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 α, barb cut angle θ, barb cut depth, barb cut length, barb cut distance, corrugated barb underside, arcuate barb base, or varying barb size.
Claims19
A barbed suture for connecting human or animal tissue in combination with a surgical needle, said combination comprising a barbed suture attached to a surgical needle, wherein the suture comprises a plurality of barbs projecting from an elongated body having a first end and a second end and a diameter, each barb facing in a direction and being adapted for resisting movement of the suture, when in tissue, in an opposite direction from the direction in which the barb faces, and wherein the surgical needle has a diameter at the needle's thickest part with a ratio of the surgical needle diameter to the barbed suture diameter of from about 3:1 to about 1.1:1.
A barbed suture for connecting human or animal tissue in combination with a surgical needle, said combination comprising a barbed suture attached to a surgical needle, wherein the suture comprises a plurality of barbs projecting from an elongated body having a first end, a second end, and a diameter, each barb facing in a direction and being adapted for resisting movement of the suture, when in tissue, in an opposite direction from the direction in which the barb faces, wherein the barbed suture and the surgical needle have an attachment selected from the group consisting of swaging, channel wrapping, heat shrinking, and eyelet threading, and wherein the surgical needle has a diameter at the needle's thickest part with a ratio of the surgical needle diameter to the barbed suture diameter of from about 2:1 to about 1.1:1.
A barbed suture for connecting human or animal tissue in combination with a surgical needle, said combination comprising a barbed suture attached to a surgical needle, wherein the suture comprises a plurality of barbs projecting from an elongated body having a first end, a second end, and a diameter, each barb facing in a direction and being adapted for resisting movement of the suture, when in tissue, in an opposite direction from the direction in which the barb faces, wherein the barbs are in a staggered disposition, and wherein the surgical needle has a diameter at the needle's thickest part with a ratio of the surgical needle diameter to the barbed suture diameter of from about 3:1 to about 1.1:1.
A barbed suture for connecting human or animal tissue in combination with a surgical needle, said combination comprising a barbed suture attached to a surgical needle, wherein the suture comprises a plurality of barbs projecting from an elongated body having a first end, a second end, and a diameter, each barb facing a direction and being adapted for resisting movement of the suture, when in tissue, in an opposite direction from the directing in which the barb faces, wherein the barbs are in a staggered disposition, and wherein the surgical needle has a diameter with a ratio of the surgical needle diameter to the barbed suture diameter of about 3:1 to about 1.1:1.
A barbed suture for connecting human or animal tissue in combination with a surgical needle, said combination comprising a barbed suture attached to a surgical needle, wherein the suture comprises a plurality of barbs projecting from an elongated body having a first end, a second end, and a diameter, each barb facing in a direction and being adapted for resisting movement of the suture, when in tissue, in an opposite direction from the direction in which the barb faces, wherein the barbs are in a random disposition, and wherein the surgical needle has a diameter at the needle's thickest part with a ratio of the surgical needle diameter to the barbed suture diameter of about 3:1 to about 1.1:1.
