Abstract
A method for inserting an intra-aortic balloon device into a patient without using an insertion sheath is provided. Additionally, a hemostasis sheath is described for use with the insertion method. The hemostasis sheath may be incorporated onto the balloon catheter during manufacture before attachment of the intra-aortic balloon bladder. The hemostasis sheath is tapered from a smaller outside diameter at the point closest to the balloon bladder gradually increasing in diameter towards a large outside diameter at the end opposite the balloon bladder. The hemostasis sheath may also have an extended tip of constant outside diameter at its proximal end to facilitate insertion through the skin. If bleeding occurs after insertion of the intra-aortic balloon according to the invention, the hemostasis sheath is slid into the insertion site to stop the bleeding.
