Endosphincter, set for releasable closure of the urethra and method for introduction of an endosphincter into the urethra
First Claim
1. Artificial endosphincter for the urethra, with a retaining part and a valve body that can be secured by the latter in the urethra, with a valve that can be operated manually from the outside by exerting pressure, wherein the retaining part has a cylindrical main body with a first diameter D, and at one end thereof, a likewise cylindrical end section with a smaller second diameter d, and wherein said main body of said retaining part and said cylindrical end section thereof have an expanding retaining area for said valve body permanently connecting them together and wherein the retaining part has openings in its jacket wall to secure said valve body in the urethra.

- 1. Artificial endosphincter for the urethra, with a retaining part and a valve body that can be secured by the latter in the urethra, with a valve that can be operated manually from the outside by exerting pressure, wherein the retaining part has a cylindrical main body with a first diameter D, and at one end thereof, a likewise cylindrical end section with a smaller second diameter d, and wherein said main body of said retaining part and said cylindrical end section thereof have an expanding retaining area for said valve body permanently connecting them together and wherein the retaining part has openings in its jacket wall to secure said valve body in the urethra.
- 19. Set for releasable closure of the urethra comprising a retaining part, a valve body that can be secured in the urethra by said retaining part and a device for introduction of said valve body into the urethra, wherein said retaining part has a cylindrical main body with a first diameter D and, at one end thereof, a likewise cylindrical end section with a smaller second diameter d, and wherein said main body of retaining part and said end section thereof have a retaining area for said valve body that expands and permanently connects them together, and wherein said device for introduction of said valve body has a stop as a backing device for said valve body and an outer cannula tube surrounding said stop and receiving said valve body, said cannula being capable of being retracted relative to said stop to release the valve body from the cannula tube.
- 22. Method for introducing an endosphincter into the urethra, comprising the steps of providing a device having introducing elements for introducing the endosphincter into the urethra through the urethral opening, said introducing elements receiving the endosphincter consisting of a valve body and a retaining part permanently connected therewith, introducing said introducing elements into the urethra up to the vicinity of the pelvic floor and then pulling backward in the direction of the urethral opening relative to a steadying device for the endosphincter an outer cannula tube holding the endosphincter as part of the introducing elements, whereupon a retaining part initially emerges from the outer cannula tube and, because of its intrinsic elasticity, expands radially at human body temperature and becomes retained in the vicinity of the pars membranacea of the urethra and as the cannula tube is pulled further backward, the entire endosphincter is opened.

26. Method for introduction of an artificial endosphincter into the urethra, comprising the steps of providing a device having introducing elements, containing a retaining part for introduction elements, containing a retaining part, for introduction of the endosphincter into the urethra, introducing said introducing elements through the urethral opening into the urethra up to the vicinity of the pelvic floor and releasing in the vicinity of the pelvic floor an outer cannula tube containing the retaining part, while backing the retaining part with a steadying device, so that the retaining part, by elastic radial expansion at body temperature, is retained in the vicinity of the pars membranacea of the urethra, removing said introducing elements for the retaining part, introducing introducing elements, containing a valve body, of a device for the introduction of the valve body through the urethral opening into the urethra up to a point in front of an outer tapering end section of the retaining part so that a retaining section of the valve body is introduced through the tapered end section of the retaining part into a retaining area of the retaining part.
