  • Publication number: 20070065663
    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.

  • Publication number: 20060135994
    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 ?, barb cut angle ?, barb cut depth, barb cut length, barb cut distance, corrugated barb underside, arcuate barb base, or varying barb size.

  • Patent number: 7056331
    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.

  • Publication number: 20050267531
    Abstract: A barbed suture including a body with barbs on the periphery, a pointed end, and an anchor at one end to resist movement of the suture in the direction of the pointed end is provided. One or more limbs on the anchor may be provided, which may be arcuate, of varying lengths, and of varying distribution about the periphery of the suture body. Other anchor designs are provided. Methods of placing single-directional and bi-directional barbed sutures to approximate the tissue on each side of a wound and to position and support tissue in the absence of a wound, as in cosmetic surgery, are provided, and may include terminal J-stitches or S-stitches. Methods of placement may be made with sharp, pointed ends, which may be needles, or insertion devices. Sinusoidal patterns of sutures that have amplitudes generally perpendicular to the resultant holding force of the suture are provided.

  • Patent number: 6599310
    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.
