CRESCENT CHANNEL DYE FLOW ENABLED GUIDE CATHETERS

摘要

An intravascular catheter (100) is disclosed that includes an elongated shaft (610) defined by a wall including at least one port (112) extending through the wall into a lumen (105). At least one channel (210) may be defined between layers of polymer making up the catheter shaft. The channel extends along at least a portion of the shaft and is in fluid communication with the port. Outer and inner diameters of the catheter may be substantially constant along the length of the catheter.
