  • Patent number: 9206535
    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.

  • Patent number: 9011487
    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 through the pledget, 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.

  • Patent number: 8888796
    Abstract: A device for tensioning barbed sutures used for securing tissue or prosthetic devices includes a handle, and a shaft having a proximal end connected with the handle and a distal end remote therefrom. The distal end of the shaft includes a pressure applying surface for pressing against the tissue and the prosthetic devices. The tensioning device includes a pair of grooves extending through the shaft from the pressure applying surface at the distal end of the shaft toward the proximal end of the shaft. A barbed suture is tensioned by aligning a first section of the suture in the first groove and a second section of the suture in the second groove. After the first and second suture sections are aligned in the grooves, the proximal ends of the sections may be pulled for applying tension to the suture.

  • Patent number: 8747436
    Abstract: 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.

  • Patent number: 8733223
    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.

  • Publication number: 20140081321
    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.

  • Patent number: 8663277
    Abstract: A suture assembly and a method for making the same is provided. The suture assembly includes a plurality of unbarbed filamentary elements intertwined with one another and at least one barbed filamentary element having a longitudinal axis and having plurality of barbs extending outwardly therefrom in a first direction less than 90 degrees from the longitudinal axis. According to exemplary embodiments, the at least one barbed filamentary may be intertwined along its length with the plurality of unbarbed filamentary elements, and the plurality of barbs extending outwardly beyond the unbarbed filamentary elements, or the primary outer periphery of the at least one barbed filamentary element may be contained within the intertwined unbarbed filamentary elements with the plurality of barbs extending through and outwardly from the plurality of unbarbed filamentary elements.
