Abstract
A probe includes a shaft and an applicator head designed to treat irregularly-shaped hollow cavities, such as a cavity in breast tissue created by a lumpectomy procedure. The applicator head has a fixed geometry, and a plurality of electrodes can be advanced from an exterior surface of the applicator head in an omnidirectional pattern. The electrodes are used to deliver radiofrequency current or other energy to ablate the marginal tissue.
Claims42
A probe for ablating tissue surrounding a body cavity, said probe comprising:
- a shaft having a distal end;
- an applicator head having an outer surface which is fixedly configured to occupy a volume of the body cavity;
- a plurality of electrodes disposed within at least the applicator head, wherein said electrodes are reciprocatable between a retracted configuration where distal portions of the electrodes are retracted within the applicator head and an advanced configuration where the distal portions extend beyond the outer surface of the applicator head.
A method for ablating tissue surrounding a body cavity, said method comprising:
- introducing an applicator head into the body cavity, wherein the applicator head has a fixed configuration which substantially occupies a volume of the body cavity;
- advancing a plurality of electrodes from an outer surface of the applicator head to the tissue surrounding the body cavity;
- and
- delivering energy through the electrodes to ablate or cauterize the tissue.
