A stent delivery system includes a tubular stent which is retained in a body cavity of a living body; a pusher tube, whose distal end contacts with a proximal end of the stent, which pushes and moves the stent to a distal end side; a filament which connects the stent with the pusher tube by the prox...

| Summary: | A stent delivery system includes a tubular stent which is retained in a body cavity of a living body; a pusher tube, whose distal end contacts with a proximal end of the stent, which pushes and moves the stent to a distal end side; a filament which connects the stent with the pusher tube by the proximal end side of the filament being engaged with the pusher tube and by the distal end side of the filament stretching to the stent side so as to penetrate the peripheral wall of the stent; an engaging member which is engaged with a distal end portion of the filament penetrating the peripheral wall of the stent, and which keeps the connecting condition between the stent and the pusher tube by the filament; and a pulling member which pulls a distal end side of the filament into a proximal end side of the pusher tube when the engagement between the engaging member and the filament is released and the connection between the stent and the pusher tube is released. |
