A medical device for lacerating tissue includes an elongate shaft with a distal region and an inflatable balloon secured to the distal region. The balloon has an outer surface and can transition between deflated and inflated configurations. The device features an electrode assembly on the outer surface with multiple electrodes optionally arranged in a grid pattern. The balloon may be constructed of polyimide or polyamide materials, potentially with multiple layers. The electrodes can be individually activated to create various cutting patterns and may be arranged axially or non-parallel to each other. Some embodiments include an insulative surface adhered to the balloon's outer surface with a conductive pattern defining the electrodes. The electrode assembly may be radiopaque and can include monopolar annular electrodes with separate ground electrodes.
