PERISTALTIC MOTION CONVEYING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for conveying an object without excising a blocked part of a transport path when a lesion not excisable by surgery appears in the esophagus.

SOLUTION: Bidirectional shape memory alloys 101 are attached to a plurality of parts of a stent 100 retained in the transport path, and driven to sequentially change a tube cross-sectional area in a conveying direction to convey the object in one direction.
