Abstract

A balloon type catheter used for drainage or irrigation and drainage of a body cavity such as the bladder having a tapered tip with a large elongated lateral opening spanning the approximate distance of the balloon so as to allow complete and maximally effective drainage from the most dependant portion of said body cavity. An inflatable balloon partially surrounds the catheter's distal end, and circumscribingly ending at the lateral borders of the large drainage opening. When the balloon is inflated, the tip of the catheter becomes flush or recessed relative to the balloon thereby preventing the tip from abutting against delicate tissue as to cause compression injury. A gully in the balloon created by the elongated drainage opening act as a vent and buffer the delicate surrounding tissue from negative pressure injury. When used for irrigation and drainage, the catheter has an irrigation conduit that opens at the tip of the catheter to deliver fluid that flushes the cavity and the effluent is drained out via the aforesaid large lateral opening which is designed in this invention to position itself at the lowest portion of said body cavity.
