Abstract
Abstract A condom having a plurality of deformable sealed chambers along at least a portion of the length thereof, rheopexic fluid being filled in the deformable sealed chambers. When the chambers are deformed during use of the condom, shear stress is applied to the rheopexic fluid due to deformation of the sealed chambers to cause the rheopexic fluid to increase its consistency as a function of increasing shear stress applied thereto, thereby providing a stiffening effect to the condom.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
111 words
A condom comprising: means defining an elongated generally tubular member of thin, flexible material, said tubular member having a closed and open end; means defining a plurality of deformable sealed chambers along the length of at least a portion of said tubular member; and rheopexic fluid filled in said plurality of deformable sealed chambers such that when said deformable sealed chambers are deformed during use of the condom in intercourse, shear stress is applied to said rheopexic fluid due to deformation of said sealed chambers to cause said rheopexic fluid to increase its consistency as a function of increasing shear stress applied thereto, thereby providing a stiffening effect to the condom.
Claim 2
Dependent Claim
111 words
A condom comprising: means defining an elongated generally tubular member of thin, flexible material, said tubular member having a closed and open end; means defining a plurality of deformable sealed chambers along the length of at least a portion of said tubular member; and rheopexic fluid filled in said plurality of deformable sealed chambers such that when said deformable sealed chambers are deformed during use of the condom in intercourse, shear stress is applied to said rheopexic fluid due to deformation of said sealed chambers to cause said rheopexic fluid to increase its consistency as a function of increasing shear stress applied thereto, thereby providing a stiffening effect to the condom.
Claim 3
Dependent Claim
54 words
The condom of claim 1, wherein said means defining said deformable sealed chambers comprises an outer layer around at least a portion of the length of said tubular member and being sealed to said tubular member at portions thereof to define said plurality of sealed chambers, said outer layer being of thin, flexible material.
Claim 4
Dependent Claim
37 words
The condom of claim 1 or claim 2, wherein said means defining said elongated tubular member and said means defining said plurality of chambers each comprise a thin, flexible layer of copolymers of vinylidene fluoride and hexafluoropropylene.
Claim 5
Dependent Claim
29 words
The condom of claim 1 or claim 2, wherein at least one of said means defining said tubular member and means defining said sealed chambers is made of lambskin.
Claim 6
Dependent Claim
29 words
The condom of claim 1 or claim 2, wherein at least one of said means defining said tubular member and means defining said sealed chambers is made of latex.
Claim 7
Dependent Claim
32 words
The condom of claim 4, wherein said tubular member and said means defining said sealed chambers comprises a material which is fluid-tight to said rheopexic material laminated or bonded to said lambskin.

The condom of claim 9, wherein said laminated material comprises aluminum foil.
Claim 13
Dependent Claim
35 words
The condom of claim 1 or claim 2, wherein at least one of said means defining said tubular member and said means defining said plurality of chambers is made of a thin layer of polyethylene.
Claim 14
Dependent Claim
36 words
The condom of claim 1 or claim 2, wherein at least one of said means defining said tubular member and said means defining said plurality of chambers is made of a thin layer of polypropylene glycol.
Claim 15
Dependent Claim
32 words
The condom of claim 1 or claim 2, wherein said deformable sealed chambers are distributed around the circumference of said tubular member over said portion of the length of said tubular member.
Claim 16
Dependent Claim
37 words
The condom of claim 14, wherein said deformable fluid chambers are elongated sealed chambers oriented in the direction of the length of said tubular member, adjacent sealed chambers being offset or staggered with respect to each other.
Claim 17
Dependent Claim
105 words
A penis stiffening device comprising: means defining an elongated generally tubular member of thin, flexible material; means defining at least one deformable sealed chamber in said elongated tubular member; rheopexic fluid filled in said at least one deformable sealed chamber such that when said deformable sealed chamber is deformed during use, shear stress is applied to said rheopexic fluid due to deformation of said sealed chamber to cause said rheopexic fluid to increase its consistency as a function of increasing shear stress supplied thereto, thereby providing a stiffening effect to said elongated tubular member; and means for coupling said elongated tubular member to a penis.
Claim 18
Dependent Claim
105 words
A penis stiffening device comprising: means defining an elongated generally tubular member of thin, flexible material; means defining at least one deformable sealed chamber in said elongated tubular member; rheopexic fluid filled in said at least one deformable sealed chamber such that when said deformable sealed chamber is deformed during use, shear stress is applied to said rheopexic fluid due to deformation of said sealed chamber to cause said rheopexic fluid to increase its consistency as a function of increasing shear stress supplied thereto, thereby providing a stiffening effect to said elongated tubular member; and means for coupling said elongated tubular member to a penis.
Claim 19
Dependent Claim
30 words
The penis stiffening device of claim 16, wherein said generally tubular member comprises a plurality of deformable sealed chambers, rheopexic fluid be filled in said plurality of deformable sealed chambers.
