Abstract: A catheter for ablating cardiac tissue through irreversible electroporation, the catheter comprises a tubular outer shaft and an electrode assembly extending distally from the distal end of the outer shaft. The electrode assembly defines a distally located central hub portion and a plurality of splines each extending proximally from the central hub portion. The electrode assembly comprises a flexible circuit having a flex circuit hub and a plurality of flex circuit branches integrally formed with and extending proximally from the flex circuit hub, the flexible circuit further including an outwardly-facing ablation electrode including an ablation electrode hub portion located on the flex circuit hub, and a plurality of ablation electrode branches integrally formed with the ablation electrode hub portion, each of the ablation electrode branches extending proximally along a portion of a respective one of the flex circuit branches and terminating in an ablation electrode proximal end.

Abstract: An electrophysiology catheter comprising a tubular shaft, the shaft having a proximal portion, a distal portion having a distal end and a deflection region, the shaft defining a longitudinal axis and including an outer tubular jacket, and articulation member disposed within the jacket in the deflection region, the articulation member comprising a plurality of longitudinally-arranged tubular segments, a plurality of first connecting segments, and a plurality of second connecting segments, wherein adjacent tubular segments are joined by respective ones of the first and second connecting segments, and wherein all of the first and second connecting segments are disposed in a first plane extending through the longitudinal axis. A first reinforcing member and a second reinforcing member extend through the plurality of first and second connecting segments, respectively.
