Filed:

Aug 27, 2009

Appl. No.:

12/549046

Inventors:

Jesse G. Nawrocki - Annandale NJ, US
Dennis L. Furman - East Windsor NJ, US
Krasimira Hristov - Belle Mead NJ, US
Jason T. Perkins - Bethlehem PA, US

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61B 17/04

US Classification:

606228

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.

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 suture device with a composite end effector, the composite end effector including a suture with an unmodified fixation element at a distal end and an overlying attachment piece disposed over the proximal end of the unmodified fixation element. The resulting composite end effector has improved strength and avoids the need for affixation methods such as welding or chemical affixation.
