TREATMENT DEVICE WITH ELECTRODE CONTACT SURFACE CONFIGURED FOR ENHANCING UNIFORMITY OF ELECTRICAL ENERGY DISTRIBUTION AND ASSOCIATED DEVICES AND METHODS

摘要

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.
