Abstract
Abstract A six-way acting vaginal contraceptive having a body of spongelike resilient compressible absorbent material, the body being initially compressed on one axis by a string and on the other axis by a band to form two bifurcated butterfly ends which in turn form a pair of barriers across the vaginal canal, the inner barrier being adapted to lie against the cervix of the uterus and the edges of the butterfly ends being adapted to block the vaginal fornices. The barrier ends are impregnated with a spermicide and at least one end may be impregnated with a coital lubricant.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
A contraceptive having a flexible, compressible elastic, resilient sponge-like body and comprising: a band located substantially centrally of said body; and compressing said body at said band; said body flaring on each side of said central band, said body being additionally compressed at an axis substantially normal to that of said band; the flaring portions of said body on each side of said band being thereby bifurcated to form a butterfly arrangement; a string; said string effecting said additional compression; an end of said string passing between said bifurcated portion of the body on one side and extending beyond the boundary of the body.
Claim 2
Dependent Claim
104 words
A contraceptive having a flexible, compressible elastic, resilient sponge-like body and comprising: a band located substantially centrally of said body; and compressing said body at said band; said body flaring on each side of said central band, said body being additionally compressed at an axis substantially normal to that of said band; the flaring portions of said body on each side of said band being thereby bifurcated to form a butterfly arrangement; a string; said string effecting said additional compression; an end of said string passing between said bifurcated portion of the body on one side and extending beyond the boundary of the body.
Claim 3
Dependent Claim
16 words
The contraceptive of claim 1 in which at least one end is impregnated with a spermicide.
Claim 4
Dependent Claim
38 words
The contraceptive of claim 1 wherein the original body prior to the placement of the string and band thereon is substantially cubic in shape, the edge of said cube having a dimension of the order of 3 inches.
Claim 5
Dependent Claim
49 words
A contraceptive having a flexible, compressible elastic, resilient sponge-like body and comprising: a band located substantially centrally of said body; and compressing said body at said band; said body flaring on each side of said central band; at least one end of said body being impregnated with a spermicide.
Claim 6
Dependent Claim
49 words
A contraceptive having a flexible, compressible elastic, resilient sponge-like body and comprising: a band located substantially centrally of said body; and compressing said body at said band; said body flaring on each side of said central band; at least one end of said body being impregnated with a spermicide.
Claim 7
Dependent Claim
49 words
A contraceptive having a flexible, compressible elastic, resilient sponge-like body and comprising: a band located substantially centrally of said body; and compressing said body at said band; said body flaring on each side of said central band, at least one end of said body being impregnated with a lubricant.
Claim 8
Dependent Claim
49 words
A contraceptive having a flexible, compressible elastic, resilient sponge-like body and comprising: a band located substantially centrally of said body; and compressing said body at said band; said body flaring on each side of said central band, at least one end of said body being impregnated with a lubricant.
Claim 9
Dependent Claim
69 words
A contraceptive device having a flexible compressible sponge-like body and comprising a pair of flaring ends and a section of lesser cross-sectional dimension between the flaring ends, and a string surrounding said portion having a lesser cross-sectional dimension; said string having an extension beyond said sponge-like body, one of said flaring ends being impregnated with a spermicide and the other of said flaring ends being impregnated with a lubricant.
Claim 10
Dependent Claim
69 words
A contraceptive device having a flexible compressible sponge-like body and comprising a pair of flaring ends and a section of lesser cross-sectional dimension between the flaring ends, and a string surrounding said portion having a lesser cross-sectional dimension; said string having an extension beyond said sponge-like body, one of said flaring ends being impregnated with a spermicide and the other of said flaring ends being impregnated with a lubricant.
