Abstract
A closure device for a male urethra, which is formed by an elongated valve device to be inserted into the urethra and to be releasably fastened therein. The elongated object may be formed by a single basic body element, or by a basic body element combined with at least one intermediate element and an end element. The valve is open at both ends and includes a longitudinal through hole. The valve body, at least on its front end, includes a removable closure plug. The valve body is partly enclosed by a double-membrane tube that can be pressurized and expanded to secure the device within the urethra. The basic body element of the valve body is provided with at least one radial hole to permit the introduction of fluid such as air into a space between an inner and outer membrane which comprise the double membrane tube or sleeve. An opening provided in the inner sleeve is offset relative to the radial opening in the valve body. In this way, after air or other fluid is supplied to the space between the membranes, the inner membrane will seal the radial opening in the valve body. A hand pump is provided to supply as well as release air from the valve body.
