  • Patent number: 10973513
    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.

  • Publication number: 20200390441
    Abstract: A device is disclosed for the securement of dermal tissues. The device provides approximation and eversion of the tissue as well as the placement of a fixation element that bridges a wound. The fixation element may be produced in several fixed or dynamic configurations that may or may not alter the ability to engage tissue in response to stresses placed upon the fixation member post-deployment. The delivery device inserts the fastener percutaneously through the epidermis into the sub-dermal position without entering the wound margins with any part of the approximation portion of the delivery device.

  • Patent number: 10478178
    Abstract: 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.

  • Patent number: 10188379
    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.

  • Patent number: 9877862
    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.

  • Patent number: 9636207
    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.

  • 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.
