  • 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.

  • Publication number: 20150327985
    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: 20150272722
    Abstract: An expandable mammary implant including a shell having an anterior face and a posterior face. The anterior has an upper pole portion and a lower pole portion meeting at an apex, and an injection zone for receiving fluid therethrough to inflate the implant. A reinforcement material is coupled to the shell in a reinforcement zone. The reinforcement material is coupled to the shell so as to at least coincide with the upper pole portion and a peripheral rim portion that extends from the posterior face upwardly into said anterior face by a predetermined distance.

  • Publication number: 20150272723
    Abstract: An expandable mammary tissue implant including a shell having an anterior face and a posterior face, the anterior face having an upper pole portion and a lower pole portion meeting at an apex, and an injection zone for receiving fluid therethrough to inflate the implant. The implant further includes a vertical tether member having first and second ends and a central region therebetween having an aperture therethrough. The central region is coupled to the anterior face of the implant at a location such that the injection zone is positioned within the aperture in the central region. The first and second ends of the vertical tether member are coupled to the posterior face of the implant.

  • 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: 20080281338
    Abstract: A surgical suture system (1, 21, 41) is illustrated and described. The object, namely to permit simple correction of the suture course or of an incorrect position, is achieved by a suture system (1) with a needle-like applicator (2, 22, 42) having a tip (26, 50) in its front end area, with a surgical suture material (4, 24, 44) provided with barbs (6, 7, 28, 29, 47, 48) which, on one side, preferably point in one direction of action from a reference point (8, 30, 49) and, on the other side, point in the opposite direction of action from the reference point (8, 30, 49) and are designed to block a movement of body tissue (12) away from the reference point (8, 30, 49), and with a sheath (3, 23, 43) whose front end area starts from the rear end area of the applicator (2, 22, 42) and which surrounds the surgical suture material (4, 24, 44).
