Abstract: A brachytherapy device may include an expandable outer cage, an expandable inner cage positioned within the outer cage and configured to receive radioactive material at its perimeter, and a movable actuator configured to cause the outer and inner cages to expand simultaneously in response to movement of the actuator between certain positions while maintaining a substantially constant separation distance between the outer and inner cages.

Abstract: A brachytherapy device may include a plurality of rods, each configured to move between a straightened position and a bowed position, the plurality of rods configured to collectively form a shaft while each rod is in the straightened position and to collectively form at least one cage while at least some of the rods are in the bowed position, at least some of the rods having lumens that are configured to receive and hold radioactive material. A brachytherapy device may further include a rotatable mechanism configured to cause at least some of the plurality of rods to move between the straightened position and the bowed position upon rotation of the rotatable mechanism.

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.
