1. An antenna system for tissue ablation, the antenna system comprising:
an energy transmission member;
an antenna body coupled to the energy transmission member;
a fluid source; and
a choke member comprising an integrally formed choke body and choke connector electrically coupled to the energy transmission member by the choke connector, the choke body defining an outermost portion of the choke member, the choke body having an axial length and the choke connector extending along a majority of the axial length of the choke body and contacting the choke body along the majority of the axial length, the choke connector in direct contact with a fluid from the fluid source, the choke connector disposed between the choke body and the energy transmission member, the choke connector forming a delivery path for the fluid between the choke body and the energy transmission member, wherein the choke connector and the choke body are formed of a continuous wire mesh.
