1. An electrosurgical device suitable for puncturing a tissue, the electrosurgical device comprising:
an electrically conductive elongate member comprising, a lumen extending longitudinally therethrough, a distal region having an integral puncturing distal end including a distal tip forming an electrode emitting radiofrequency energy for radiofrequency perforation, and a proximal region having a proximal end, wherein the electrically conductive elongate member is a metal tube;
a hub coupled to the electrically conductive elongate member, the hub having a hub conductive member in electrical communication with the electrically conductive elongate member, and a hub fluid flow path extending from a hub fluid connector to the lumen of the electrically conductive elongate member, the hub fluid connector operable to place the hub fluid flow path in fluid communication with a fluid source; and
a hub port for receiving an electrical connector operable to place the hub conductive member in electrical communication to an energy source,
whereby an electrical conduction pathway between the energy source and the electrically conductive elongate member includes the hub conductive member, and whereby the hub fluid flow path provides a fluid pathway between the fluid source and the distal region of the electrically conductive elongate member.
