ELECTRODE ABLATION BALLOON CATHETER

摘要

Methods, systems, and devices for providing treatment to a tissue in body lumens are described. The system may include a support shaft, an expansion member coupled with a distal portion of the support shaft, and an ablation structure wrapped around the expansion member less than a circumference of the expansion member configured to engage the body lumens with varying sizes. The ablation structure may include multiple separately wired or separately controlled longitudinal electrodes, longitudinal electrode zones, or both, such that each longitudinal electrode or longitudinal electrode zone may be selectively enabled or selectively disabled. The expansion member may include a single highly-compliant balloon, a single non-compliant balloon, multiple non-compliant balloons, or a multi-chambered non-compliant balloon.

1. An ablation device for treatment of tissue in body lumens with varying sizes comprising:
a support shaft; an expansion member coupled with a distal portion of the support shaft; an ablation structure comprising a plurality of longitudinal electrode regions, wherein: the ablation structure is wrapped around the expansion member less than a circumference of the expansion member; and the ablation structure and the expansion member are configured to engage at least a portion of the body lumens with the varying sizes.
