Patent ID: 7128739

Claim:
A method for delivering microwave energy therapy comprising: providing a first microwave antenna comprising a proximal portion having an inner conductor and an outer conductor, each extending therethrough, the inner conductor disposed within the outer conductor; and a distal portion attached to the proximal portion such that the inner conductor extends at least partially therein, wherein each of the proximal and distal portions are configured to mate together such that the proximal and distal portions are fixedly positioned relative to one another by a mechanically engaging joint coupling the distal portion to the proximal portion; positioning the first microwave antenna in a first position in or near a region of tissue to be treated; positioning at least a second microwave antenna in a second position in or near the region of tissue to be treated; applying microwave energy to the first and second microwave antennas such that a combined ablation region is created about the antennas for treating the region of tissue.
