Balloon catheter for intra-aortic balloon pump apparatus

1. Field of the Invention A balloon catheter for intra-aortic balloon pump which measures accurate blood pressure at the predetermined position of balloon introduced percutaneously and ensures the second lumen when catheter is in use. The balloon catheter comprised of a Y-shaped connector having gas supply port and an electric circuit, a hollow catheter tube one of which end is connected to the Y-shaped connector, a balloon one of which end is connected to the other end of the catheter tube, a hollow central tube one end of which is connected to one end of the balloon and extended through inside of the catheter tube and the balloon. The balloon catheter includes a pressure detecting element which enables to measure the pressure on the surface of a top end chip connecting the balloon and the central tube. The balloon catheter provided with a detachable connecting device transmitting output signal from the pressure detecting element to an external control device.
