- 摘要：
PROBLEM TO BE SOLVED: To provide a biodegradable spherical particle which does not cause the aggregation clogging in a pipe with a fine diameter or blood vessel having a smaller inner diameter than the particle size of an instrument such as a catheter, needle, syringe and the like used mainly for pharmaceutical and medical use and which can restore them into the original profile after passing the pipe.
SOLUTION: The spherical particle is characterized by comprising a water-soluble polymer and a biodegradable polymer or a water-insoluble polymer obtained by binding the water-soluble polymer and the biodegradable polymer wherein the weight content ratio of the water-soluble polymer versus biodegradable polymer is 0.60-0.70.
