Abstract
This invention provides a releasable balloon catheter having a portion cuttable by torsion or a portion cuttable by heating at or near a joint part between the catheter body and the balloon. When the balloon catheter is inserted into a vessel and carried to the desired site by the blood stream and the balloon is inflated by introducing a fluid into the balloon and is fixed at the desired site face-to-face with the wall of the vessel, torsion or heating causes the balloon to be released from the catheter body. The balloon catheter is used to embolize vascular lesions.
