Abstract:
1. A microwave antenna assembly for applying microwave energy therapy, comprising: a proximal radiating portion having an inner conductor and an outer conductor, each extending therethrough, the inner conductor disposed within the outer conductor; a distal radiating portion disposed distally of the proximal radiating portion, with the inner conductor extending at least partially therein; an electrical choke portion disposed proximally of the distal radiating portion and at least partially over the proximal radiating portion, the electrical choke portion having a conductive layer and at least one dielectric layer disposed between the conductive layer and the outer conductor of the proximal radiating portion; and a junction member having a longitudinal thickness and having at least a portion of which is disposed between the proximal and distal radiating portions such that the inner conductor extends therethrough, wherein the distal radiating portion and proximal portion apply a compressive force on at least a portion of the junction member.
