摘要：
Catheters adapted for use in small body vessels are described. A catheter includes an elongate shaft having a main body that defines first and second lumens. An inner tubular member is disposed in the second lumen and is formed of a material that has a stiffness that is greater than a stiffness of the material forming the main body and that has an elastic modulus greater than or equal to about 400 MPa.
