A new, percutaneous vena cava filter was developed and tested in 11 dogs. Nitinol wire (0.045 cm diam) spirals were straightened and passed through an 8 French Teflon catheter into the inferior vena cava. The filter resumed its original spiral shape on warming to body temperature and was left in place up to 6 weeks. Long-term patency and capture of injected radiopaque clots were demonstrated. This new filter design may be a simple alternative to currently used implants.
一种新型经皮腔静脉滤器被研制出来并在11只狗身上进行了测试。将镍钛诺丝（直径0.045厘米）螺旋拉直，通过一根8法式聚四氟乙烯导管插入下腔静脉。滤器在升温至体温时恢复其原始螺旋形状，并留置长达6周。结果证明其具有长期通畅性且能捕获注入的不透射线血栓。这种新型滤器设计可能是目前所用植入物的一种简单替代方案。
