摘要： Methods and apparatus are described for irradiating living tissue via a cavity or lumen, using an inflatable balloon applicator. In a preferred embodiment the applicator balloon has a balloon skin with x-ray contrast material in relatively low concentration, so that an outline of the balloon will appear sharply when imaged externally. In another preferred embodiment the balloon catheter has a drain for withdrawing liquids from the cavity, which may include channels or texture on the exterior of the balloon. Methods are described for using a switchable miniature x-ray tube, variable as to voltage and current, to achieve accuracy in an isodose profile.

摘要： Methods and applicator apparatus are disclosed for brachytherapy treatment of tissue surrounding a cavity in a patient, particularly a resection cavity. In treatment regimes requiring recovery time between successive radiation treatments, applicators of the invention are retained under the skin, with the skin allowed to at least partially heal, and are re-accessed later for one or more subsequent treatments. To reduce patient discomfort an anesthetic agent can be infused through the applicator to patient tissue, for insertion, balloon inflation or removal of the applicator.
摘要翻译： 公开了用于近距离放射治疗患者，特别是切除腔中的腔周围的组织的方法和施用装置。 在需要在连续辐射治疗之间恢复时间的治疗方案中，本发明的施用器保留在皮肤下，允许皮肤至少部分愈合，并且稍后重新进行一次或多次随后的治疗。 为了减少患者的不适，麻醉剂可以通过施用器输注到患者组织，用于插入，球囊充气或去除涂抹器。

摘要： A customized gynecological brachytherapy applicator is formed by placing a molded balloon, which is secured to a handle, into a vaginal cavity and then filling the mold balloon with a settable liquid material. The material may be an expanding foam or any other form of curable material that becomes solid, rigid or pliable, when set by chemical action, temperature change, oxidation, a curing means such as a light, or other curing regime. The mold balloon can be elastic or inelastic, depending on the degree to which the applicator is to conform its external surfaces to the vaginal contours. One or more lumina are provided in the set filler material to receive a radiation source, with additional lumina optionally provided for purposes such as drainage or administration of therapeutic agents. The applicator may be withdrawn and reinserted into the vagina during treatment, and selected tissues adjacent to the applicator are irradiated in accordance with a radiation prescription.
