  • Patent number: 8100940
    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: 8083770
    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.

  • 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: 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: 20100298869
    Abstract: A tissue connector has a first pointed end, an anchor end, a body with a periphery and a plurality of barbs projecting from said periphery of said body. The plurality of barbs are yieldable in one direction, which direction is the direction of motion of the first pointed end through tissue, and are rigid in an opposite direction, which is in the direction of the anchor end. At axial locations of said body, said barbs are about equally located about the periphery of said body. At axial locations on a cylindrical periphery of the body barbs are locate at about 120 degree spacings. The barbs are conically shaped.

  • Publication number: 20100298867
    Abstract: A tissue connector has a first end, a second end, a body with a periphery and a plurality of tissue grasping protrusions extending from said periphery of said body. The plurality of protrusions are adapted to grasp tissue in one direction of movement of the connector through tissue and are not adapted to grasp tissue in an opposite direction of movement of the connector through tissue. At axial locations of said body, three of said protrusions are about equally located about the periphery of said body. At axial locations on a cylindrical periphery of the body, protrusions are located at about 120 degree spacings.

  • 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.

  • Patent number: 7806908
    Abstract: A barbed bodily tissue connector for insertion into tissue comprises an elongated body having a substantially polygonal periphery in cross-section including at least three sides. Each side meets an adjacent side at an edge of the elongated body. A plurality of barbs project from the edges of the body. The barbs are configured such that they are yieldable in a direction toward the body and resist retraction from tissue in an opposite direction.

  • Patent number: 7226468
    Abstract: A barbed tissue connector is disclosed for use in closing a body wound. The connector includes an elongated body and a pointed end to facilitate insertion of the connector into tissue. A plurality of closely-spaced barbs are disposed on the body from the pointed end of the connector to a predetermined location on the body. The barbs are yieldable toward the body to make it easier to insert the connector in tissue, and the barbs are generally rigid in an opposite direction to hold the connector in the tissue. The body of the connector is substantially rigid and is sufficiently resilient to return to a predetermined position after deflection therefrom. The connector can be manually inserted into the tissue of a patient, or the connector can be inserted by means of an inserting device which is retracted after the connector is in place.

  • 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.
