Abstract
An apparatus for and method of selectively occluding a lumen of a multilumen catheter during a medical procedure. The catheter may have any variety of functions of either diagnostic and/or therapeutic nature. A first open lumen to be occluded may have one or more orifices at the distal tip and/or in the side wall of the catheter for infusion of a liquid, injection of a dye, or operation of a guide wire or other control device. A small balloon adjacent the lumen to be occluded is inflated with fluid from a second, closed lumen. Whenever the small balloon is completely inflated, the first, open lumen is occluded. Whenever the small balloon is deflated, the lumen is open to the orifices distal to the small balloon.
