摘要：
An intra-aortic balloon pump (IABP) is provided that has a series of spiral pleats that function to control the wash of blood associated with an inflation cycle. Additionally, the torsional expansion increases the net efficiency of the IABP relative to a conventional cylindrically shaped balloon. The inflating membrane is textured to promote natural growth of a biologic lining on the surface of the indwelling pump to reduce the need for anticoagulation and the risk of thromboembolic events； promote washing of the surface to minimize stasis and thrombus formation； minimize strain on the IABP； minimize elongation radially and longitudinally to avoid fatigue of the IABP； minimize stretching and stress distribution along a balloon； promote a sweeping effect through the channels in the non-expanded state to wash the surface； or a combination thereof.
