1. A method of treating tissue using microwave, comprising:
gaining access to the body using a radiation applicator, the applicator comprising:
a sharp end to pierce through tissue, the applicator comprising an outer conductor having a proximal end and a distal end;an inner conductor having a proximal end and a distal end;a first dielectric body having a proximal end and a distal end, the first dielectric body is comprised of a first dielectric material having a first dielectric constant, the proximal end of the first dielectric body extends coaxially within the outer conductor;a second dielectric, body having a proximal end and a distal end, the second dielectric body is comprised of a second dielectric material having a second dielectric constant, the second dielectric body has a sharp end capable of piecing through tissue, the second dielectric body having a cavity;a tuning reflector having a proximal end and a distal end, the distal most end and the proximal most end of the tuning reflector are both inside the cavity of the second dielectric body, the tuning reflector is comprised of a third dielectric material having a third dielectric constant;the first dielectric constant, the second dielectric constant, and the third dielectric constant are different; andapplying microwave energy to the affected tissue. |
