Abstract
Treatment devices with electrode contact surfaces configured for enhancing uniformity of electrical energy distribution are provided. In one embodiment, a treatment device includes a tubular electrode having a wall, a contact surface defined by the wall, and cut shapes at least partially extending through the wall. The tubular electrode is configured to transmit electrical energy to a treatment site within a body lumen via the contact surface, and the individual cut shapes are configured to draw a portion of the electrical energy toward an interior region of the contact surface. A shaft having a distal end portion operably coupled to the tubular electrode can locate the tubular electrode at the treatment site.
