CATALYZED EXOTHERMIC ABLATION DEVICE

摘要

The invention relates to devices, systems, and methods for heating tissue, including ablating a tumor, using the catalyzed heat of decomposition of hydrogen peroxide solutions. A hydrogen peroxide solution is contacted with a catalyst to decompose the hydrogen peroxide and heat the distal tip of a catheter to a temperature effective to ablate a target tissue.

主权项

1. A system for catalyzed exothermic heating of tissue comprising:
a source of hydrogen peroxide solution; a source of neutralizing solution; a catalyst in fluid communication with the source of hydrogen peroxide; and a catheter, the catheter comprising a proximal end, a distal end, a distal tip, and an enclosed heat chamber located at the distal end of the catheter, the enclosed heat chamber being in fluid communication with the catalyst and the source of neutralizing solution.
