ABSTRACT:
A cleansing catheter for cleaning debris from the fiberoptic window ends of bronchoscopes, other endoscopes and the like, comprises a hollow catheter shaft (26) with an inflatable balloon (28) at one end. A preferred embodiment has a cylindrically shaped balloon (28) with a plurality of small holes (34) through the skin of the balloon arrayed about its annular base so that, when the balloon is filled with liquid, streams of liquid will escape through the holes back along the catheter shaft. In use, the cleansing catheter is advanced, with its balloon end collapsed, through a working channel of a bronchoscope or other endoscope until the balloon end just exits the working channel opening at the lens end of the endoscope. The balloon is then inflated with liquid delivered through the catheter shaft so that streams of liquid from the balloon holes spray against and clean debris from the fiberoptic window of the endoscope.
