The technology of balloon catheters in interventional angiography.

Balloon catheters with expansion capabilities from 1 mm to 6 cm have been developed. They feature torque control and can be selectively positioned within vessels as easily as the ordinary diagnostic angiographic catheters. The balloons can be utilized for hemorrhage control, conventional embolectomy, operative angiography, vena cava occlusion, and purposeful vascular thrombosis or dearterialization. In the event of unsuccessful control, the balloon can be readily deflated and removed within minutes.
