ABSTRACT:
A self-inflating urinary catheter which includes a retention balloon has a fluid-filled, unpressurized, deformable reservoir communicating with the balloon. An elastic diaphragm is arranged to squeeze the reservoir against another surface so as to pressurize the fluid, thereby exerting force to expel the fluid from the reservoir to inflate the retention balloon.
