摘要： 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.

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.

摘要： A system and method of treating an affected region of diseased tissue in a patient is described. A plurality of first radioactive seeds and a plurality of second radioactive seeds are implanted in the affected region. The first radioactive seeds each have one or more X-ray detectable markers providing a first X-ray detectable signature and the second radioactive seeds have one or more X-ray detectable markers providing a second X-ray detectable signature. An X-ray image of the affected region, including the first and second radioactive seeds implanted therein, provides representations of the first and second X-ray signatures which are visibly distinguishable. Representations of the first X-ray signature may then be associated with implanted seeds having a radioisotope source or dosage of the first radioactive seeds and representations of the second X-ray signature may then be associated with implanted seeds having a radioisotope source or dosage of the second radioactive seeds.

摘要： The present invention relates to an apparatus and method for loading radioactive brachytherapy seeds into a seed cartridge for use with an applicator. Embodiments of the apparatus according to the present invention may include a number of contact points of a size and shape designed to conform to the main body of a brachytherapy seed. The apparatus may hold the seeds until the seeds are placed within a channel of the seed cartridge, at which point the seeds may be released from the contact sites by the application of a force to the seeds or by some other mechanism. The apparatus may be made from a flexible material so that the seeds may be released by the application of a tension force. According to embodiments of the method of loading the seed cartridge, seeds in the loader may be positioned in relation to the body of the loading apparatus and the ends of the seeds may be aligned with the channel of the seed cartridge. A seed may be placed in the channel so that a gripping portion of the loading device protrudes from an access portion of the channel. The apparatus may include gripping features so that the loading apparatus can be held firmly during the loading process.
