Radioactive balloon for dilation catheter system and process for preparation thereof

摘要

The present invention relates to a radioactive balloon for angioplasty which is combined with a flexible film containing radionuclides and process for preparation thereof. A balloon dilatation catheter system containing the radioactive balloon can be used in transluminal coronary angioplasty, expanding blood vessel and facilitating the blood flow so as to prevent the proliferation of smooth muscle cell and vascular restenosis efficiently.
