A penile ring implant of soft biocompatible material is formed in situ and implanted beneath the skin of the penis of an incontinent male by use of a rod and a probe to form a protuberance which permits the patient to securely attach and easily remove the flexible sheath of the urinary collection device without the assistance of others. A kit for forming and implanting the ring implant includes an elongated D-shaped soft rod, a malleable probe and a connector.

The elastic sheath of a urinary collection device is more securely retained in place upon the penis of an incontinent patient by modifying the patient's penis by making an incision in the penis, implanting penile implants having expansible chambers and a self sealing tip in the corpora cavernosa of the penis, closing the incision and then periodically filling the chambers with fluid introduced through a cannula extending through the glans of the penis and the self sealing tip. The periodic addition of fluid to the chambers causes them to gradually expand and stretch the penile tissue until the penis is larger and firmer and will more securely retain the elastic sheath of the collection device. The implants are especially useful for patients having spinal cord injuries because the implants are soft and not rigid even when filled and therefore they are less likely to erode through the skin of the penis or the urethra.

The invention relates to a prosthetic device for keeping open the lumen of a prostatic urethra. The device includes a body of a physiologically acceptable, perforated, resilient material that can be deformed into a channel-shaped configuration in which it can be inserted into a prostatic urethra. The resilience of the body, together with anchoring formations defined by the body ensures that the device is held secure and can be left indwelling in the prostatic urethra for keeping it open.

An implant device is disclosed for expanding the girth and length of a penis. A soft, flexible body is implanted between the shaft and the skin of the penis. The body takes the shape of a partial cylindrical sleeve that has an outer, relatively elastic sheet member and an inner, relatively inelastic sheet member. When implanted, the body covers the corpus cavernosum of the penis and does not or only partially covers the urethra, and extends in length between the glans penis and the base of the penis. A principally closed sack is formed between the inner and outer sheet members for receiving a fluid under pressure from a fluid source. Spring-like ribs are embedded within the inner sheet member for preventing collapse of the inner sheet member when the body is deflated.

An apparatus for controlling fluid flow within a host body has a first shell and a second shell for coupling with the second shell to form a cylindrical object suitable for engaging and surrounding a selected canal with the host body. The cylindrical object is open at both ends and has an interior diameter of a dimension making it suitable for fitting over the selected host body's canal, such as the urethra. The apparatus also includes a plunger for constricting the fluid flow when activated. The plunger may be activated by an electrical solenoid or hydraulic or pneumatic activation to move from a free-flow position into a constricting position wherein the fluid flow though the canal is substantially prevented or reduced. The apparatus can be used for controlling incontinence or restricting fluid flow in other body canals. The host-user can activate the apparatus with a remote control device outside the body which communicates with the implanted apparatus by means of any wireless communication that transmits a signal to the device causing the solenoid to move the plunger into the constricting position. A second signal causes the plunger to retract into a free-flow position when the user no longer feels the urge to urinate.
