  • 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.

  • Patent number: 11712229
    Abstract: A system for dispensing a curable composition includes a dual barrel syringe including a first syringe barrel with a first plunger, and a second syringe barrel with a second plunger. A static mixer is connected with distal ends of the first and second syringe barrels. The first and second plungers are moveable toward the distal ends of the first and second syringe barrels for expelling first and second components of a curable composition from the distal ends of the barrels into the static mixer for mixing the components to form the curable composition. A flexible spreader connected with a distal end of the static mixer has a flat dispensing opening, and a plurality of channels extending to the flat dispensing opening to dispense the curable composition. A hot gas blower generates a hot gas stream flowing distally over the distal end of the flexible spreader for curing the curable composition.
