Date Jan. 14, 1988.A dilation catheter is provided with an inflatable balloon which can be made to advance into a narrowed coronary artery along a guide wire placed by a guide catheter. An inflating tubular body is provided for expanding the balloon, which consists of a hose-like outer skin to which is connected, at the axially oriented edges, an inner skin also having a hose-like shape. Between the inner skin and the outer skin is a balloon interior space which surrounds an open central lumen extending axially through the balloon and ensures during dilatation a constant flow of blood into the coronary artery.
