  • Patent number: 8777989
    Abstract: Subcutaneous sinusoidal wound-closure techniques use one-way sutures. The one-way sutures have tissue-grasping surface features which allow passage of the suture in one direction through tissue, but not in the opposite direction. In closing a wound, the one-way suture is deployed along a curvilinear path which passes alternately through subcutaneous tissue on opposed sides of the wound. The wound-closure techniques allow approximation of the sides of the wound without knots, avoid loop stitching and reduce scarring.

  • Patent number: 8777988
    Abstract: Endoscopic methods utilize self-retaining sutures to approximate tissue in a cavity of a subject. An endoscopic instrument is provided containing the self-retaining suture. The endoscopic instrument may be provided in combination with an endoscope and/or an endoscopic manipulator. The endoscopic instrument is passed through a cavity wall into a cavity of a patient. The self-retaining suture is deployed, using the endoscopic instrument, into a first tissue portion and a second tissue portion within the cavity. The self-retaining suture may be deployed endoscopically in patterns which include, purse string stitch, alpha stitch, linear stitching, curvilinear stitching, continuous helical stitch, and continuous sinusoidal stitch.

  • Patent number: 8764776
    Abstract: An anastomosis procedure utilizes a self-retaining suture to secure one vessel to another vessel. One or more self-retaining sutures are deployed around the interface between the vessels. The self-retaining sutures have tissue-grasping surface features which allow passage of the sutures in one direction through tissue, but not in the opposite direction. The self-retaining sutures may be deployed using a needle attached to the end of the sutures. The anastomosis technique may be performed without using knots.

  • Publication number: 20100318123
    Abstract: An anastomosis procedure utilizes a self-retaining suture to secure one vessel to another vessel. A single self-retaining suture is deployed in a continuous pattern around the interface between the vessels. The self-retaining suture has tissue-grasping surface features which allow passage of the suture in one direction through tissue, but not in the opposite direction. The self-retaining suture may be deployed using a needle attached to the end of the suture. The continuous anastomosis technique may be performed without using knots.

  • Publication number: 20100087855
    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.

  • Publication number: 20080234731
    Abstract: A suture anchor is provided for approximating tissue to bone or other tissue. The suture anchor comprises an anchor member to fixedly engage the bone for securing the anchor member relative to the bone. A plurality of sutures are mounted to the proximal end of the anchor member so that the sutures extend outwardly from the anchor member. Each suture has a sharp pointed distal end for penetrating the tissue and a plurality of barbs extending from the periphery and disposed along the length of the body of the suture. The barbs permit movement of the sutures through the tissue in a direction of movement of the pointed end and prevent movement of the sutures relative to the tissue in a direction opposite the direction of movement of the pointed end. At least one pointed distal end of at least one suture comprises a needle.
