ABSTRACT:
A balloon catheter comprised a balloon catheter body, a balloon, a main passage and an auxiliary passage. The balloon is provided on the periphery of the tip portion of the catheter body to inflate for blocking a bloodstream at a desired site inside blood vessels. The auxiliary passage is provided for inflating the balloon. The main passage is provided behind the balloon, having an opening to eject a drug. The tip portion of the balloon catheter is inserted into one of branches of the blood vessel near targeted affected part. A fluid is injected into the balloon so that the balloon blocks a bloodstream in the branches. Therefore, a drug is ejected through the main passage of the balloon catheter into other branches.
