Patent ID: 7967811

Claim:
A catheter assembly, comprising: an elongated catheter body including a hollow tube having proximal and distal ends, the distal end including a drainage eye for draining fluid from the distal end through the tube to the proximal end thereof, an inflation lumen extending from the proximal end thereof through at least a portion of the catheter body and terminating at a forward end portion of the body in an aperture for passing fluid outwardly from and into the lumen, and a balloon forming membrane secured in covering relation with the aperture, the membrane being radially expandable in response to positive pressure on fluid passed through the interior of the inflation lumen, a fluid regulating valve provided with an inlet and an outlet and a manually operable closure member, the outlet being fluidly connected to the aperture in the inflation lumen and the closure member mounted for movement transverse across the tube between open and closed positions, respectively, for permitting and preventing fluid to pass between the inlet and the outlet and into or from the inflation lumen, the valve including a fluid impermeable material housing and having an interior chamber, a supply tube having an inlet and outlet exterior to and interior of the chamber, a generally planar valve plate having a circular shaped central opening, the interior diameters of the tubes and the diameter of the central opening being substantially the same, the axes of the tubes being coaxially aligned with one another and in coaxial relation with the center of the central opening, and a manually operable aspirator pump fluidly connected to the inlet, said aspirator comprising a generally cylindrical bellows of the pleated type, having opposite ends and axially collapsible, and defining a variable volume hollow interior chamber.
