Assembly for Securing Gastrointestinal Tissue Folds

摘要

Assembly for endoscopically securing gastrointestinal tissue folds, comprising a first tissue anchor and a second tissue anchor, a first suture thread part and a second suture thread part, each of the first and second thread parts having a connected end and a free end opposite the connected end. The first thread part and the second thread part are tied to each other through a sliding knot, such that the first thread part firms a post of the sliding knot along which the sliding knot is arranged to slide during tightening of the assembly and such that the second thread part wraps around the post to create the sliding knot. The first thread part extends from the first anchor to past the sliding knot where the first thread part's free end forms a post free end, and the second thread part extends from the second anchor to past the sliding knot where the second thread part's free end is free, such that the sliding knot is interposed between the first and second anchors. The first or the second anchor comprises a knot retaining through hole, wherein the post free end slidingly passes through the knot retaining through hole, the knot retaining through hole having a size preventing the sliding knot to pass through the knot retaining through hole, such that the anchor can be used as a knot retainer during tightening.

1. An assembly for endoscopically securing gastrointestinal tissue folds, comprising:
a first tissue anchor; a second tissue anchor; a first suture thread part and a second suture thread part, each of the first suture thread part and the second suture thread part having a secured end and a free end opposite the secured end; wherein the first suture thread part and the second suture thread part are connected to each other via a sliding knot, such that the first suture thread part forms a post of the sliding knot along which the sliding knot is arranged to slide during tightening of the assembly and such that the second suture thread part wraps around the post to create the sliding knot; wherein the assembly is configured to be tightened by sliding the sliding knot along the post; wherein the first suture thread part extends from the first tissue anchor past the sliding knot where the free end of the first suture thread part forms a post free end, and the second suture thread part extends from the second tissue anchor past the sliding knot where the free end of the second suture thread part is free, such that the sliding knot is interposed between the first tissue anchor and the second tissue anchor, the second tissue anchor further comprising a first through hole; and the post free end being configured to slide through the first through hole, the first through hole having a size preventing the sliding knot from passing through the first through hole, such that the second tissue anchor is configured to act as a knot retainer during tightening.
