Abstract
A catheter assembly including a first catheter having distal and proximal ends, and a second catheter which is positionable within the first catheter. The second catheter has a smaller diameter and is more flexible than the first catheter. The second catheter is positionable within the first catheter so that its distal end is extendable beyond the distal end of the first catheter. An expandable balloon or inflatable means is affixed to the outer surface of either the first or second catheters near the distal end thereof. When inflated, the inflatable means sealingly engages the interior walls of a body channel into which the catheter assembly has been inserted. The catheter assembly may also include associated fiber optics for viewing and removing obstructions.
