US Patent:

8210085, Jul 3, 2012

Filed:

Aug 27, 2009

Appl. No.:

12/548984

Inventors:

Jason T. Perkins - Bethlehem PA, US
Krasimira Hristov - Belle Mead NJ, 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.

Dennis L. Furman - East Windsor NJ, US

International Classification:

A61B 17/06
A61B 17/04

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 17/04
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.

International Classification:

A61B 17/06
D04C 3/48

US Classification:

87 34

Abstract:

A system for making braided barbed sutures includes a filament winding assembly, a barbed insert including an elongated core and barbs extending outwardly from the elongated core, and a barbed insert dispenser opening defining a passageway for orienting the barbed insert as the barbed insert is dispensed into the filament winding assembly. The barbed insert dispenser opening allows longitudinal movement of the barbed insert relative to the barbed insert dispenser opening while simultaneously preventing twisting movement of the barbed insert relative to the barbed insert dispenser opening.
