Abstract
A neuromodulation catheter includes an elongate shaft and a neuromodulation element. The shaft includes two or more first cut shapes and two or more second cut shapes along a helical path extending around a longitudinal axis of the shaft. The first cut shapes are configured to at least partially resist deformation in response to longitudinal compression and tension on the shaft and torsion on the shaft in a first circumferential direction. The second cut shapes are configured to at least partially resist deformation in response to longitudinal compression on the shaft and torsion on the shaft in both first and second opposite circumferential directions.
