Abstract:
A method for joining and holding closed a wound in bodily tissue, fastening junctions of wounds, tying off wounds, joining a foreign element to tissue, and altering the position of tissue using a barbed suture including sharp pointed ends. Each end of the suture includes barbs on that permit movement in an opposing direction to the barbs on the other end of the suture. This two-way barbed suture is used by the method of the present invention in applications including abdominal surgeries such as a Nissen fundoplication, laparoscopic uses such as stabilizing a bowel structure and performing a closure of a cystostomy, liver to bowel anastomosis, closure of an orifice of a Zenker's Diverticulum, endoscopic uses such as closure of ulcerative lesions or and post-procedural tissue defects, bladder wound closure, valve replacement surgery, device attachment, cosmetic surgery, and blood vessel wound closure.

Abstract:
A method of making a barbed suture by varying the blade geometry and/or the movement of the blade when cutting a suture is disclosed. The method can also be accomplished with a cutting device to create a plurality of barbs on the exterior of surgical suture. The barbs produced using the method with the cutting device can be the same or random configurations.

Abstract:
A method is provided for performing a procedure to reposition a portion of a breast using a suture including a plurality of barbs. The barbs on a first portion of the suture adjacent a first end of the suture permit movement of the suture through tissue in a direction of movement of the first end and prevent movement of the suture through tissue in a direction opposite the direction of movement of the first end. The barbs on a second portion of the suture adjacent a second end of the suture permit movement of the suture through tissue in a direction of movement of the second end and prevent movement of the suture through tissue in a direction opposite the direction of movement of the second end. The method comprises the steps of inserting the first end of the suture through a first insertion point and causing the first portion of the suture to engage a tissue, inserting the second end of the suture through the first insertion point and advancing the second end of the suture through breast tissue to a first exit point located on the breast caudally of the first insertion point, and manually grouping and advancing the breast tissue relative to the suture towards the first insertion point to reposition a portion of the breast tissue.

Abstract:
An apparatus for cutting barbs into a suture having a filament supply. The apparatus also has an in-feed collet for holding one end of a filament threaded therethrough. Further the apparatus has an out-feed collet for holding a second end of a filament threaded therethrough. Additionally, the apparatus has a holder positioned between said in-feed and out-feed collets for holding a filament suspended between the in-feed and out-feed collets. The apparatus also has a cutting assembly for cutting barbs in the filament tensioned between the in-feed and out-feed collets.

US Classification:
606228, 606232
Abstract:
A barbed suture for connecting tissue, and a combination surgical needle with a barbed suture. The suture includes an elongated body and a plurality of barbs projecting from the body. Each barb causes the suture to resist movement in an opposite direction from which the barb faces. The disposition of the barbs on the body may be staggered, twist cut multiple spiral, overlapping, or random. Also, the configuration of the barbs may be a certain spirality angle α, barb cut angle Θ, barb cut depth, barb cut length, barb cut distance, corrugated barb underside, arcuate barb base, or varying barb size.

Abstract:
A method is provided for joining and holding closed a wound in bodily tissue using a barbed suture including sharp pointed ends. The pointed end of the suture is inserted on a first side of the wound and pushed through the faces of the wound to an exit point on the second side of the wound that is longitudinally spaced in a first direction from the insertion point in the first side of the wound. The first end of the suture is pulled out of the tissue for drawing the first portion of the suture through the tissue while bringing the two sides of the wound together to a closed position along the first portion of the suture in the tissue. The second pointed end of the suture is inserted into the tissue at one side of the wound and pushed through the faces of the wound to an exit point on the other side of the wound longitudinally spaced in a second direction from the point of insertion of the second end of the suture at the one side of the wound. The second end is pulled out of the tissue for drawing the second portion of the suture through the tissue while bringing the sides of the wound together to the closed position along the second portion of the suture in the tissue.
