BIODEGRADABLE PARTICLES, VASCULAR OCCLUSION MATERIAL, AND METHOD FOR PRODUCING BIODEGRADABLE PARTICLES |
摘要 |
The objective of the present invention is to provide: spherical biodegradable particles having an ameliorated insufficiency in flexibility, having resistance to the occurrence of particle agglomeration, and having an increased particle shape restoring force after passing through a catheter or the like; and a method for producing the biodegradable particles. The present invention provides biodegradable particles formed from the chemical crosslinking of a synthetic polymer and a polyvalent carboxylic acid, and having a moisture content in a water saturated state of 20-90%. |
