Surgical Filament Snare Assemblies

摘要

A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably connected, to the filament engagement feature of the anchor. The first and second noose limbs emerge from the anchor as first and second free filament limbs which are capable of being passed through tissue to be repaired and then passable through the noose. The noose, such as one or more half-hitches, is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after the anchor is fixated. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs at least through the tissue as a single unit.

主权项

1. A surgical repair method, comprising:
selecting a surgical filament assembly comprising:
a slidable knot having on one side thereof a cinch noose loop defined by a first filament and a second filament, the slidable knot having on the other side thereof first and second filament limbs; anda flexible sleeve removably encapsulating at least a portion of the first and second filament limbs; fixing an anchor in bone in proximity to detached soft tissue; passing a first end of each of the first and second filament limbs through a portion of the detached soft tissue and around an engagement feature of the anchor such that the cinch noose loop extends from one side of the anchor and the sleeve extends from another side of the anchor; passing the first end of each of the first and second filament limbs through the cinch noose loop; collapsing the cinch noose loop around the first and second filament limbs disposed therethrough to engage the soft tissue; and advancing the collapsed cinch noose loop distally to bring the tissue into proximity with the bone.
