DUAL THERMAL ABLATION DEVICE AND METHOD OF USE

摘要

The invention is a multi-functional ablation device that encompasses the use of both heat energy and cryogenic energy as integrated into one medical device. In one embodiment, the medical device integrates a heat source such as RF or HIFU in combination with a source of cryogenic energy such that the multi-functional ablation device is a dual thermal ablation device capable of utilizing either energy source alone or in combination.

主权项

1. A method for performing tissue ablation comprising:
a longitudinal body having a proximal end and a distal end wherein said proximal end includes an outer sheath having electrical connections contained therein and wherein said distal end is a closed tip with a thermally conductive surface, said thermally conductive surface defining an ablation zone; providing a hybrid thermal-cooling system comprising an electrical power supply and a cooling source configured for integration with said longitudinal body at said proximal end; designating a tissue site for ablation; positioning said ablation zone of said multi-ablation device at a first position of said tissue site; producing heat energy from said electrical power supply; producing cooling energy from said cooling source; directing said heat energy or said cooling energy through said longitudinal body to said ablation zone for a first time period to damage said tissue site; directing said heat energy or said cooling energy through said longitudinal body to said ablation zone for a second time period to damage said tissue site; and removing said ablation zone of said longitudinal body from said tissue site; wherein said steps of directing said heat energy or said cooling energy for said first time period and said second time period destroy said tissue site alone or in combination.
