Abstract
An embolic material which prevents flow of a biological fluid by being placed in a body lumen via a catheter, the embolic material comprising a material that swells by contacting the biological fluid. The embolic material includes a long filler that is formed smaller than an inner diameter of the catheter. The filler prevents the flow of the biological fluid by bending when brought into contact with the biological fluid due to the difference in swelling characteristics between a first side portion and a second side portion that extend parallel to one another in a longitudinal direction.
