Abstract

A method for embolization treatment was developed in which microspheres with novel properties are administered in a mammal. The microspheres are made using a novel process that results in microspheres with new combined properties of high density, low fracture, high swell capacity, rapid swell, and deformability following swell. These microspheres form occlusions with high durability, withstanding over 100 mm Hg (13.3 kPa) of pressure.
