  • Publication number: 20130165971
    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: 20120101522
    Abstract: A method and device for anchoring a length of self-retaining suture. The method of anchoring includes providing for an assembly having a length of self-retaining suture and a suture insertion device. The length of suture includes at least a portion of the length having a plurality of retainers thereon extending in a first direction. The insertion device has a length and a recess to receive a portion of the suture length. The method further includes placing a portion of the suture length in the recess and inserting the device into the body of a mammal until the recess reaches a predetermined location thereby forming an insertion pathway. The method further includes retrieving the insertion device from the body by moving the insertion device in a direction substantially opposed to the insertion pathway.

  • Patent number: 8032996
    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.

  • Patent number: 7913365
    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.

  • Patent number: 7857829
    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.

  • Publication number: 20100318124
    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.

  • 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: 20100305401
    Abstract: Endoscopic systems 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.

  • Publication number: 20100298874
    Abstract: A barbed suture with a first end and a second end and a body with a plurality of barbs extending from the body. Each barb causes the suture to resist movement in an opposite direction from which the barb faces. Projections extend from said suture. The projections can also engage tissue. The barbs cover the projections when the first end of the suture is moved in tissue and exposes the projections in order to engage tissue when the suture is moved in the direction of the second end through tissue.

  • Publication number: 20100298871
    Abstract: A self-retaining suture includes a plurality of tissue retainers which allow deployment in a deployment direction, but prevent movement in the opposite direction. The self-retaining suture has a needle at the proximal end and a tissue anchor at the distal end. The tissue anchor includes a curved portion of the suture formed into a loop which anchors the suture in the tissue. Additionally, the suture can be passed through a tissue and then passed through the loop to secure the distal end of the suture to the tissue.
