Abstract
A system for use in tumor ablation. The tumor ablation system includes a microwave antenna which has a channel along the length thereof. There are two ports proximate the proximal end of the microwave antenna. The first port is an energy port configured to connect the antenna to an energy source. The second port is a fluid port configured to connect the channel to a fluid delivery mechanism. The system also includes an inflatable balloon configured to be attached to a distal end of the antenna. The channel permits fluid access from the fluid port to an interior of the balloon for inflation thereof.
Claims20
A method of tumor ablation, the method comprising:
- making an incision in skin of a patient;
- creating an opening in a bone having a tumor;
- inserting a portion of a microwave antenna system into the opening in the bone, the antenna system including a microwave antenna having a proximal end, a distal end opposite the proximal end, a length between the proximal end and the distal end, a first conductor terminating at an end at the distal end of the antenna, a second conductor terminating at an end positioned between the proximal end and the distal end of the antenna, and a first channel and a second channel extending along at least a portion of the length of the antenna along portions of the first conductor and the second conductor, an energy port proximate the proximal end to connect the antenna to an energy source, a fluid port proximate the proximal end to connect the first channel and the second channel to a fluid delivery mechanism, an inflatable balloon attached to the antenna adjacent the end of the second conductor and having an interior fluidly communicating with the first channel and the second channel, and a flexible member connecting the first conductor to an end portion of the balloon in the interior thereof;
- positioning at least the balloon adjacent the tumor;
- introducing a fluid through the fluid port and through the first channel and the second channel to inflate the balloon causing the balloon to apply pressure to the tumor;
- applying energy through the energy port to one of the first conductor and the second conductor to heat the fluid in the balloon and heat the tumor;
- constraining movement of the end portion of the balloon relative to the first conductor using the flexible member;
- and
- removing the microwave antenna system from the patient.

- positioning at least the balloon adjacent the tumor;
- introducing a fluid through the fluid port and through the at least one channel to inflate the balloon causing the balloon to apply pressure to the tumor and create a cavity in the bone;
- applying energy through the energy port to one of the first conductor and the second conductor to heat the fluid in the balloon and heat the tumor;
- constraining movement of the end portion of the balloon relative to the first conductor using the flexible member;
- and
- removing the microwave antenna system from the patient.
