Abstract: The invention relates to an external penile prosthesis or device which is designed to stimulate a couple's sexual pleasure during vaginal intercourse. The inventive device has been designed ergonomically on anatomical/physiological bases that are related to the erogenous zones of the male and female genitals. The device consists of a duckbill-shaped head, three ventral rings and a posterior appendage. According to the invention, each of said components performs a particular, specific function. The device is used by the man during vaginal intercourse after it has been duly positioned on the external genitals, such that the above-mentioned head lies longitudinally against the dorsal face of the erect penis where it is fixed in place by the distal, central and proximal rings. The proximal ring is placed around the root of the penis, behind the scrotal sac, such that the semi-spherical posterior appendage remains in contact with the perianal skin of the user.

Abstract: An intra-vas deferens occlusive device for male contraception includes an axial filament having a small identification ball at the proximal end thereof, which remains outside the vas deferens but which is joined to an anchoring filament and to two occlusive bodies essentially in the form a clamp. The occlusive bodies are joined in a first embodiment by the interconnecting filament and in a second embodiment by the vertices thereof, such as to form a peripheral slit. Both embodiments terminate in a flange which is assembled to a washer pivot of the ad hoc insertion and implantation needle of the device.
