  • Publication number: 20170189165
    Abstract: A mammary implant and method of making are provided herein. The implant includes an outer shell configured to retain fluid therein, an injection element coupled to the outer shell and adapted to receive therethrough an injection device for injecting fluid into the outer shell, and an injection marker zone made of a material having ultrasonically detectable markers incorporated therein. The markers are a plurality of microcavities that are located relative to the injection element so that, when ultrasonically detected, such detection indicates a location of the injection element.

  • Publication number: 20160279398
    Abstract: A dilation assembly includes a shaft and a dilator coupled with the distal end of the shaft. The dilator includes a proximal end, a distal end, and a center portion positioned between the proximal end and the distal end. The center portion dilates from a first configuration to a second configuration. The center portion has a larger diameter than the proximal end and the distal end when the center portion is in the second configuration. At least one gripping feature is positioned on at least a portion of the exterior surface of the center portion. The gripping feature provides friction between the center portion and a bodily lumen when the center portion is in the second configuration.

  • 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.
