A segmented polyether urethane was used as the blood contacting surface in a series of 10 heart assist devices implanted in calves for periods up to 35 weeks. At termination, each was examined to correlate blood compatibility and device performance with surface properties, chemical purity, physical stability and affinity for lipid absorption.
一种分段聚醚聚氨酯被用作一系列10个心脏辅助装置的血液接触表面，这些装置植入小牛体内长达35周。在实验结束时，对每个装置进行检查，以将血液相容性和装置性能与表面性质、化学纯度、物理稳定性以及脂质吸收亲和力相关联。
