研制了一种新型自定心不锈钢下腔静脉滤器(三叶草滤器)，可通过10-F导管经皮输送。过滤器被装载到血管造影术导管中，作为一组拉直的钢丝，当设备交付时，这些钢丝被机械变形成预定的三叶草形状。该过滤器可以方便有效地部署到模拟的下腔静脉中。比较了新型滤器与Greenfield滤器和鸟巢下腔静脉滤器的体外栓子捕集效率。所有三个过滤器都捕获了所有5x100毫米的可能致命的大栓子。与绿地过滤器相比，三叶草过滤器能捕获更多较小的栓子(5 x 20 mm和3 x 20 mm)，但比鸟巢过滤器捕获的栓子更少。
A new self-centering stainless steel inferior vena cava filter (clover leaf filter) that can be delivered percutaneously through a 10-F catheter has been developed. The filter is loaded into an angiographic catheter as a set of straightened wires that are mechanically deformed into a predetermined clover leaf shape when the device is delivered. The filter can be deployed easily and effectively into the simulated vena cava. Emboli-capturing efficiency of the new filter was compared in vitro to that of the Greenfield and Bird's Nest inferior vena cava filters. All three filters captured all large 5 x 100-mm, potentially fatal emboli. The clover leaf filter captures more of the smaller (5 x 20-mm and 3 x 20-mm) emboli than the Greenfield filter and less than the Bird's Nest filter.
