  • Patent number: 8210085
    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.

  • Patent number: 8101116
    Abstract: A device for making a seamless, anatomically contoured, prosthetic device for supporting or maintaining the position of mammalian tissue, organ or structure or a replacement thereof, such as a breast implant, includes a support plate, an ironing plate or a clamping plate and a core plate, each of which is made from a thermally conductive material. The support plate and the ironing or clamping plates have openings formed through the thickness thereof. The core plate has a core extending outwardly from a lower surface thereof which is received through the openings in the ironing or clamping plate and the support plate.

  • Publication number: 20110178608
    Abstract: An implantable prosthesis for repairing or reinforcing a tissue or muscle wall defect including a first composite structure including at least one layer of a non-absorbable material, wherein the first composite structure has a central portion sized and shaped to cover at least a portion of the tissue or muscle wall defect, and has an outer periphery. The prosthesis further includes a second structure having a reinforced central region and an outer peripheral edge, a reinforcing element positioned between the first and second structures, and having an outer periphery and a stiffness greater than that of the first and second structures, and at least one pulling element coupled to the reinforced central region of the second structure. The second structure is coupled to the first structure substantially only at their respective peripheries.

  • Publication number: 20110100377
    Abstract: A system for treating obstructive sleep apnea includes a first element implantable in a tongue and a second element implantable between muscle planes of an inframandibular region. The second element has a first end coupled with the first element and a second end coupled with a hyoid bone for preventing the base of the tongue from collapsing against an opposing pharyngeal wall during sleep. The first and second implantable elements have outer surfaces that are substantially impermeable to tissue in-growth to allow for post-surgical adjustment or removal, if necessary. The first implantable element is elongated and includes a first end, a second end, and a center section located between the first and second ends. The center section is implantable in the tongue, and the first and second ends of the first implantable element are advanceable beneath the tongue for being coupled with the anterior end of the second implantable element.

  • Publication number: 20110054522
    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.

  • Publication number: 20100160961
    Abstract: A surgical suture includes a shaft having a leading end, a trailing end, and an outer surface extending between the leading and trailing ends. The surgical suture includes a plurality of flexible protrusions extending from the shaft, and a lumen extending between the leading and trailing ends of the shaft. The shaft includes a plurality of openings formed in the outer surface thereof that are in communication with the lumen. The shaft includes a first axial opening at the leading end thereof in communication with the lumen and a second axial opening at the trailing end thereof in communication with the lumen. A flowable material may be disposed in the lumen. After the surgical suture is implanted, the flowable material is adapted to pass from the lumen and through the plurality of openings in the outer surface of the shaft for contacting tissue surrounding the suture.

  • Publication number: 20080312688
    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.
