Abstract
High-strength microwave antenna assemblies and methods of use are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. Proximal and distal radiating portions of the antenna assembly are separated by a junction member. A reinforcing member is disposed within the junction member to increase structural rigidity.
Claims20
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 portion, with the inner conductor extending at least partially therein;
- a junction member having a longitudinal thickness, wherein at least a portion of the junction member is disposed between the proximal and distal portions such that the inner conductor extends therethrough;
- a reinforcing member disposed longitudinally at least partially within the junction member and electrically integral with the inner conductor, the reinforcing member having a diameter greater than a diameter of the inner conductor to provide increased stiffness to the junction member;
- a conductor disposed on a distal end of the reinforcing member and configured to contact an inner perimeter of the distal radiating portion to electrically connect the inner conductor to the distal radiating portion;
- and
- a sensor selected from the group consisting of a temperature sensor, a pressure sensor, and a flow sensor.

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 portion and integrally formed and of a single piece with the inner conductor;
- a junction member having a longitudinal thickness, wherein at least a portion of the junction member is disposed between the proximal and distal portions such that the inner conductor extends therethrough, wherein the inner conductor and distal radiating portion reinforce the junction member to provide additional stiffness to the junction member;
- a reinforcing member disposed longitudinally at least partially within the junction member and electrically integral with the inner conductor, the reinforcing member having a diameter greater than a diameter of the inner conductor to provide increased stiffness to the junction member;
- and
- a conductor disposed on a distal end of the reinforcing member and configured to contact an inner perimeter of the distal radiating portion to electrically connect the inner conductor to the distal radiating portion.
