  • Patent number: 5250025
    Abstract: A percutaneous access catheter is employed for examining and treating internal body cavities and organs via an access tract. For example, the catheter can be employed for examining and treating the gallbladder via a transhepatic tract. The examination may employ endoscopic, fluoroscopic, ultrasonic, or other techniques; the treatment may employ surgical, chemical, or physical modalities. The catheter includes two inflation elements. These inflation elements control hemorrhaging and leakage of fluids from the internal body cavity or organ and reduce migration of the catheter within the internal body cavity or organ during the examination and/or treatment. The first inflation element is a toroidal elastic balloon located at the distal end of the device which serves to restrict the accidental or unintended removal of the distal end from the internal body cavity or organ.
