  • Publication number: 20230414342
    Abstract: A breast implant or tissue expander includes an implant shell having an inner chamber and a tube detachably connected with the implant shell. The tube has a first lumen that is in fluid communication with the inner chamber for adding fluid into the inner chamber to increase the size of said implant shell or for removing fluid from the inner chamber to reduce the size of the implant shell. The tube has a second lumen and one or more lateral openings in fluid communication with the second lumen for draining fluid that collects in tissue surrounding the implant shell. The breast implant has a fluid inlet opening formed in the implant shell, and a valve disposed within the fluid inlet opening. The valve is normally biased into a closed position, and is opened by inserting the distal end of the tube into the fluid inlet opening.

  • Patent number: 11844687
    Abstract: A method of making an implantable prosthesis includes applying a gelling enhancer layer over an inner surface of a wall of a silicone shell having anterior and posterior walls surrounding an interior volume. The method includes filling the interior volume of the shell with a silicone gel and curing the silicone gel. The cured silicone gel that is located within a zone that is in the vicinity of the gelling enhancer layer has a higher level of cohesiveness than the cured silicone gel that is located outside the zone. The zone of the silicone gel having the higher level of cohesiveness has a thickness of 2-10 mm. The silicone gel located outside the zone has a first concentration level of a gelling enhancer and the silicone gel located within the zone has a second concentration level of the gelling enhancer that is 5%-300% greater than the first concentration level.

  • Publication number: 20220395643
    Abstract: A gas sterilizable syringe includes an enclosure having walls that define a fluid chamber. A flowable material is disposed within the fluid chamber of the enclosure. A plunger is assembled with the enclosure and is moveable toward a distal end of the enclosure for dispensing the flowable material. One or more apertures are formed in at least one of the walls of the enclosure. A gas permeable barrier covers at least one of the apertures formed in at least one of the walls of the enclosure for enabling sterilization gases to pass through the at least one aperture covered by the gas permeable barrier while preventing the flowable material from passing through the at least one of aperture. The gas permeable barrier is permeable to the sterilization gases and impermeable to the flowable material disposed within the fluid chamber of the enclosure.
