Abstract
Abstract A compound prosthesis for surgical implantation is provided that has an elastic sack or envelope which is adapted to contain a foam core and a quantity of a liquid in the cells of the core. The envelope has a flexible tube for adding the liquid at the time of implantation so that the size of the implant can be adjusted as desired. The flexible tube can then be tied off and concealed in a pocket in the outer layer of foam or sponge material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
118 words
A surgical female breast prosthesis comprising: a pliable, foamed plastic, open cell, porous core of normal breast-simulating form, having a generally flat base, and an apex; said core having deep slits in spaced planes which are generally longitudinally disposed relative to an axis that intersects the centraL portion of the base and the apex of said core, said slits terminating short of the apex of the core at one end and short of the base of the core at the other; and a fluid impervious elastomeric sac disposed closely about said core; said core being adapted to hold a liquid within its pores and slits, and said pores and slits affording mobility for said liquid within said core.
Claim 2
Dependent Claim
118 words
A surgical female breast prosthesis comprising: a pliable, foamed plastic, open cell, porous core of normal breast-simulating form, having a generally flat base, and an apex; said core having deep slits in spaced planes which are generally longitudinally disposed relative to an axis that intersects the centraL portion of the base and the apex of said core, said slits terminating short of the apex of the core at one end and short of the base of the core at the other; and a fluid impervious elastomeric sac disposed closely about said core; said core being adapted to hold a liquid within its pores and slits, and said pores and slits affording mobility for said liquid within said core.
Claim 3
Dependent Claim
23 words
The prosthesis of claim 1, wherein said slits are in angularly spaced planes which are generally radially disposed in relation to said axis.
Claim 4
Dependent Claim
26 words
The prosthesis of claim 2, wherein at least some of the slits extend only part way from the exterior surface of the core to said axis.
Claim 5
Dependent Claim
22 words
The prosthesis of claim 2, wherein at least some of the slits extend from the exterior of the core to said axis.
Claim 6
Dependent Claim
45 words
The prosthesis of claim 2, wherein at least some of the slits extend inwardly from one location on the exterior surface of the core to the general region of said axis, and thence therebeyond to an opposite location on the external surface of the core.
