Systems and methods for isolating wires in electroporation devices

Abstract

To provide systems and methods for electroporation catheters.SOLUTION: An electroporation catheter includes a shaft, and a variable diameter loop coupled to a distal end of the shaft, the variable diameter loop including a plurality of electrodes. The catheter further includes a plurality of electrical wires connected to the plurality of electrodes and extending through the variable diameter loop and the shaft, the plurality of electrical wires configured to energize the plurality of electrodes, and a multi-lumen arrangement 500 extending through at least a portion of at least one of the shaft and the variable diameter loop. The multi-lumen arrangement includes a first lumen 510 housing a first subset of the plurality of electrical wires, and a second lumen 512 housing a second subset of the plurality of electrical wires.SELECTED DRAWING: Figure 5B
