摘要:
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.
摘要:
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.

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.
摘要:
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.
