Abstract
Abstract An artificial breast form to be worn externally on the body of a woman, not implanted in the body, constructed from preformed, self-contained, stable gel structure of breast compatible size and shape and covered with a porous elastic fabric cover which does not normally constrain the gel.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
35 words
An artificial breast form comprising: a. a preformed self-contained stabilized gel structure of breast size and shape, and b. a porous elastic fabric cover which yields in response to pressures exerted thereon by said gel.
Claim 2
Dependent Claim
35 words
An artificial breast form comprising: a. a preformed self-contained stabilized gel structure of breast size and shape, and b. a porous elastic fabric cover which yields in response to pressures exerted thereon by said gel.
Claim 3
Dependent Claim
45 words
The combination set forth in claim 1 in which said gel is a silicone gel, the reaction product of a methyl polysiloxane containing silicone-bonded vinyl groups and methyl polysiloxane containing SiH groups which has been catalyzed by platinum to establish and substantially retain said shape.
Claim 4
Dependent Claim
33 words
The combination set forth in claim 1 in which said gel is a dielectric silicone gel catalyzed to stably retain substantially said shape and coated with powder to avoid sticking to said cover.
Claim 5
Dependent Claim
34 words
The combination set forth in claim 1 in which a layer of a porous elastic fabric is impregnated with said gel and positioned as a subsurface layer beneath the posterior surface of said structure.
Claim 6
Dependent Claim
27 words
The combination set forth in claim 4 in which said porous elastic fabric cover is secured at the edges thereof to the edges of said impregnated layer.
Claim 7
Dependent Claim
27 words
The combination set forth in claim 4 in which said porous elastic fabric cover is stitched at the edges thereof to the edges of said impregnated layer.
Claim 8
Dependent Claim
20 words
The combination set forth in claim 1 in which said structure is powder coated to prevent sticking to said cover.
Claim 9
Dependent Claim
26 words
The combination set forth in claim 1 in which said structure is in the form of a complete breast to be used by a mastectomy patient.
Claim 10
Dependent Claim
28 words
The combination set forth in claim 1 in which said structure is in the form of an uplift pad to be worn in enhancement of a natural breast.
Claim 11
Independent Claim
84 words
The method of forming a female breast form which comprises: a. impregnating a porous elastic fabric panel with a silicone and immersing said panel in the rear surface portion of a breast shaped body of said silicone as it is catalyzed to form a self-contained stabilized gel structure of breast size and shape, b. coating said structure with a powder to render the surfaces thereof nontacky, and c. applying over all surfaces of said structure a multi layer cover of a porous elastic fabric.
Claim 12
Independent Claim
84 words
The method of forming a female breast form which comprises: a. impregnating a porous elastic fabric panel with a silicone and immersing said panel in the rear surface portion of a breast shaped body of said silicone as it is catalyzed to form a self-contained stabilized gel structure of breast size and shape, b. coating said structure with a powder to render the surfaces thereof nontacky, and c. applying over all surfaces of said structure a multi layer cover of a porous elastic fabric.
Claim 13
Dependent Claim
16 words
The method of claim 10 in which said cover is secured to said immersed fabric panel.
Claim 14
Dependent Claim
17 words
The method of claim 11 in which said cover is edged stitched to said immersed fabric panel.
