Abstract: An inflatable blood perfusion and filter balloon for preventing ischaemia is provided. The balloon comprises: a distinctly shaped inflatable chamber with a plurality of wall portions that form a plurality of lumens when inflated, and the lumens cooperatively defining a plurality of outwardly open channels each extending externally lengthwise between the two ends of the inflated balloon for passage of blood, the lumens are formed integrally between the wall portions of the inflated balloon, and the lumens being fitted with a filter which blocks the debris from moving towards the distal vascular bed.

Abstract: An intravascular cutting device to open hard vascular lesions particularly to act directly on the plaques or calcified blood vessels and eliminating balloon configuration. The device is for use in interventional cardiology in an artery which is configured with plurality of blades (14) mounted in winged openable/closeable configuration forming around a shaft (7). The device is openable/ closeable with a handle (15). These blades (14) can be pulled selectively radially outwardly like an umbrella. The cutting arms (10) are conventional.
