Abstract
The present disclosure provides a brachytherapy apparatus, system and method that delivers partial breast irradiation treatment for post-lumpectomy patients via introduction of a catheter-like device through a trocar. The apparatus may be introduced post-surgically with local anesthesia under image guidance into the previous excision site and into a cavity by a surgeon. The brachytherapy apparatus includes one or more thin-walled tubes, each of said thin-walled tubes being configured to contain one or more radioactive sources, at least one radiation source configured to deliver a prescribed dose of radiation, a whisk adjuster configured to permit adjustment of each of the one or more thin-walled tubes so that the tubes substantially conform to a size of the body cavity; and an expansion element configured to expand outwardly said one or more thin-walled tubes within the cavity so that the thin-walled tubes substantially conform to a shape and/or size of the body cavity.
