Publication number: 20170014128Abstract: The present invention discloses methods for producing a surgical suture having a reduced cross-sectional area portion from monofilaments fibers of various polymeric and metallic materials. Also disclosed are novel sutures having novel tips. Novel suture tipping apparatuses are also disclosed. The monofilament is subjected to the application of thermal treatment coupled with application of mechanical shaping of the fiber element to produce a deformed cross sectional portion of the suture body. The deformed suture body region is subsequently subjected to a trimming operation within a punching/stamping die. The reduced section of the suture body region and is severed to form a suture having a reduced-cross sectional area end portion. Preferably, each reduced region is severed approximately in the center of the trimmed reduced cross sectional area portion to form a suture having both ends of a reduced cross-sectional area.Type: ApplicationFiled: September 28, 2016Publication date: January 19, 2017Inventors: Robert Anthony Rousseau, David C. Lindh, SR.

Patent number: 8747436Abstract: Surgical sutures having a core extending along a length thereof between a first end and a second end, and a plurality of sets of first and second projections, wherein the first projections extend in a direction of a first end of the suture and the second projections extend in a direction of a second end of the suture. The first projections may be sized and shaped, and positioned relative to the second projections so as to be capable of substantially shielding the second projections when the surgical suture is drawn through tissue by the second end thereof. The first projections may additionally or alternatively be capable of overlapping and substantially covering a distal end of the respective second projections when the suture is drawn through tissue by the second end.Type: GrantFiled: June 13, 2007Date of Patent: June 10, 2014Assignee: Ethicon, Inc.Inventors: Jesse G.

Patent number: 8733223Abstract: 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.Type: GrantFiled: May 4, 2012Date of Patent: May 27, 2014Assignee: Ethicon, Inc.Inventors: David C. Lindh, Sr., Jason T.

Patent number: 8561617Abstract: A method of treating obstructive sleep apnea includes providing an elongated element having a central buttress area and first and second arms extending from opposite ends of the central buttress area. The method includes implanting the central buttress area in a tongue so that a longitudinal axis of the central buttress area intersects an anterior-posterior axis of the tongue. The first and second arms are advanced through the tongue until the first and second arms engage inframandibular musculature. Tension is applied to the first and second arms for pulling the central buttress area toward the inframandibular musculature for moving a posterior surface of the tongue away from an opposing surface of a pharyngeal wall. The first and second arms are anchored to the inframandibular musculature for maintaining a space between the posterior surface of the tongue and the opposing surface of the pharyngeal wall.Type: GrantFiled: October 30, 2008Date of Patent: October 22, 2013Assignee: Ethicon, Inc.Inventors: David C.
