ELECTROPORATION ABLATION APPARATUS, SYSTEM, AND METHOD

摘要

An ablation system including a first probe extending through a first longitudinal lumen from a proximal end to beyond a distal end of a flexible shaft, a first electrode coupled to a distal end of the first probe, and a first conductor electrically coupled to the first electrode. The ablation system further includes a second probe extending through a second longitudinal lumen from the proximal end to beyond the distal end of the flexible shaft, a second electrode coupled to a distal end of the second probe, and a second conductor electrically coupled to the second electrode. The first and second probes are rotatable and translatable within the first and second longitudinal lumens respectively. Furthermore, the first electrode and the second electrode are rotatably and translatably positionable with respect to one another, via the first probe and the second probe respectively, to define a region therebetween.

1. An ablation apparatus, comprising:
an elongate shaft comprising a proximal end and a distal end, wherein the elongate shaft defines:
a first lumen extending between the proximal end and the distal end; anda second lumen extending between the proximal end and the distal end; a first probe extending through the first lumen from the proximal end to beyond the distal end of the elongate shaft, wherein the first probe is rotatable and translatable within the first lumen; a first electrode attached to a distal end of the first probe, wherein a first conductor is electrically coupled to the first electrode; a second probe extending through the second lumen from the proximal end to beyond the distal end of the elongate shaft, wherein the second probe is rotatable and translatable within the second lumen; a second electrode attached to a distal end of the second probe, wherein a second conductor is electrically coupled to the second electrode; and wherein the first electrode and the second electrode are rotatably and translatably positionable with respect to one another, via the first probe and the second probe respectively, to define a region therebetween.
