EMBRYO TRANSFER TOOL AND EMBRYO TRANSFER DEVICE

摘要

An embryo transfer tool has a flexible tube and a hub. The flexible tube has first and second microparticle-containing synthetic resin portions. The first and second microparticle-containing synthetic resin portions are not exposed in outer and inner surfaces of the flexible tube, and are formed by a synthetic resin and a large number of hollow glass beads having a diameter of 0.5 to 200 μm. The hollow glass beads are dispersed in the synthetic resin. The first and second microparticle-containing synthetic resin portions include a large number of boundary surfaces that are formed between the synthetic resin and the hollow glass beads.
