Abstract
An all-suture anchor for attaching soft tissue to bone while creating an interference fit within a bone hole, and a deployment device for the all-suture anchor. The all-suture anchor includes an anchor body having first and second ends. The second end is folded toward the first end, creating a looped distal end of the anchor body, while the first and second ends of the anchor body form a proximal end. The anchor body is composed of a first material having a first density. A passing filament, of a second (different) density, is woven through the anchor body at passing locations such that a pair of free ends of the passing filament extends from the proximal end of the anchor body. The all-suture anchor additionally includes a binding filament bound axially at the proximal end of the anchor body around the first end and the second end of the anchor body.
Core Innovation
The invention relates to an all-suture anchor having an anchor body with a first end and a second end, where the second end is folded toward the first end to create a looped distal end. The first end and second end of the anchor body form a proximal end of the anchor body. A passing filament is provided with a pair of free ends that extend from the proximal end, and the passing filament is woven through the anchor body at a plurality of passing locations.
The anchor body is composed of a first material having a first density, and the passing filament is composed of a second material having a second density different from the first density. A binding material is bound axially at the proximal end of the anchor body around the first end and the second end and also around the pair of free ends of the passing filament. This construction uses different material density between the anchor body and the passing filament while mechanically securing the woven passing filament at the proximal end.
An additional deployment concept is described using a deployment assembly with an inserter/driver and a polymer tube/channel whose diameter increases in the deployed state, locking anchor expansion into the expanded tube without requiring a minimum travel distance. Further embodiments describe piercing configurations and woven anchor architectures that create contrasting density zones and different woven/pleated/fibrous constructs, including configurations intended to reduce abrasion or rolling behavior, and hybrid expandable portions that wedge and lock in a bone hole.
Claims Coverage
The independent claim defines an all-suture anchor with looped distal end geometry, a woven passing filament at multiple locations, different-density materials for the anchor body and passing filament, and an axially bound binding material securing the proximal ends and the free ends of the passing filament. Dependent claims further specify particular anchor-body and binding material structures and a deployable-state thickness relationship.
Looped distal end formed by folding the anchor body
The anchor body has a first end and a second end, the second end folded toward the first end, creating a looped distal end; the first end and second end form a proximal end of the anchor body.
Passing filament woven through the anchor body at multiple passing locations
A passing filament having a pair of free ends is woven through the anchor body at a plurality of passing locations such that the pair of free ends extend from the proximal end of the anchor body.
Different-density anchor body and passing filament
The anchor body is composed of a first material having a first density, and the passing filament is composed of a second material having a second density different than the first density.
Axially bound proximal binding material around anchor ends and passing free ends
A binding material is bound axially at the proximal end of the anchor body around the first end and the second end of the anchor body and around the pair of free ends of the passing filament.
Overall, the claim coverage centers on an all-suture anchor that combines a looped distal anchor geometry with a woven passing filament at multiple locations, enforces different material densities between the anchor body and the passing filament, and secures the proximal ends using axially bound binding material around both the anchor-body ends and the passing filament free ends.
