Systems, devices, and methods for securing tissue using hard anchors
First Claim
1. A surgical method, comprising:
- inserting an anchor having a plurality of bone-engaging features that extend radially outward from an outer wall of the anchor into a bone hole formed at a surgical site of a patient, the anchor having a proximal end, a distal end, and an axial bore extending from the proximal end to the distal end;
extending a repair filament through the axial bore, the repair filament having a first end, a second end, and an intermediate portion, the first and second ends extending proximal to the proximal end of the anchor and the intermediate portion forming a loop distal to the proximal end;
disposing a connecting filament located on the distal end of the anchor through the loop; and
distally advancing the anchor into the bone hole such that the connecting filament remains disposed between and in contact with the bone-engaging features and a sidewall of the bone hole, and the connecting filament is external to the bone-engaging features as the anchor advances through the bone hole.

Abstract
Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a device includes an anchor, a repair filament, and a connecting filament that is coupled to the repair filament, is in contact with the anchor'"'"'s distal end, and is effective to connect the repair filament to the anchor such that the repair filament slides with respect to the anchor. The anchor can be rigid, and can include an axial bore extending therethrough. At least one of the repair filament and the connecting filament can extend through at least a portion of the axial bore, and the bore can be sized such that a portion of the filament extending therethrough barely fits to help maintain the connection between the anchor, repair filament, and connecting filament. Embodiments of the systems and devices disclosed can be used in a number of methods for repairing soft tissue.

10. A surgical repair method, comprising:
-
forming an opening in a surgical site of a patient, the opening being defined by a sidewall; coupling a bone anchor having a proximal end, a distal end, and an axial bore defined therethrough to an insertion tool, the insertion tool having a proximal end, a distal end, and a lumen extending therethrough; extending a repair filament through the axial bore and the lumen, the repair filament being wrapped around a connecting filament at the distal end of the bone anchor, the connecting filament having a first end, a second end, and an intermediate portion, the intermediate portion being slidably engaged with the repair filament to connect the repair filament to the bone anchor; disposing a guide around the insertion tool; disposing a spacer element between the guide and the insertion tool to restrict relative movement therebetween; positioning an insertion assembly comprised of the bone anchor, the insertion tool, the repair filament, the connecting filament, the guide, and the spacer element adjacent to the surgical site such that the guide abuts the surgical site adjacent to the opening, the connecting filament being disposed in contact with the bone anchor and the guide; and removing the spacer element to advance the insertion assembly into the opening to secure the bone anchor within the opening. - View Dependent Claims (11, 12, 13, 14, 15)

16. A surgical system, comprising:
-
an anchor configured to be implanted in a surgical site, the anchor having a proximal end, a distal end, a body defined by a sidewall that extends from the proximal end to the distal end, and at least one axial bore extending through the body, the axial bore extending from the proximal end to the distal end, the anchor having a plurality of bone-engaging features on an outer surface thereof; an insertion tool having a proximal end, a distal end, and at least one lumen extending therethrough, the proximal end of the anchor being removably coupled to a terminal portion of the distal end of the insertion tool; a connecting filament located distal to the distal end of the anchor; and
a repair filament extending through at least a portion of the axial bore and the lumen, the repair filament being disposed around the connecting filament such that the repair filament is slidably coupled to the connecting filament; anda guide disposed around a portion of the insertion tool and the anchor, wherein the connecting filament is disposed between and in contact with at least one bone-engaging feature of the plurality of bone engaging-features and the quide. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
