Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
A male contraceptive device comprising: (a) a urethral sealing member in the form of an elongate hollow tube adapted to be received in a urethra and communicating with the urethra, said tube having, adjacent one end thereof, means to engage the fossa navicularis, said means including a flexible convex annular portion adapted to be displaced outwardly to engage the fossa navicularis in a sealing relationship, and (b) container means mounted on said tube adapted to receive sperm passing from the urethra, said container means being mounted on a threaded member and the interior of said tube defining threads adapted to receive said threaded member whereby the threadable tubular member with said tube serves to expand the flexible convex portion of said tube to effect a sealing relationship between said tube and the fossa navicularis.
Claim 2
Dependent Claim
134 words
A male contraceptive device comprising: (a) a urethral sealing member in the form of an elongate hollow tube adapted to be received in a urethra and communicating with the urethra, said tube having, adjacent one end thereof, means to engage the fossa navicularis, said means including a flexible convex annular portion adapted to be displaced outwardly to engage the fossa navicularis in a sealing relationship, and (b) container means mounted on said tube adapted to receive sperm passing from the urethra, said container means being mounted on a threaded member and the interior of said tube defining threads adapted to receive said threaded member whereby the threadable tubular member with said tube serves to expand the flexible convex portion of said tube to effect a sealing relationship between said tube and the fossa navicularis.
Claim 3
Dependent Claim
119 words
A male contraceptive device comprising: (a) a urethral sealing member in the form of an elongate hollow tube adapted to be received in a urethra and communicating with the urethra, said tube having, adjacent one end thereof, means to engage the fossa navicularis in a sealing relation, and (b) container means mounted on said tube adapted to receive sperm passing from the urethra, said container means including a sleeve member adapted to be received within the said elongate hollow tube whereby pressure on the neck of said sleeve operates to collapse the urethral sealing member and the release of pressure on the neck operates to relax the urethral sealing member to form a sealing relationship with the fossa navicularis.
Claim 4
Dependent Claim
119 words
A male contraceptive device comprising: (a) a urethral sealing member in the form of an elongate hollow tube adapted to be received in a urethra and communicating with the urethra, said tube having, adjacent one end thereof, means to engage the fossa navicularis in a sealing relation, and (b) container means mounted on said tube adapted to receive sperm passing from the urethra, said container means including a sleeve member adapted to be received within the said elongate hollow tube whereby pressure on the neck of said sleeve operates to collapse the urethral sealing member and the release of pressure on the neck operates to relax the urethral sealing member to form a sealing relationship with the fossa navicularis.
Claim 5
Dependent Claim
126 words
A male contraceptive device comprising a urethral sealing member in the form of an elongate hollow tube adapted to be received in a urethra and communicating with the urethra, said tube having, adjacent one end thereof, means to engage the fossa navicularis in a sealing relation, container means mounted on said tube adapted to receive sperm passing from the urethra, said means to engage the fossa navicularis including a flexible convex annular portion adapted to be displaced outwardly to engage the fossa navicularis in a sealing relationship, and the urethral sealing member including an annular locking lip and said container means including an elongate tubular portion having a locking flange adapted to engage the locking lip to secure the container means with the urethral sealing member.
Claim 6
Dependent Claim
126 words
A male contraceptive device comprising a urethral sealing member in the form of an elongate hollow tube adapted to be received in a urethra and communicating with the urethra, said tube having, adjacent one end thereof, means to engage the fossa navicularis in a sealing relation, container means mounted on said tube adapted to receive sperm passing from the urethra, said means to engage the fossa navicularis including a flexible convex annular portion adapted to be displaced outwardly to engage the fossa navicularis in a sealing relationship, and the urethral sealing member including an annular locking lip and said container means including an elongate tubular portion having a locking flange adapted to engage the locking lip to secure the container means with the urethral sealing member.
Claim 7
Dependent Claim
68 words
A device as defined in claim 3 wherein the inner diameter of the urethral sealing member is reduced in the area adjacent to the annular portion of the sealing means so that the insertion of the elongate tubular portion of the container means in the urethral sealing member will forceably expand the annular portion and thereby displace it outwardly to engage the fossa navicularis in a sealing relationship.
Claim 8
Dependent Claim
70 words
A device as defined in claim 3 wherein the container means includes a rigid tubular member adapted to insert in said elongate hollow tube whereby the rigid tubular member operates to create tension on the hollow tube and the release of said tubular member within the urethral sealing member operates to relax the urethral sealing member and thereby create a seal between the urethral sealing member and the fossa navicularis.
Claim 9
Dependent Claim
89 words
A male contraceptive device comprising: (a) a urethral sealing member in the form of an elongate hollow tube adapted to be received in a urethra and communicating with the urethra, said tube having, adjacent one end thereof, means to engage the fossa navicularis in a sealing relation, and a disc portion integral with said tube, said disc portion adapted to overlay the glans to prevent displacement of the hollow tube into the urethra, and (b) container means mounted on said tube adapted to receive sperm passing from the urethra.
Claim 10
Dependent Claim
89 words
A male contraceptive device comprising: (a) a urethral sealing member in the form of an elongate hollow tube adapted to be received in a urethra and communicating with the urethra, said tube having, adjacent one end thereof, means to engage the fossa navicularis in a sealing relation, and a disc portion integral with said tube, said disc portion adapted to overlay the glans to prevent displacement of the hollow tube into the urethra, and (b) container means mounted on said tube adapted to receive sperm passing from the urethra.
