摘要： A guide catheter having a tubular body with a wire-braided Teflon core and a polyurethane jacket. The distal end of the jacket is removed from the core, and a soft polyurethane tip is applied to the core over the region where the jacket has been removed. The tip overlaps the core for approximately two millimeters and extends distally approximately two millimeters beyond the distal end of the core. The tip may be applied to the core as a separate tube bonded to it or be built up on the core by repeatedly dipping the top in a polyurethane slurry, or be molded onto the distal end of the core.
