DILATOR AND CATHETER ASSEMBLY

DILATOR AND CATHETER ASSEMBLY

A dilator (30) insertable into a catheter (20) includes a tubular shaft part (40), and a tubular flexible part (50) located on a distal end side of the shaft part (40) and formed of a resin more flexible than the shaft part (40), and includes, in the shaft part (40) and/or the flexible part (50), a...

description A dilator (30) insertable into a catheter (20) includes a tubular shaft part (40), and a tubular flexible part (50) located on a distal end side of the shaft part (40) and formed of a resin more flexible than the shaft part (40), and includes, in the shaft part (40) and/or the flexible part (50), a physical property inclined part (42) in which rigidity gradually decreases from a proximal end side toward a distal end side. The catheter assembly is capable of achieving both stable catheter insertability into a blood vessel and reduction in risk of blood vessel perforation.
