and devices are provided for forming bone tunnels. In general, the methods and devices allow multiple converging tunnels to be formed in bone, such as in an arthroscopic surgical procedure, e.g., a rotator cuff repair surgical procedure. One or more sutures can be advanced through the converging tunnels, and the suture(s) can be coupled to tissue. The suture(s) with the tissue coupled thereto can be tensioned, thereby helping to maximize an amount of the tissue in contact with the bone. In an exemplary embodiment, a guide device is provided that can be configured to allow a first tunnel to be formed in bone and to allow a plurality of additional tunnels to be formed in the bone at predetermined angular positions relative to the first tunnel such that each of the additional tunnels can extend transverse to the first tunnel and intersect the first tunnel.
Methods, systems, and devices for gauging a bone tunnel
Devices, systems, and methods are provided for gauging a bone tunnel. In one exemplary embodiment, a graft repair system can include an elongate pin, an elongate pusher shaft configured to be positioned over one opposed end of the pin when the pin is positioned within a bone tunnel, and a gauge member configured to be positioned over another opposed end of the pin when the pin is positioned within the bone tunnel. When the pusher shaft abuts the bone adjacent one of the open ends of the bone tunnel and the gauge member abuts the bone adjacent the other open end of the bone tunnel, an indicator mark on the pin can be visible through one or more windows formed in the gauge member. The indicator mark's position relative to each of the one or more windows can indicate one or more characteristics related to the bone tunnel.
Adjustable and fixed assembled bone-tendon-bone graft
The present invention has multiple aspects relating to a bone-tendon-bone graft and components thereof. Embodiments of the present invention comprise an intermediate bone block that is used to adjustably secure soft tissue (e.g., tendon) in a patient. The present invention further relates to an assembled bone-tendon-bone graft suitable for implantation in humans comprising the intermediate bone block and a length of soft tissue. In a preferred embodiment, a bone-tendon-bone graft comprises a length of soft tissue (e.g., tendon) extending from a first assembled bone block to a second bone block and then doubles back to said first assembled bone block. Depending upon the embodiment, the second bone block fixedly or slideably attaches to the length of soft tissue and facilitates it doubling back to the first assembled bone block.
Single tunnel, double bundle anterior cruciate ligament reconstruction using bone-patellar tendon-bone grafts
Anterior cruciate ligament reconstruction methods and devices are designed to achieve an anatomically accurate double bundle anterior cruciate ligament reconstruction by using a single femoral and tibial tunnel. The method and devices reconstruct the two bundles of the anterior cruciate ligament in a single femoral and tibial tunnel using a bone-patellar tendon-bone graft. The methods and devices enable an accurate anatomical reconstruction of the anteromedial and posterolateral bundles by creating a single femoral and tibial tunnel as opposed to creating two tunnels in the tibia and femur.
Arthroscopic tenodesis tool
An arthroscopic tenodesis kit, includes a guide including an elongate member having a length with a distal portion having one or more spring arms configured to open toward a free end of the distal portion of the guide to directly and releasably engage a tendon. The kit also includes an inserter having an elongate cannulated body having an interior bore having a blind end and an open end configured to slidingly receive the guide. The body of the inserter has a length that is shorter than the length of the guide, so that the distal portion of the guide remains spaced from the bore when the guide is fully received within the bore.
Method and apparatus for attaching soft tissue to bone
A repair system including at least one anchor, screw, or plate with a body and a suture capture element formed in the body for attaching at least one suture to the anchor, screw, or plate. The suture capture element being configured so as to permit the suture to be snared by the suture-capture element after the anchor, screw, or plate has been attached to bone.
Apparatus and method for repair of disruptions between bones
An apparatus and method for the repair of disruptions between bones. The apparatus defines a combination of sleeves, strands and crimps are provided to secure the bones, using a dual sided drill guide to prepare the bones for installation of the apparatus, which is adjusted upon installation to suit the appropriate alignment and tension of the apparatus. The method includes the preparation of the bones, the installation of the apparatus and the adjustment of the apparatus to properly align and tension the apparatus for repair of the bone.
