Abstract:
A diagnostic sheath assembly for facilitating atraumatic navigation of guide catheters along vascular pathways, comprising:an elongated catheter body having a proximal end and a distal end;an elongated shaft disposed in the elongated catheter body and extending from the proximal end to the distal end of the catheter body, the elongated shaft having a proximal end and a distal end;a guide wire lumen extending through the elongated shaft from the proximal end to the distal end for receiving a guide wire;at least one dye-injection lumen extending through the elongated shaft from the proximal end and joining the guide wire lumen at a point near the distal end of the shaft to provide fluid communication between the at least one dye-injection lumen and the guide wire lumen.
