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 a first 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 a first 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.
