Claim:
1. A stent delivery system comprising: an inner proximal tube opening at a proximal end thereof; an inner distal tube having a proximal side connected to the inner proximal tube by a connecting member; a stent which is disposed on an outer surface of the inner distal tube while being compressed toward a center axis thereof at the time of insertion into a living body lumen and which can be restored into its pre-compression shape by expanding outward when put indwelling in the living body lumen; and an outer tube which, by being disposed on an outer surface side of the inner distal tube, can contain the stent in its lumen and which, by moving proximally relative to the inner distal tube, can release the stent contained in its inside, wherein a sealing member is provided between the outer tube and the inner proximal tube on a proximal side relative to the stent, and the inner proximal tube is provided, between the sealing member and the stent, with a first opening through which a lumen of the inner proximal tube and the exterior of the inner proximal tube communicate with each other, and wherein said sealing member is fixed to said inner proximal tube on a proximal side relative to said first opening.
