ABSTRACT:
An angiographic catheter is described with a valve covering the end-hole on the distal end. The valve will allow the catheter to be passed over a guidewire but will prevent an injected fluid (e.g., a contrast medium) from being discharged from the end hole. The valved-end catheter has side-holes near the distal end that provide for lateral discharge of the fluid thereby preventing the creation of an end-hole jet and the resulting undesirable effects of the jet.
