This stent delivery apparatus is provided with: a guide catheter； a pusher catheter in which the guide catheter is inserted； a stent into which the guide catheter is inserted, whereby the stent is disposed further toward the distal side than the tip of the pusher catheter； and a string-like connecting member having a loop shape, the connecting member releasably connecting the stent and the pusher catheter. The pusher catheter has a first communicating hole in a tip part thereof. The stent has a tip opening, a base-end opening, a stent lumen, and a second communicating hole. The stent is arranged so that the base-end opening thereof is positioned on the pusher catheter side. The connecting member has a first end part which passes through the first communicating hole and is supported by the pusher catheter in a state in which the stent and the pusher catheter are connected, an intermediate part which is continuous with the first end part and which extends through the second communicating hole to between the stent and the pusher catheter, and a second end part which is continuous with the intermediate part and which extends to the periphery of a portion of the guide catheter that is positioned between the stent and the pusher catheter.L'invention concerne un appareil de pose d'endoprothèse vasculaire qui est pourvu de : un cathéter de guidage ； un cathéter de poussée dans lequel le cathéter de guidage est inséré ； une endoprothèse vasculaire dans laquelle le cathéter de guidage est inséré, l'endoprothèse étant disposée plus avant vers le côté distal que la pointe du cathéter de poussée ； et un élément de liaison de type chaîne en forme de boucle, l'élément de liaison reliant de manière libérable l'endoprothèse et le cathéter de poussée. Le cathéter de poussée a un premier trou de communication dans une partie de sa pointe. L'endoprothèse a une ouverture de pointe, une ouverture d'extrémité de base, une lumière d'endoprothèse et un second trou de communication. L'endopr
