Abstract The improved catheter has a tubular body or stem that is apertured at its forward end or tip and is surrounded by an encircling jacket for a substantial portion of its length. A fluid feed tube leads into the jacket for the supply of a fluid thereinto, the jacket having a foraminous area, controllable in size situated adjacent to its forward end and through which area the fluid is emitted for direct treatment at the walls of a body orifice, or any cavity or opening in which the catheter is inserted. A tube for transmission of liquid or air extends longitudinally of the catheter body under the jacket and is in communication with an inflatable chamber located beyond the foraminous area of the jacket and rearwardly of the forward tip of the catheter body, said inflatable body, when filled with liquid furnished by said transmission tube, acting to retain the catheter in place in the body orifice or opening.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
124 words
A catheter having a body or stem of tubular form provided with a tip at its forward end, an inflatable body encircling the tube adjacent to the tip end thereof, a fluid-supply passage for liquid or air entering into and extending along the tube in communication with the inflatable body to inflate the same within a body opening, a jacket encircling the tube and provided with a pervious portion through which liquid-carrying medicaments may pass out from within the jacket, said jacket having a tightfitting elastic sleeve rollable from the outer toward the inner end of the pervious portion to control the area of medicament flow through said pervious portion, and fluid-supply means for carrying said medicaments connected to the interior of the jacket.
