Appl. No.:

12/548984

Inventors:

Jason T. Perkins - Bethlehem PA, US

Jesse G. Nawrocki - Annandale NJ, US
Robert J. Tannhauser - Bridgewater NJ, US

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

D04C 3/40

US Classification:

87 34

Abstract:

A system for making braided barbed sutures includes a filament winding assembly, and a guide assembly including at least one barbed insert dispenser opening defining a passageway for orienting a barbed insert. The guide assembly is adapted to dispense at least one barbed insert from the dispenser opening into the filament winding assembly for winding a plurality of filaments around the at least one barbed insert for making a braided barbed suture. The passageway of the dispenser opening is adapted to allow longitudinal movement of the barbed insert relative to the passageway while simultaneously preventing twisting movement of the barbed insert relative to the passageway. As the barbed insert is being dispensed, the barbed insert dispenser opening is selectively rotatable for imparting rotation to the barbed insert as the filaments are wound about the barbed insert. The passageway may be an elongated slit having a greater width than height.

Abstract:

A surgical suture includes an elongated core having a first leg and a second leg, a first set of barbs projecting from the first leg of the core, and a second set of barbs projecting from the second leg of the core. The suture has a stop projecting from the core that is located between the first and second sets of barbs, and a braid surrounding the elongated core and the stop for strengthening the suture. The suture includes a pledget having first and second openings extending therethrough, with the first leg extending through the first pledget opening, the second leg extending through the second pledget opening, and the stop extending between the first and second pledget openings.

International Classification:

A61B 17/04

US Classification:

606228

Abstract:

A wound closure device having a filamentary element having a proximal end and a distal end, and a stop element coupled thereto and having a leading edge area defined by thickness and a width and having a total surface area. The leading edge area is substantially perpendicular to a longitudinal axis of the filamentary element. The device may have a ratio of the leading edge area to the total surface area that is less than 10%, a ratio of the length to the maximum thickness of the stop element that is at least 4, or a ratio of the length to the width of the stop element is at least 1 for any given thickness.

Inventors:

Jesse G. Nawrocki - Annandale NJ, US

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61B 17/06

US Classification:

606228

Abstract:

A wound closure device includes a filamentary element having a proximal end and a distal end, and a plurality of barbs extending outwardly from the filamentary element. Each barb has a base connected with the filamentary element, a tip spaced from the base, and an outer edge that extends between the base and the tip. The outer edge includes a first section having a concave surface that extends between the base and a transition point of the barb and a second section having a convex surface that extends between the transition point of the barb and the tip of the barb. The outer edge transforms from the concave surface of the first section to the convex curve of the second section at the transition point of the barb. The tip of the barb has a convexly curved surface facing the distal end of the filamentary element. The unique dual radius shape of the outer edge of the barbs and the tips of the barbs minimizes resistance when the filamentary element is pulled in a first direction through tissue and maximizes resistance to movement when the filamentary element is pulled in an opposite, second direction through tissue for holding the wound closure device stationary.

International Classification:

A61B 17/04
A61B 17/06

Abstract:

A device for guiding a barbed suture into a braider preferably includes an elongated body having a proximal end, a distal end, and a longitudinal axis that extends from the proximal end to the distal end of the elongated body. The elongated body includes a first channel extending along the longitudinal axis of the elongated body and having a first distal opening at the distal end of the elongated body, whereby the said first channel has a first cross-sectional area, and a second channel extending along the longitudinal axis of the elongated body and having a second distal opening at the distal end of the elongated body, whereby the second channel has a second cross-sectional area that is different than the first cross-sectional area of the first channel. The device has an elongated slot extending along the longitudinal axis of the elongated body that interconnects the first and second channels. A barbed suture is loaded into the elongated body. The barbed suture includes an elongated core having a proximal end, a distal end, a barbed section including barbs extending outwardly from the elongated core, an end effector secured to the proximal end of the elongated core, and an interconnecting segment of the elongated core that is distal to the end effector and proximal to the barbed section. The barbed section of the barbed suture is disposed within the first channel, the end effector of the barbed suture is disposed within the second channel, and the interconnecting segment of said barbed suture extends through the elongated slot.

International Classification:

A61B 17/06
A61L 17/10

Abstract:

A braided barbed suture includes a barbed monofilament insert including an elongated core having a thickness and a plurality of barbs projecting outwardly from opposite sides of the elongated core. The braided barbed suture includes a braided sheath surrounding the elongated core to form a composite core of the braided barbed suture. The composite core has a thickness and the elongated core is located in a center of the composite core. The elongated core thickness is about 6-8 mil and the composite core thickness is about 13-18 mil. A ratio of the elongated core thickness relative to the composite core thickness is between about 0.16 to 0.91. The elongated core has transition zones that form a concave profile. The braided barbed suture has a single breaking point for both the braided sheath and the barbed monofilament insert. The barbed monofilament insert has a PDS monofilament core, and the braided sheath is a VICRYL multifilament yarn braided sheath.
