Abstract: A telemetric in vivo bladder urine monitor system is disclosed. The invention includes a small, buoyant recorder that floats in the bladder of an animal and telemetrically relays data to an external receiver. The invention may be used in measuring urinary tract pressure in diagnosing and treating urinary tract infections, anomalous bladder contraction, etc. The invention may also be used as a monitoring system for bed wetting syndrome, artificial bladders and sphincters.

Abstract: An implantable artificial bladder soft system is provided which comprises an at least partially deformation resistant support base, a compliant deformable diaphragm, an inlet means, an outlet means, an optional outer shell, an optional backflow control means, an optional discharge control means, and an optional anchoring means. This implantable artificial bladder can be completely emptied. A method for the collection of, the storage of and the discharge of biological fluids incorporating the implantable artificial bladder soft system is provided as well.

Abstract: Implantable artificial bladder and method for the collection of, the storage of, or the discharge of biological fluids using the natural peristaltic pressure of a patient's ureter or ureters or of an artifical ureter to fill a first chamber of the artificial bladder and a constant force stored energy means in a second chamber isolated by a rolling diaphragm from the first, said means biasing the rolling diaphragm against the first chamber and serving to empty the implantable artificial bladder.
