Adjustable fixation device
An adjustable fixation device includes a cleat portion and a suture portion, where the suture portion has a loop portion and a suture tail. Pulling on the suture tail places in tension a graft coupled to the loop portion. The suture is arranged to convey a mechanical advantage so that substantial force can be readily and controllably applied to the graft.
Multifilaments with time-dependent characteristics, and medical products made from such multifilaments
The invention relates to a resorbable multifilament comprising a number of individual resorbable filaments of a first type having a first degradation time and a number of individual resorbable filaments of a second type having a second degradation time, wherein the filaments of the first type and the filaments of the second type are arranged in close relationship to form a composite multifilament having a length and a specific composite cross-section comprising cross-sections of the individual filaments of the first type and second type, wherein the cross-sections of the individual filaments of the first and second type are located at determined relative positions, wherein the relative positions amongst the individual cross-sections of the filaments of the first and second types are invariant over the length of the composite multifilament.
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.
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.
Slack removal in suture constructs for tissue repair
Utilities (e.g., systems, methods, etc.) for reducing or limiting slack in stitching or suture constructs secured to tissues in a manner that limits the need for surgeons to physically pull on patients' muscles to remove such slack and that may ultimately reduce recovery time for patients. In one aspect, a method of creating or anchoring a suture construct (e.g., a method of stitching) in tissue in a manner that produces first and second opposite portions of the construct that can be pulled apart in any appropriate manner to apply a tension in the construct to remove slack therein substantially free of pulling on patients' muscles to remove such slack is disclosed. The present utilities also describe a tool that can be used to automatically apply a predetermined level of tension to a suture construct to remove slack therein.

FLAT SURGICAL SUTURE CONSTRUCTS WITH LOOPS AND METHODS OF TISSUE FIXATION
Knotless surgical constructs and methods of tissue repairs. A surgical construct can offer both repair and shuttling capabilities to allow for a single pass to load multiple sutures at once. A surgical construct is in the form of a flat suture tape provided with reinforced perforations and/or shuttling loops that can pass or shuttle multiple repair sutures while making a single pass through or around soft tissue.

Constructs and methods for repairing a tendon with a reduced risk of reinjury
A method of effecting a tendon repair in a patient comprising providing a suture tape, using the suture tape to connect tendon tissue to bone of the patient such that the suture tape lays flat on the tendon, and permitting ingrowth of the tendon tissue into the suture tape as the absorbable fibers are absorbed into the patient's tissue. The suture tape is a flat braid of elastic, absorbable fibers and high strength fibers, the tape being at least 1 mm wide and 2 cm long, and less than 1 mm high. The suture tape includes at least 4 absorbable fibers and at least 4 high strength fibers. Further, the suture tape is capable of being stretched at least 10% from its shortest length to the length at which it breaks and is capable of withstanding a load of at least 260 Newtons before breaking.
