<p>The present invention comprises a safety inflation apparatus for preventing full inflation of a catheter balloon (26) in a small body cavity (82) of lesser internal diameter than that of the fully-inflated catheter balloon (26). The present invention includes a safety reservoir (66) which inflates to absorb excess fluid volume from a catheter inflation device, such as a syringe (40), when the catheter balloon (26). The present invention includes a safety reservoir (66) which inflates to absorb excess fluid volume from a catheter inflation device, such as a syringe (40), when the catheter balloon (26) comes into contact with the wall of the small cavity (82), thereby preventing damage to the cavity wall and injury to the patient. In one embodiment (100) of the invention, sensors and associated electronic displays are employed to provide an indication of the operating state of the system as the catheter balloon (26) is inflated.</p> |
