Systems, devices, and methods for securing tissue using hard anchors
First Claim
1. A surgical soft tissue repair device, comprising:
- an anchor configured to be fixated in a bone and having at least one bore extending from a proximal terminal end of the anchor to a distal terminal end of the anchor, the anchor having a plurality of bone-engaging surface features disposed on an outer surface thereof, each bone-engaging surface feature of the plurality of bone-engaging surface features having a tapered surface that is tapered inwards towards a central longitudinal axis of the anchor from an outer, proximal terminal end of the tapered surface to an inner, distal terminal end of the tapered surface as the tapered surface extends from the proximal terminal end of the anchor towards the distal terminal and of the anchor, the tapered surface being longer than a second surface of each bone-engaging surface feature, the second surface extending from the outer, proximal terminal end of the tapered surface, towards the central longitudinal axis, and terminating prior to an inner, distal terminal end of a tapered surface of an adjacent bone-engaging surface feature of the plurality of bone-engaging surface features;
a repair filament; and
a connecting filament in sliding engagement with the repair filament at the distal terminal end of the anchor, the connecting filament effective to connect the repair filament to the anchor,wherein the connecting filament is disposed at the distal terminal end of the anchor in both a pre-installation configuration of the anchor in a bone, when the anchor has not been fixated in a bone, and a post-installation configuration of the anchor in a bone, when the anchor has been fixated in a bone.

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.

11. A surgical repair method, comprising:
-
inserting an anchor having a plurality of bone-engaging surface features disposed on an outer surface thereof distally, into a hole in a bone at a location proximate to a detached soft tissue such that a first portion of a bone-engaging surface feature of the plurality of bone-engaging surface features that engages the bone is tapered inwards towards a central longitudinal axis of the anchor from an outer, proximal terminal end of the first portion to an inner, distal terminal end of first portion, the first portion being longer than a second portion of the bone-engaging surface feature, the second surface extending from the outer, proximal terminal end of the first portion, towards the central longitudinal axis, and terminating prior to an inner, distal terminal end of a first portion of an adjacent bone-engaging surface feature of the plurality of bone-engaging surface features, the anchor having a bore extending therethrough and the anchor being coupled to a snare assembly by a connecting filament that is disposed in or adjacent to the bore at a position distal to the snare assembly, the snare assembly having a collapsible snare at one end thereof and at least one elongate filament extending therefrom, the at least one elongate filament having a terminal end opposite the collapsible snare, and the connecting filament being slidably coupled to the at least one elongate filament at a distal terminal end of the anchor; passing at least one of the collapsible snare and the terminal end of the at least one elongate filament through at least a portion of the detached soft tissue; inserting the terminal end of the at least one elongate filament through the collapsible snare; collapsing the collapsible snare around the at least one elongate filament; and sliding the collapsed snare toward the detached soft tissue to apply tension to the at least one elongate filament between the anchor and the detached soft tissue so as to bring the detached soft tissue into proximity with the bone, wherein a location of the connecting filament with respect to the anchor during the anchor insertion step is substantially the same as a location of the connecting filament with respect to the anchor during the sliding the collapsed snare step. - View Dependent Claims (12, 13, 14)
