摘要：The present invention is a catheter device provided with a catheter (2) and asheath (1) through which the catheter passes. The catheter has an insertion guidemember (5) attached to its tip, a balloon (3) provided on the tip side for widening thediameter of a vascular stent (4), and an expansion medium supply path (7) through whichthe expansion medium for expanding the balloon is supplied. The sheath is operated tomove, relative to the catheter, over a span between a position where the sheath coversthe balloon to which the vascular stent is fitted and a position where the vascular stentfitted onto the balloon is at the verge of being outside the sheath. The following areprovided between the sheath and the catheter: a first movement restriction part (35) thatregulates the projection of the tip-side of the sheath from the tip-side of the catheter,and a second movement restriction part (40) that regulates the amount that the tip-sideof the catheter projects outward. By regulating the relative movement position of thesheath with respect to the catheter, excess movement of the sheath is controlled.
