Abstract
An improved self contained automatic bladder control device includes a valve assembly mount for releasable receiving a valve assembly. The preferably cylindrical mount has a textured outer surface designed to interact with urethral tissue. Thus the mount can be placed nonsurgically into a urethra and in time it will be held against movement by the tissue interaction with the textured outer surface, yet the mount will still be removable without surgery. Two embodiments of valve assemblies are disclosed, each of which provides a sphincter-like operation of the bladder control apparatus. A first embodiment is designed to use Bernoulli's law to hold open the valve apparatus after a short period of muscle contraction. The second embodiment is designed to use the fact that the force generated by hydrostatic pressure is directly related to the area on which it impinges, to accomplish the desired valve holding period.
