摘要： A catheter assembly includes a catheter and a dilator. The catheter has a first curved portion at a front end portion thereof. The dilator includes a protruding portion, a low stiffness portion, and a high stiffness portion. The protruding portion is arranged on a front end portion of the dilator. At least part of the protruding portion protrudes from a front end of the catheter when the dilator is inserted into the catheter. The low stiffness portion is arranged on a rear side of the protruding portion and at a position corresponding to the first curved portion of the catheter, and has a lower flexural stiffness than the protruding portion. The high stiffness portion is arranged on a rear side of the low stiffness portion and has a higher flexural stiffness than the low stiffness portion.

摘要： An object of the present invention is to provide a device used in an operation using a catheter assembly and the catheter assembly having the device, which allows a hole formed in a body surface to have a minimum size and a catheter to be smoothly inserted into the body. An auxiliary dilator includes a body part having a tapered portion tapering toward a front end of the auxiliary dilator. The body part surrounds an extension part of a main dilator with a front end entry portion of the extension part protruding from the tapered portion, and a separation part attached to the body part enabling the body part to be removed from the main dilator.

摘要： A catheter (1) includes catheter shaft (10) with an inner layer (24) and a braid (26) provided on an outer periphery of the inner layer (24) and including first wires (26a) and second wires (26b) that are woven together, and a tip (12) provided on a distal end of the inner layer (24) and a distal end of the braid (26). A residual portion having a sharp shape formed at a distal end of the first wire (26a) when the first wires (26a) are cut is not left untreated, but is formed into a bulging portion (27, 37, 47, 57).
