ABSTRACT:
A method for inhibiting the restenosis of blood vessel walls after angioplasty, including the application of low grade heat to the vessel walls. A heat applying perfusion catheter is advanced to a recently dilatated vessel region. Heat is applied to the region walls to inhibit restenosis. A preferred temperature range is from 42 to 45 degrees C. A preferred time period for treatment is from 3 to 6 minutes. A perfusion catheter allows longer heat treatment times. Electrical resistance heat, radio frequency current passage through inflation fluid, and microwave radiation are all heat sources within the scope of the invention.
