Abstract
Abstract A condom is coated on the interior surface with a vasoactive coating, such as a transdermal nitroglycerine coating. As the comdom is fitted onto a penis, contact between the penile tissue and the transdermal nitroglycerine coating increases blood flow through the corpus cavernosum. The resulting increase in blood flow aids the development of a tumescent condition of the penis.

Independent Claim
56 words
A device for stimulating and maintaining an erection comprising, an elastic sleeve-like member which is predeterminedly dimensioned so as to fit onto a penis, said sleeve-like member having an interior surface, and a vasoactive dilator coating on said interior surface for contacting penile tissue and stimulating tumescence when said sleeve-like member is fitted onto the penis.
Claim 2
Independent Claim
56 words
A device for stimulating and maintaining an erection comprising, an elastic sleeve-like member which is predeterminedly dimensioned so as to fit onto a penis, said sleeve-like member having an interior surface, and a vasoactive dilator coating on said interior surface for contacting penile tissue and stimulating tumescence when said sleeve-like member is fitted onto the penis.
Claim 3
Dependent Claim
