摘要：
Catheter and method of manufacturing such catheter. The catheter includes an elongate shaft having an interior lumen extending therethrough. The interior surface of the lumen is geometrically configured to reduce friction and increase catheter performance. Additionally, the geometrically configured inside surface allows dye or blood to perfuse past the distal end of the catheter when engaged in the coronary artery. The catheter may also include a geometrically configured outer surface at its distal end having perfusion channels to allow blood to perfuse past the distal end of the catheter during catheter engagement.
