Abstract: Systems and methods for electroporation catheters are disclosed herein. An electroporation catheter includes a shaft, and a plurality of splines forming a basket around a distal portion of the shaft, each spline extending between a proximal end that is coupled to the shaft and a distal end that is coupled to the shaft, wherein each spline of the plurality of splines comprises at least one energizable electrode. The electroporation catheter further includes a balloon positioned within the basket formed by the plurality of splines, the balloon selectively inflatable to facilitate securing a position of the plurality of splines.
