1. A balloon catheter comprising:
- a catheter body having a first end and a second end and comprising at least one channel and an opening;
a balloon forming a chamber, the chamber in fluid communication with the opening in the catheter body; and
a thermal element disposed in communication with the balloon for heating fluid, the thermal element comprising a ferromagnetic heating element in the form of a ferromagnetic coil.

Abstract
Thermally adjustable surgical tools include a conductor and a ferromagnetic material. The ferromagnetic material may be quickly heated when subjected to high frequency alternating current through the conductor. The ferromagnetic material may also cool rapidly because of its relatively low mass and the small thermal mass of the conductor. The thermally adjustable surgical tools may be used to sculpt, melt, break and/or remove biological material. The thermally adjustable surgical tools may also include balloon catheters which can heat fluid to thereby treat biological material.

14. A method for treating biological material, the method comprising:
-
selecting a catheter body having a fluid channel, a balloon disposed along the catheter body in fluid communication with the fluid channel, and a ferromagnetic heating element disposed so as to be in contact with the fluid contained within the balloon catheter for heating the fluid, wherein the ferromagnetic heating element comprises a ferromagnetic coil; passing fluid through the catheter body and into the balloon;
wherein the fluid is brought into contact with the thermal element to heat the fluid; andcontacting the biological material with the balloon. - View Dependent Claims (15)
