Patent attributes
A saline-filled breast prosthesis has enhanced performance by virtue of having tactile characteristics approximating those of gel-filled implants. The invention retains all the benefits of the recognized safety profile, straight-forward construction, and broad clinical indications for saline implants. An enhanced implantable mammary prosthesis comprises a shell, a slurry filler compartment interior to the shell containing slurry filler, a fluid compartment, the fluid compartment being deformable from a neutral profile under pressure from the slurry filler and which recoils to the neutral profile when not under pressure, a reservoir, the reservoir being disposed external to the shell, the reservoir and fluid compartment being fluidically coupled by a port, and a limiting membrane region disposed between the fluid compartment and the reservoir.
