US 12,527,624 B2 · Antenna systems and methods of use

Abstract

An antenna system for tissue ablation includes an energy transmission member, a conductive hollow coil member coupled to the energy transmission member, and a fluid cooling system coupled to the conductive hollow coil member for providing a flow of cooling fluid through a member lumen of the conductive hollow coil member for cooling the conductive hollow coil member. In some examples, at least one of the antenna body, a choke member, and a hybrid choke member includes the conductive hollow coil member. In some examples, the hybrid choke member includes a choke portion wound around a portion of the energy transmission member, an antenna body portion wound around a portion of the energy transmission member, and an insulator portion extending between the choke portion and the antenna body portion. In some examples, the antenna system includes a sheath extending over the energy transmission member and the conductive hollow coil member.

Dependent claims

An antenna system for tissue ablation, the antenna system comprising:

an energy transmission member comprising an inner conductor, an outer conductor, and a dielectric layer between the inner and outer conductors;
a conductive hollow coil member including a helical member lumen within a length of the conductive hollow coil member;
and
a non-helical supply conduit providing a cooling fluid from a fluid cooling system to the helical member lumen of the conductive hollow coil member, the non-helical supply conduit being disposed radially outward from and secured to an outer surface of the outer conductor to transfer energy between the non-helical supply conduit and the outer conductor, the non-helical supply conduit being secured to the outer surface of the outer conductor along a length of the non-helical supply conduit between a proximal end of the conductive hollow coil member to a proximal end of the outer conductor.
