摘要：

Spherical biodegradable particles have improved flexibility, cause less aggregation among particles, and have improved particle shape-recovering ability after passing through a catheter or the like. The biodegradable particles include a synthetic polymer chemically cross-linked to a polyvalent carboxylic acid, the biodegradable particles having a water content of 20 to 90% in a water-saturated state.
