    摘要： A catheter assembly includes a catheter (30) having a first lumen (34) and a second lumen (41) and an inner needle (12) inserted through and disposed in the first lumen and allowing blood to flow in the proximal direction of the catheter (30) from a needle tip exposed at the distal end of the catheter (30). The gap between an outer peripheral surface of the inner needle (12) and a distal end inner peripheral surface of the first lumen (34) continuous with the distal end of the catheter (30) is narrower than the gap between the outer peripheral surface of the inner needle (12) and a basic inner peripheral surface closer to the proximal end side than the distal end inner peripheral surface.

    摘要： Provided is a balloon catheter comprising: an outer tube 11; an inner tube 12 which is inserted into a lumen 11a of the outer tube 11 and the base-end portion of which is bonded to the outer tube 11; and a core wire 30 which is inserted into the lumen 11a of the outer tube 11 and is extended further toward the leading-end side than the base-end portion of the inner tube 12. In an overlapping range 35 in which the inner tube 12 and the core wire 30 overlap in the axial direction, a wall portion 37 is disposed at an intermediate position in said axial direction. A hole part 41 through which the inner tube 12 is inserted and a hole part 42 through which the core wire 30 is inserted are formed in the wall portion 37. The inner tube 12 is secured to the outer tube 11 via the wall portion 37, and the core wire 30 is not secured to the wall portion 37.
