Methods for using looped tissue-grasping devices
A method for repairing friable tissue having a defect therein includes providing a looped barbed suture having a plurality of barbs extending outwardly therefrom along at least a portion of a length thereof, and having first and second ends, first and second end portions and a middle portion therebetween. The first and second ends are fixedly coupled to a single needle, and the plurality of barbs extends outwardly away from the needle. The steps further include placing the looped barbed suture around an outer surface of the friable tissue in a spaced apart configuration and so as to extend across the defect, passing the needle through the friable tissue and around the middle portion of the looped barbed suture one or more times at the middle portion, and removing the needle from the looped barbed suture.
1. A method for repairing a friable organ having a defect therein, comprising the steps of:
providing a looped barbed suture having a plurality of barbs extending outwardly therefrom along at least a portion of a length thereof, and having first and second ends, first and second end portions and a middle portion therebetween, wherein the first and second ends are fixedly coupled to a single needle, and wherein the plurality of barbs extend outwardly away from the needle;
placing the looped barbed suture around and on an outer surface of the friable organ in a spaced apart configuration without penetrating said friable organ with the needle and so as to extend across the defect, wherein the middle portion of the suture is positioned substantially transversely on whole to the first and second portions of the looped barbed suture and positioned substantially parallel to said defect;
following the placing step, passing the needle through the friable organ in the vicinity of and around the middle portion of the looped barbed suture one or more times at the middle portion; and
removing the needle from the looped barbed suture.
2. The method according to claim 1 , wherein the needle is passed around the middle portion of the looped barbed suture a plurality of times at successive intervals along a length of the middle portion.
3. The method according to claim 2 , wherein the suture is comprised of a material selected from the group consisting of polydioxanone, polyglactin, polyglycolic acid, copolymers of glycolide and lactide, polyoxaesters, poly caprolactone, polypropylene, polyethylene, polyvinylidene fluoride (PVDF), ultra high molecular weight polyethylene (UHMWPE), polyesters, polyethylene terephthalate, glycol-modified polyethylene terephthalate, polytetrafluoroethylene, fluoropolymers, nylons, and combinations thereof.
4. The method according to claim 2 , wherein the looped barbed suture further comprises a widened portion along at least a portion of a length thereof.
5. The method according to claim 4 , wherein the widened portion is along at least a portion of a length of the middle portion.
6. The method according to claim 4 , wherein the widened portion is along at least a portion of the first and/or second end portions.
7. The method according to claim 4 , wherein the widened portion is integral with the looped barbed suture.
8. The method according to claim 4 , wherein the widened portion is a second element coupled to the looped barbed suture.
9. The method according to claim 1 , wherein the friable organ is a liver.
