ABSTRACT:
A stent delivery system1for supplying a stent to a body cavity which includes an endoscope6that has an insertion portion5with a curvature portion3disposed at the distal end thereof, a sheath7that is disposed with the insertion portion5inserted in the inside thereof and a stent2placed on the outer surface of the distal end side thereof; and a regulating portion8that regulates the relative movement of the stent2to the proximal end side of the sheath7, with the sheath7formed of a length that allows the distal end of the insertion portion5that is inserted in the sheath7to protrude from the distal end of the sheath7. In accordance with the present invention, it is possible to provide a stent delivery system that can place a stent by endoscope observation without the need of excessive diametrical contraction or additional expansion of the stent.
