Abstract A tubular prophylactic device and method is disclosed which provides for frictional stimulation of the male penis during copulation while simultaneously serving as an impermeable barrier for the prevention of disease and for birth control purposes. In one form the device consists of a pleated collapsible tube with an extended length from the open end to the closed end of at least approximately twice the length of the erect mature human male penis. The additional length allows the penis to move relative to the prophylactic device during copulation, with the prophylactic device remaining stationary with respect to the wall of the female vagina. In another form the device is characterized by an inwardly folded sleeve that engages the penis and provides for sealing and an excess length that allows for movement of the end of the penis relative to the device when in use. The method is characterized by relative movement between the glans of the penis and the membrane of the device during use thereof.
A tubular prophylactic device formed of flexible, thin impermeable sheet material, having an open end, a closed end and an extended length from the open end to the closed end, characterized by: a. a midsection extending between the open end and the closed end having a circumference sufficiently large to permit movement of an erect male penis within said midsection during coitus, b. a sleeve section formed at the open end having a circumference sufficiently small to fit snugly about the shaft of an erect mature human penis, folded inwardly with respect to the midsection, thereby being disposed inside the device for fixed engagement with the shaft of the penis, and c. a plurality of circumferentially spaced, thin rigid members adhered to the sleeve section on the outer surface thereof between the sleeve section and the midsection to prevent peeling of the sleeve section from the shaft of the penis.

Claim 3
Dependent Claim
48 words
The device of claim 1 wherein the inside of the midsection of the device is lubricated and wherein the inside edge of the sleeve section is closed and releasably sealed to itself thereby separating the lubicated inside of the midsection from the inside surface of the sleeve section.
