A suture anchor assembly includes a main suture strand, a plurality of suture arms, and a plurality of suture anchor elements connected to the main suture strand by a suture arm. The suture anchor elements are configured to rest against a cortex of a bone to provide an anchor when they are in a deployed configuration. The suture anchor assemblies can be employed in place of or in addition to traditional suture anchors. The assemblies, kits, and methods described herein can be utilized in a variety of procedures and locations in the body where anchoring a graft or tissue adjacent a bone is desired, including, for example, rotator cuff repair and ligament (e.g., the anterior cruciate ligament or ACL) reconstruction and/or repair.

Self-assembling suture anchor assembly, surgical kit, and surgical repair method

A suture anchor, and a surgical filament assembly using same, capable of being fixated in a hole formed in a bone of a patient. The suture anchor preferably includes an anchor body having a distal end, a proximal end, a passage extending from the proximal end toward the distal end, at least one feature disposed on the exterior of the anchor to engage bone, and a filament knot patency element disposed within the passage and defining a channel having a sufficient minimum cross-sectional area to allow movement of a portion of a surgical filament therethrough when a removable sliding knot is formed, using the surgical filament, about the filament knot patency element. The surgical filament assembly preferably includes a first filament having a sliding knot removably positioned about the knot patency element, with a shortening limb and a tightening limb each extending from the sliding knot. The sliding knot defines an adjustable capture loop having two legs extending proximally to a bight, one leg transitioning into the shortening limb and passing through the channel of the knot patency element, the shortening limb being accessible to enable a user to shorten the capture loop. The tightening limb enables the user to tighten the sliding knot against an object extending through the capture loop to secure the object to the anchor.

Surgical filament assemblies

A buckle useful for cortical fixation has a graft retention loop slidably affixed thereto for movement from a first position adjacent a first end of the buckle to a second position at about the midpoint of the buckle. The buckle, with a graft over the loop, is drawn up lengthwise through a bone tunnel through a tibia and then flipped sideways to rest against the surface of the bone with the loop and graft depending back into the tunnel. The sliding attachment of the loop permits flipping of the buckle minimizes the flipping distance, which is the excess amount of the loop which must be pulled free of the tunnel to allow the buckle to be flipped sideways.

Flipping-type graft fixation device and method

A suture anchor, and a surgical filament assembly using same, capable of being fixated in a hole formed in a bone of a patient. The suture anchor preferably includes an anchor body with a passage extending from a proximal end toward a distal end, and at least one bone engaging feature on the exterior of the anchor. A knot patency element disposed within the passage holds a removable sliding knot formed, using the surgical filament. A tightening limb of the sliding knot enables the user to tighten the sliding knot against an object extending through a capture loop to secure the object to the anchor.
