1. A medical device comprising:
a body having a plurality of struts defining a plurality of cells and forming a mesh, the body being expandable from a first configuration to a second configuration, the body having a tubular working length portion when the body is expanded to the second configuration, and a proximally tapering non-working length portion disposed proximal of the working length portion, wherein the plurality of struts comprise an electrically conductive material and are interconnected such that the plurality of struts are in electrical communication with one another;
a plurality of electrodes, each comprising a radiopaque marker mounted onto and circumferentially surrounding a respective elongated projection that is connected to and extends alongside one of the plurality of struts of the body within the working length portion; and
a plurality of conductive leads extending alongside the body, wherein each of the plurality of conductive leads is electrically coupled to a respective one of the plurality of electrodes.
