Abstract
Abstract Prophylactic devices, including devices for assisting and establishing and maintaining male erectile function, are disclosed. Devices and methods for facilitating male erectile function include open ended elastic sheaths having a plurality of woven strands in open weave configuration wherein the strands are movable longitudinally and individually of one another, with the sheath causing selective constriction around and/or along selected portions of the penis by differential external pressures applied to said selected portions so as to not impede arterial blood flow to the penis but impede venous blood flow from the penis and thereby establish and maintain the penis in an erectile position. Forms are also disclosed wherein venous blood flow is selectively impeded by the device having circumferentially disposed tapered portions or by having less elasticity or thickened chambers in some portions. Other devices are also disclosed including condoms with liquid retaining chambers for dispensing medication or the like.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
118 words
A device for assisting in establishing and maintaining male erectile function comprising: an elastic open ended sheath adapted to fit onto a flaccid or partially flaccid penis; and a plurality of woven strands in said sheath, the length and arangement of said woven strands being based on the diameter of the penis to realize in the penis when erectile a selective constriction around and/or along selected portions of the penis to not impede arterial blood flow to the penis but impede venous blood flow from the penis and thereby maintain the penis in an erectile condition, said woven strands being in the form of an open weave so that said strands can move individually relative to one another.
Claim 2
Independent Claim
118 words
A device for assisting in establishing and maintaining male erectile function comprising: an elastic open ended sheath adapted to fit onto a flaccid or partially flaccid penis; and a plurality of woven strands in said sheath, the length and arangement of said woven strands being based on the diameter of the penis to realize in the penis when erectile a selective constriction around and/or along selected portions of the penis to not impede arterial blood flow to the penis but impede venous blood flow from the penis and thereby maintain the penis in an erectile condition, said woven strands being in the form of an open weave so that said strands can move individually relative to one another.
Claim 3
Dependent Claim
20 words
The device of claim 1 wherein said woven strands are interwoven both longitudinally on and axially around said elastic sheath.
Claim 4
Dependent Claim
17 words
The device of claim 1 wherein said woven strands are interwoven only longitudinally on said elastic sheath.
Claim 5
Dependent Claim
17 words
The device of claim 1 wherein said woven strands are interwoven only axially around said elastic sheath.
Claim 6
Dependent Claim
11 words
The device of claim 1 wherein said woven strands are hollow.
Claim 7
Dependent Claim
11 words
The device of claim 1 wherein said woven strands are solid.
Claim 8
Dependent Claim
30 words
The device of claim 1 wherein at least a first portion of said woven strands have a diameter varied from the diameter of a second portion of said woven strands.
Claim 9
Dependent Claim
28 words
The device of claim 1 wherein said woven strands form a weave, said weave having a circumference around said sheath which varies along the length of said sheath.
Claim 10
Independent Claim
122 words
A device for assisting in establishing and maintaining male erectile function comprising: an open ended elastic sheath adapted to fit onto a flaccid or partially flaccid penis, said elastic sheath comprising a plurality of woven strands in an open weave configuration, the length and arrangement of said strands being such as to permit the strands to move longitudinally individually one another, the sheath causing in the penis when erectile a selective constriction around and/or along selected portions of the penis by differential external pressures applied to said selected portions of the penis so as to not impede arterial blood flow to the penis but impede venous blood flow from the penis and thereby establish and maintain the penis in an erectile condition.
Claim 11
Independent Claim
122 words
A device for assisting in establishing and maintaining male erectile function comprising: an open ended elastic sheath adapted to fit onto a flaccid or partially flaccid penis, said elastic sheath comprising a plurality of woven strands in an open weave configuration, the length and arrangement of said strands being such as to permit the strands to move longitudinally individually one another, the sheath causing in the penis when erectile a selective constriction around and/or along selected portions of the penis by differential external pressures applied to said selected portions of the penis so as to not impede arterial blood flow to the penis but impede venous blood flow from the penis and thereby establish and maintain the penis in an erectile condition.
Claim 12
Independent Claim
182 words
The method of assisting in the establishment and maintenance of male penis erectile function, comprising: selecting for installation on a flaccid or partially flaccid penis an erectile facilitator in the form of an elastic sheath of a nominal length and diameter to realize in the penis when erect a selective differential pressure constriction around and/or along selected portions of the penis, said facilitator being characterized by having portions thereof made up of woven strands interwoven yet individually relatively movable in directions extending in both longitudinal and circumferential directions in the sheath so as to be subject to elongation and/or expansion thereof responsive to increases in size of portions of the penis; installing said sheath on the flaccid or partially flaccid penis; and maintaining said sheath in position on the penis while maintaining arterial blood flow to the penis, with selective constrictions of selective portions of the penis by the sheath acting to not impede arterial blood flow to the penis but impede venous blood flow from the penis and thereby enable the establishment and maintenance of the penis in an erectile condition.
Claim 13
Independent Claim
182 words
The method of assisting in the establishment and maintenance of male penis erectile function, comprising: selecting for installation on a flaccid or partially flaccid penis an erectile facilitator in the form of an elastic sheath of a nominal length and diameter to realize in the penis when erect a selective differential pressure constriction around and/or along selected portions of the penis, said facilitator being characterized by having portions thereof made up of woven strands interwoven yet individually relatively movable in directions extending in both longitudinal and circumferential directions in the sheath so as to be subject to elongation and/or expansion thereof responsive to increases in size of portions of the penis; installing said sheath on the flaccid or partially flaccid penis; and maintaining said sheath in position on the penis while maintaining arterial blood flow to the penis, with selective constrictions of selective portions of the penis by the sheath acting to not impede arterial blood flow to the penis but impede venous blood flow from the penis and thereby enable the establishment and maintenance of the penis in an erectile condition.
Claim 14
Dependent Claim
70 words
The method of claim 10, comprising applying selective differential pressure to a portion of the penis not relatively as erectile as other portions thereof by engaging such less erectile penis portion with a portion of the sheath which is less elastic than other portions with the result that greater external pressure is applied to said relatively less erectile penis portion than is applied to said other portions of the penis.
