The authors modified Gianturco expandable metallic stents to make them relocatable. Two tandem designs were made. The first design had long struts and, thus, more evenly distributed expansive force; the second had short struts and more flexibility and was better suited for use in curved strictures. Both designs (two to four in tandem, 0.012-, 0.014-, and 0.018-inch wire) were tested successfully in vitro, and both designs (two to four in tandem, 0.012-inch wire) were successfully placed, retrieved, and relocated in the inferior vena cava of five dogs.
作者对Gianturco可扩张金属支架进行了改良，使其可重新定位。制作了两种串联设计。第一种设计的支杆较长，因此扩张力分布更均匀；第二种设计的支杆较短，柔韧性更强，更适合用于弯曲狭窄处。两种设计（串联两至四个，使用0.012英寸、0.014英寸和0.018英寸的金属丝）均在体外成功测试，且两种设计（串联两至四个，使用0.012英寸的金属丝）均成功植入、取出并重新定位在五只犬的下腔静脉中。
