Abstract
A catheter for insertion into a cavity, duct, or vessel to permit injection or withdrawal of fluids or to establish patency of a passageway comprises an elongated tubular catheter body having a distal end and a proximal end and an outer diameter, a drainage lumen extending through the catheter body from the distal end to the proximal end, the drainage lumen communicating with an opening in the catheter body at the distal end of the catheter body, an inflation lumen formed in the catheter body, and one or more of the following: a) inflatable tube sections disposed on the catheter body at the distal end of the catheter body for securing the distal end of the catheter body in a desired location when the tube sections are inflated, b) a valve connected to the inflation lumen for permitting backflow of the inflation fluid from the inflation lumen through the valve when a pre-set pressure value is reached, and c) a hollow reservoir for holding a pre-determined volume of inflation fluid.
