METHODS AND SYSTEMS FOR CHEMICAL ABLATION

摘要

Thermochemical ablation techniques may provide ablation of bodily tissue using chemical reaction energy.

主权项

1. A thermochemical ablation system, comprising:
a percutaneous fluid delivery cannula comprising first and second lumens extending from a proximal portion to a distal portion, the distal portion comprising a first side port in fluid communication with at least the first lumen and a second side port in fluid communication with at least the second lumen; a first reservoir that contains a reducing agent so as to communicate the reducing agent through the first lumen to the distal portion of the percutaneous fluid delivery cannula, at least a portion of the reducing agent being deliverable out of the first side port; and a second reservoir that contains an oxidizing agent so as to communicate the oxidizing agent through the second lumen to the distal portion of the percutaneous fluid delivery cannula, at least a portion of the oxidizing agent being deliverable out of the second side port to react with the reducing agent at the distal portion and generate an exothermic redox reaction.
