Abstract
A vascular catheter comprises an elongated, flexible tubular catheter body. In accordance with this invention, a relatively rigid tunnel member is carried laterally on the catheter body outside of the catheter body. The tunnel member defines an open, non-collapsible, longitudinal passageway for blood flow outside of the catheter body when the vascular catheter is inserted in a blood vessel of a patient.
