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.
