Abstract

An intravascular guide catheter includes a main shaft member, a bond member, an intermediate shaft member and a terminal shaft member. The main shaft has a proximal end and a mating distal end. The bond ring includes a mating proximal end, which is joined to the mating distal end of the main shaft member, and a mating distal end. The intermediate shaft member includes a mating proximal end, which is joined to the mating distal end of the bond member, and a mating distal end. The terminal shaft member includes a mating proximal end, which is joined to the mating distal end of the intermediate member, and a distal end. The main and intermediate shaft members have wire braiding reinforcing layers. The material of the intermediate shaft member has a greater hardness than the material of the terminal shaft member and a lower hardness than the material of the main shaft member.
