Abstract
This is a bloodflow-directable infusion catheter which may be used in cardiovascular and endovascular procedures to deliver diagnostic, therapeutic, or vaso-occlusive agents to a target site accessible through the vasculature. The device is a flow-directed infusion catheter having a variety of sections of different flexibilities with tapered junctions between those sections. Additionally, at least some of the inventive catheter's sections have radio-opaque markers at or near the distal end of the individual sections. The more distal section or sections of the inventive catheter may be severed from the catheter body by the physician user so that the remaining catheter has a suitable diameter for the chosen task and the resulting severed end has a radio-opaque marker showing the catheter's distalmost end.
