评价了由镍钛诺（一种热形状记忆合金）制成的下腔静脉滤器。设计了一系列体外实验以评估其递送后的形状恢复、定向和定位以及其栓子捕获效率。为了进行比较，还测试了Mobin-Uddin和Kimray-Greenfield滤波器。结果表明，镍钛诺滤器易于准确输送，并且在捕获栓子的能力方面上级其他滤器。此外，它没有表现出迁移或显著升高上游静水压力的趋势。
An inferior vena cava filter made from nitinol, a thermal shape memory alloy, was evaluated. A series of in vitro experiments was designed to assess its shape recovery, orientation, and positioning after delivery and its embolus-capturing efficiency. For comparison, the Mobin-Uddin and Kimray-Greenfield filters were also tested. The results indicate that the nitinol filter is easily and accurately delivered and is superior to the other filters in its ability to capture emboli. In addition, it showed no tendency to migrate or to elevate the upstream hydrostatic pressures significantly.
