Abstract
A soft anchor, anchor assembly, and methods of inserting soft anchors into bone are disclosed herein.
Claims16
A soft anchor, comprising:
- a single one-piece sheath including opposite distal and proximal ends, a lumen having a length that forms a longitudinal portion of the sheath, and at least one bifurcation bifurcating the sheath into first and second bifurcated portions at or near the distal end of the sheath, such that the bifurcation is located between the lumen and the first and second bifurcated portions;
- and
- at least one flexible strand received in the sheath, the at least one flexible strand including a first segment, a second segment, and a loop segment located therebetween, wherein the first segment passes through the length of the lumen, the loop segment continuously passes through respective passageways of the first and second bifurcated portions of the sheath, and the second segment passes through the length of the lumen with the first segment,
- wherein at least a portion of each of the first and second segments of the at least one flexible strand extends from the lumen at the proximal end of the sheath outside of the sheath and
- wherein the first and second bifurcated portions are connected to form a sheath loop at the distal end of the sheath, the sheath loop having a first dimension when the at least one flexible strand is not tensioned, the sheath loop having a second dimension greater than the first dimension when the at least one flexible strand is pulled to gather the sheath loop around the loop segment of the at least one flexible strand to form a sheath bundle.

A soft anchor assembly, comprising:
- an instrument;
- a single one-piece sheath including opposite distal and proximal ends, a lumen having a length that forms a longitudinal portion of the sheath, and at least one bifurcation bifurcating the sheath into first and second bifurcated portions at or near the distal end of the sheath, such that the bifurcation is located between the lumen and the first and second portions;
- and
- at least one flexible strand received in the sheath, the at least one flexible strand including a first segment, a second segment, and a loop segment located therebetween, wherein the first segment passes through the length of the lumen, the loop segment continuously passes through respective passageways of the first bifurcated portion and the second bifurcated portion of the sheath, and the second segment passes through length of the lumen with the first segment,
- wherein at least a portion of each of the first and second segments of the at least one flexible strand extends from the lumen at the proximal end of the sheath outside of the sheath and
- wherein the first and second bifurcated portions are connected to form a sheath loop at the distal end of the sheath, the sheath loop having a first dimension when the at least one flexible strand is not tensioned, the sheath loop having a second dimension greater than the first dimension when the at least one flexible strand is pulled to gather the sheath loop around the loop segment of the at least one flexible strand to form a sheath bundle.

A method of installing a soft anchor into bone:
- forming a hole in the bone;
- inserting the soft anchor into the hole, the soft anchor comprising a sheath and a flexible strand received in the sheath, the flexible strand including a first segment, a second segment, and a loop segment located therebetween, wherein both the first and second segments of the flexible strand pass through a lumen of the sheath and the loop segment continuously passes through respective passageways of bifurcated first and second portions of the sheath wherein the first and second bifurcated portions are connected to form a sheath loop at a distal end of the sheath, the sheath loop having a first dimension when the at least one flexible strand is not tensioned;
- and
- pulling portions of the flexible strand that extend outside of a proximal end of the sheath to gather the sheath around the loop segment of the flexible strand to form a sheath bundle to secure the soft anchor to the bone in the hole the sheath bundle has a second dimension greater than the first dimension.
