Intravascular catheter with kink resistant tip |
摘要 |
An intravascular catheter comprises a proximal portion and a distal portion. The proximal portion has greater torsional stiffness than the distal portion, while the distal portion has greater dependability than the proximal portion. In accordance with this invention the distal portion carries a helical wire support member embedded therein, the helical support member being essentially free of crossing wires, to provide kink-resistance upon bending to the distal portion.
