摘要： The present disclosure provides a brachytherapy apparatus that delivers a low dose, partial breast irradiation treatment for post-lumpectomy patients via introduction of a catheter-like device through a cannula. 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 a seed containment device configured to contain a plurality of low-dose radioactive seeds therein. The seed containment device may be one or more thin-walled tubes. The apparatus is further configured to expand so that at least a portion of the seed containment device is positioned against the remaining tissue and the plurality of radioactive seeds are disposed at the perimeter of the seed containment device. Also described are various clamps for the apparatus, and sleeves for adjusting the size of the device to fit a cavity when the apparatus is in use.

摘要： 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.

摘要： A brachytherapy device for treating tissue within a cavity of a body. The device may include a first set of tubes configured to be inserted into the cavity through an opening at the surface of the body. Each of the tubes may have an external end and an interior channel beginning at the external end that is configured to receive radioactive material. The external ends of the tubes may be bundled together. The tubes may be of a length that causes the external ends to be near the opening in the surface of the body while the tubes are in the cavity. A seal may be configured to prevent fluid that originates from the cavity from entering into the external ends of the tubes while they are near the opening in the surface of the body. The seal may include a gasket that is pressed against the external ends of the tubes. The gasket may have openings that align with channels within the external ends of the tubes.
