A new device for transcatheter vessel occlusion consists of a stainless-steel spider which can be screwed onto a threaded guide wire. Since the spider can be retrieved after it is extruded from the catheter, accurate placement is possible. The device was tested in the aorta and pulmonary artery of dogs. The spider blocked the movement of steel coils and wool streamers and occluded the vessel. This device is particularly useful for occlusion of large arteriovenous fistulas in the lungs.
一种用于经导管血管闭塞的新装置由一个可拧到带螺纹导丝上的不锈钢蜘蛛状器械组成。由于该蜘蛛状器械从导管中推出后可以回收，因此能够实现精确放置。该装置在犬的主动脉和肺动脉中进行了测试。蜘蛛状器械阻止了钢圈和羊毛条带的移动并闭塞了血管。这种装置对于闭塞肺部的大型动静脉瘘特别有用。
