MICROSPHERES CONTAINING RADIOACTIVE ISOTOPES AND OTHER MARKERS, AND ASSOCIATED METHODS

Multiphase microspheres for radioembolization include two-phase microspheres and three-phase microspheres prepared by a microfluidic process. The multiphase microspheres include a primary phase and afirst secondary phase surrounded by the primary phase. The primary phase includes a first resin. The...

Beschreibung
Zusammenfassung:	Multiphase microspheres for radioembolization include two-phase microspheres and three-phase microspheres prepared by a microfluidic process. The multiphase microspheres include a primary phase and afirst secondary phase surrounded by the primary phase. The primary phase includes a first resin. The first secondary phase includes a second resin and at least one of a radioactive isotope or a compound including at least one radioactive element. Three-phase microspheres additionally include a second secondary phase discrete from the first secondary phase and also surrounded by the primary phase.The second secondary phase may be a gas such as air. The microspheres may be formed by a microfluidic process. 用于放射性栓塞的多相微球包括通过微流体方法制备的两相微球和三相微球。多相微球包括主要相和被主要相围绕的第一次要相。主要相包括第一树脂。第一次要相包括第二树脂、和放射性同位素或包括至少一种放射性元素的化合物中至少一种。三相微球额外包括与第一次要相分离并也被主要相围绕的第二次要相。第二次要相可为气体例如空气。可由微流体方法形成微球。
