摘要：An intra-aortic balloon adapted to be percutaneously inserted into a bloodvessel in which the balloon and its support member are twisted as the balloon envelopeis wrapped around its support member before insertion into the vessel to reduce thediameter of the balloon envelope. The support member is twisted as the balloon iswrapped, thereby storing energy which, urges the unwrapping of the balloon in thevessel. In one embodiment, the support member is hollow to permit a guide wire to passthere-through so that placement of the balloon within the human body may be donewith greater precision and the hollow support member permits the injection of aradiopaque fluid so that the balloon can be viewed within the vessel, thereby assisting inthe placement of the balloon. In another embodiment, a solid energy storage supportmember with a highly flexible distal portion provides an intra-aortic balloon of enhancedpliability.
