Development of block copolyether‐urethane intra‐aortic balloons and other medical devices

Abstract The development of materials and technology suitable for the fabrication of intra‐aortic balloons (IABs) is described; a brief discussion of materials and a fabrication process for flexible ventricular assist devices (heart massage cups) is also given. A series of block copolyether‐urethanes was developed, the mechanical properties of which can be varied over a wide range. One member of the series was “tailored” specifically for …
