Abstract
An antenna system for tissue ablation includes 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 defines an outermost portion of the choke member. The choke body has an axial length and the choke connector extends along a majority of the length of the choke body and contacts the choke body along the majority of the length. The choke connector is in direct contact with a fluid from the fluid source. The choke connector is disposed between the choke body and the energy transmission member. The choke connector forms a delivery path for the fluid between the choke body and the energy transmission member. The choke connector and the choke body are a continuous wire mesh.
