Method and Device for Ligament Reconstruction
A device for stabilizing a soft tissue graft to a fixation device for ligament reconstruction, including a generally planar and rectangular elongate pad of woven suture material having a proximal portion with an upper edge and upper corners and a distal portion having a bottom edge, wherein said proximal portion transitions into two integral, generally cylindrical suture limbs extending from the upper corners, each of which transition into and terminate in a distal end configured to fit through the eye of a surgical needle. A method of attaching the device to a tissue graft is also described. The device facilitates rapid fixation of the soft tissue graft in such a way as to avoid creep and laxity of the final construct.
SYSTEMS AND METHODS FOR LIGAMENT GRAFT PREPARATION
Systems and methods for preparing a ligament graft for a ligament reconstruction procedure are provided. In general, the described techniques utilize a graft preparation system having a holder and a delivery suture assembly removably coupled thereto. The delivery suture assembly can include a spine coupled with an anchor suture configured to form a self-tightening knot used to position the assembly around a graft and a plurality of suture windings configured to be affixed to the graft when the assembly is deployed. The assembly is delivered to the graft using the holder and the sutures can be affixed to the graft without penetrating therethrough. The spine helps to evenly distribute the load among the windings compressing the graft which are thus are capable of withstanding increased loads. Thus, an improved, simplified, and time- and labor-saving approach to preparing ligament grafts is provided.
Methods of making reinforced soft tissue grafts with suture loop/needle constructs
A method of reinforcing a biological construct according to an exemplary aspect of the present disclosure includes, among other things, attaching a suture loop/needle construct to a reinforcement material and stitching the reinforcement material to a biological construct to form a reinforced biological construct. The reinforcement material is attached to the suture loop/needle construct prior to approximating the reinforcement material to the biological construct.
METHOD AND APPARATUS FOR FORMING A SELF-LOCKING ADJUSTABLE LOOP
An apparatus can include a first flexible member having first and second ends and a first body extending therebetween that defines a first passage portion. A second flexible member can include first and second ends and a second body extending therebetween that defines a second passage portion. The first end of the first flexible member can pass into and through the second passage portion in a first direction such that the first end extends outside of the second passage portion. The first end of the second flexible member can pass into and through the first passage portion in a second direction such that the first end of the second flexible member extends outside of the first passage portion to form a self-locking adjustable flexible member construct. Applying tension to the first ends can draw the passage portions and corresponding second ends toward each other.
Modular Gap Balancing Block
A method of preparing a femur for receipt of a prosthesis, includes selecting an assessment device from a plurality of devices, each of the devices include first and second contact surfaces positioned at different elevations from a bottom surface of the device; inserting the device into a knee joint such that the bottom surface of the device contacts a resected surface of a tibia, the first contact surface contacts a first condylar surface, and the second contact surface contacts a second condylar surface, the first and second contact surfaces have a fixed relationship relative to the bottom surface while disposed within the joint; determining a condylar angle of a condylar axis defined by the first and second condylar surfaces based on a known offset distance between the first and second contact surfaces; and resecting the first and second condylar surfaces along a plane based on the condylar angle.
Tissue fixation system with auxiliary plate
A tissue fixation system provides a primary fixation plate with a depending graft retention loop and a longer auxiliary fixation plate which fits to the primary fixation plate via upwardly projecting pegs which fit into suture holes in the primary fixation plate. The system has particular utility in cortical fixation procedures in which a graft channel is over-drilled and a longer fixation plate is indicated.
METHOD AND APPARATUS FOR COUPLING ANATOMICAL FEATURES
A method of coupling a first portion of an anatomy to a second portion of the anatomy includes coupling first and second bones of the anatomy with a bone-tendon-bone implant. The bone-tendon-bone implant has a first bone end, a second bone end and a replacement tendon between the first and second bone ends. The first and second bone ends are positioned in corresponding first and second bores of the first and second bones. The first bone end is secured to the first bone with a first bone anchor. A second anchor coupled to the bone-tendon-bone implant is passed through and outside the second bore. The second anchor is coupled to an adjustable suture construct having two adjustable suture loops. Tensioning at least one of first and second ends of the adjustable suture construct tensions the replacement tendon and positions the first bone relative to the second bone.
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.
Method and apparatus for coupling anatomical features
A method of coupling a first portion of an anatomy to a second portion of the anatomy includes coupling first and second bones of the anatomy with a bone-tendon-bone implant. The bone-tendon-bone implant has a first bone end, a second bone end and a replacement tendon between the first and second bone ends. The first and second bone ends are positioned in corresponding first and second bores of the first and second bones. The first bone end is secured to the first bone with a first bone anchor. A second anchor coupled to the bone-tendon-bone implant is passed through and outside the second bore. The second anchor is coupled to an adjustable suture construct having two adjustable suture loops. Tensioning at least one of first and second ends of the adjustable suture construct tensions the replacement tendon and positions the first bone relative to the second bone.
Prosthetic Devices
Expandable prosthetic devices used for treating a variety of conditions, including rotator cuff injuries, broken and/or depressed bone fractures, infection and/or inflammation in the body. In one embodiment, a prosthesis includes an implant having a pressure regulating valve. The implant is capable of being positioned between a first tissue and an opposing second tissue in a void space and of deforming under pressure in response to articulation of a joint. The pressure regulating valve is configured to open based on a predetermined pressure in the implant.
