Bipolar conforming electrode catheter and methods for ablation |
摘要 |
A bipolar conforming electrode catheter has a plurality of flexible filaments or bristles forming a brush electrode for applying therapeutic energy (e.g., RF energy) to target tissue to form spot or continuous linear lesions. Interstitial spaces are defined among the filaments of the brush electrode. The interstitial spaces are adapted to direct conductive or nonconductive fluid, when present, toward the distal ends of the filaments. The brush electrode facilitates electrode-tissue contact in target tissue having flat or contoured surfaces. The flexible filaments may be selectively trimmed to give a desired tip configuration or a desired standoff distance between the tissue and the conductive filaments in the brush electrode. The filaments may be grouped into clusters. The catheter includes a dispersive return electrode for bipolar function.
