| 20080221617 | BARBED TISSUE CONNECTOR - 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. | 09-11-2008 |
| 20090018577 | BARBED SUTURES - 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. | 01-15-2009 |
| 20100298637 | SUTURE WITH A POINTED END AND AN ANCHOR END AND WITH EQUALLY SPACED TISSUE GRASPING PROTRUSIONS LOCATED AT SUCCESSIVE AXIAL LOCATIONS - A tissue connector has a first pointed end, an anchor end, a body with a periphery and a plurality of protrusions projecting from said periphery of said body. The plurality of protrusions are adapted to grasp tissue in a direction of movement of the first end of the connector through tissue and are not adapted to grasp tissue in an opposite direction of movement of the connector through tissue, which is in the direction of the anchor end. At axial locations of said body, three said protrusions are about equally located about the periphery of said body. At axial locations on a cylindrical periphery of the body protrusions are locate at about 120 degree spacings. | 11-25-2010 |
| 20100298867 | TISSUE CONNECTOR WITH TISSUE GRASPING PROTRUSIONS EQUALLY SPACED ABOUT THE PERIPHERY OF THE CONNECTOR AT SUCCESSIVE AXIAL LOCATIONS - 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. | 11-25-2010 |
| 20100298868 | TISSUE CONNECTOR WITH YIELDABLE BARBS EQUALLY SPACED ABOUT THE PERIPHERY OF THE CONNECTOR AT SUCCESSIVE AXIAL LOCATIONS - A tissue connector has a first end, a second end, a body with a periphery and a plurality of barbs extending from said periphery of said body. The plurality of barbs are yieldable in one direction and are rigid in an opposite direction. At axial locations of said body, three of said barbs are about equally located about the periphery of said body. At axial locations on a cylindrical periphery of the body, barbs are located at about 120 degree spacings. | 11-25-2010 |
| 20100298869 | SUTURE WITH A POINTED END AND AN ANCHOR END AND WITH EQUALLY SPACED YIELDABLE TISSUE GRASPING BARBS LOCATED AT SUCCESSIVE AXIAL LOCATIONS - 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. | 11-25-2010 |
| 20100298871 | SELF-RETAINING WOUND CLOSURE DEVICE INCLUDING AN ANCHORING LOOP - 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. | 11-25-2010 |
