Abstract

Provided are: a penetration catheter that can effectively support a device to be inserted inside and can improve operability of the supported device while having high penetrability into a lesion of a vein; a treatment method; a guide wire; and a catheter system. A penetration catheter 40 used for penetrating a lesion of a vein includes a second tube body 41 that has an outer diameter constant portion 45 having a constant outer diameter in a major axis direction, an outer tapered portion 46 having an outer diameter tapered from a distal end of the outer diameter constant portion 45 in a distal end direction, an inner diameter constant portion 47 having a constant inner diameter in the major axis direction, and an inner tapered portion 48 having an inner diameter tapered from a distal end of the inner diameter constant portion 47 in the distal end direction, in which an outer diameter of the outer diameter constant portion 45 is 2.7 ± 0.1 mm, an inner diameter of the inner diameter constant portion 47 is 1.6 ± 0.1 mm, an outer diameter of a most distal end of the tube body is 1.7 ± 0.1 mm, and an inner diameter of a most distal end of the second tube body 41 is 1.45 ± 0.1 mm.
