  • Patent number: 11389620
    Abstract: A catheter (100) includes a resin-made distal tip (80) linked to a distal end of a catheter body (10), and the distal tip (80) has a distal lumen (81) having an open distal end. The distal lumen (81) communicates with a lumen (31). The catheter (100) is an inactive type microcatheter in which an outer diameter of the distal end of the catheter body (10) is 0.6 mm or smaller and a maximum outer diameter of the distal tip (80) is 0.6 mm or smaller. A dimension of a marker (70) in an axial direction of the catheter body (10) is smaller than the maximum outer diameter of the distal tip (80), and the length of the distal tip (80) in the axial direction of the distal tip (80) is 3 times to 18 times the maximum outer diameter of the distal tip (80).
