APPARATUS AND METHOD FOR ABLATION OF SOFT TISSUE SURROUNDING A BREAST CAVITY FOLLOWING LUMPECTOMY

摘要

Methods and systems for delivering a cryogenic fluid to an inner surface of a surgical excision cavity, such as following breast tumor removal, are described. A single or dual balloon configuration can be utilized to deliver a cryogenic fluid to necrose tissue surrounding the tumor cavity in order to reduce the risk of recurrence of the cancer. The balloon can be optimally configured for maximum contact with the breast tumor bed.
