ABSTRACT:
In a blood perfusion system comprising a dilation catheter defining a lumen and including a dilating member at the leading end, and a sheath defining a bore through which the dilation catheter is inserted to define a blood intake gap between the outer surface of the dilation catheter and the sheath bore and including a transverse bore branched from the sheath bore, a tube is connected at one end to the transverse bore and at another end to the lumen of the dilation catheter at a trailing end. When the sheath having the dilation catheter inserted therein is set in a blood vessel, a pump in the tube operates to take blood into the blood intake gap in the sheath, pass through the tube and the dilation catheter lumen, and feed back to the periphery of a lesion through the open leading end of the dilation catheter. The patient's own fresh blood can be injected without the need for a further cutdown or puncture for blood intake.
