DUAL CATHETER ABLATION SYSTEM

摘要

A dual catheter ablation system with an arterial catheter and a venous catheter and at least two magnetic elements, a first magnetic element placed in the arterial catheter and a second magnetic element placed in the venous catheter, where at least one of the arterial catheter or the venous catheter carries an ablating electrode. The first magnetic element has a predefined polarity and the second magnetic element has an opposite polarity with respect to the pre-defined polarity. A protective sheath is provided for enclosing the catheter pair, the first magnetic element and the second magnetic element. The dual catheter ablation system is configured to be placed inside an anatomical region such that a target tissue is in between the first magnetic element and the second magnetic element, bringing the ablating electrode in close proximity to a target tissue.

1. A dual catheter ablation system comprising:
a catheter pair comprising an arterial catheter with a first electrode and a venous catheter with a second electrode, wherein at least one of the first electrode or the second electrode is an ablating electrode; a first magnetic element of predefined polarity placed at a space apart distance adjacent to the first electrode; a second magnetic element of opposite polarity with respect to the pre-defined polarity of the first magnetic element, placed at a space apart distance adjacent to the second electrode; and a protective sheath for enclosing the catheter pair, the first magnetic element and the second magnetic element, wherein the dual catheter ablation system is configured to be placed inside an anatomical region such that a target tissue is in between the first electrode and the second electrode.
