Systems and methods for treating a hollow anatomical structure

摘要

A hollow anatomical structure therapy system comprising:
a heat delivery device suitable for insertion into a blood vessel;
a power source in communication with said heat delivery device, said power source being programmed to:
(a) deliver power to said heat delivery device during a temperature ramp-up phase;
(b) measure time elapsing during power delivery;
(c) monitor operation of said heat delivery device; and
(d) if said operation of said heat delivery device either during or shortly after said temperature ramp-up phase is acceptable, deliver a generally decreasing amount of power to said heat delivery device after said temperature ramp-up phase and maintain a temperature of said heat delivery device within a constant temperature range.
