Abstract

The present invention relates to a system and method utilizing cryogenic cooling in an angioplasty balloon catheter (100) for treatment of arterial stenosis and prevention of restenosis. More particularly, the present invention relates to an angioplasty balloon catheter (100) utilizing expansion of compressed gas to effect Joule-Thomson cooling of an angioplasty balloon (110), and optionally further incorporating external temperature sensors to identify a locus for treatment of arterial stenosis. The present invention further relates to angioplasty treatment systems incorporating such a catheter, and to cryogenic angioplasty methods for treating arterial stenosis and discouraging restenosis.
