In this investigation we used self-expandable metallic stent with 6 bends made by 0.018 inch wire in order to insert the stent percutaneousely. We got a results of expatisile force of 40 gram weight per cm as a preliminary investigation.By using a blood vessel model of vinyl tube, circulating liot water at 65 centigrade in it we got a result of welding strength of 65 gram under the condition of 50 gram compression force for 10 mitixttes.After doing the fundamental experiment mentioned above we can heart up the metallic stent buried 4 cm depth front the atiger surface by external radiofrequency energy. By this experiment previously tearing aorta of dog into media and adverititia welded sufficiently. The welding strength showed 23 grain weight under 10 minutes hearting duration. This experimental results also confirmed Iiistologicaly.

在本研究中，我们使用了自膨胀金属支架，由0.018英寸的金属丝制成6个弯曲，以便经皮插入支架。初步研究得到了40克/厘米重量的拉伸力。在65 ℃低温循环水条件下，在50克压缩力10毫升的条件下，得到65克的焊接强度，在进行了上述基础实验后，可将金属支架埋入4cm深通过外部射频能量将虎的表面切开。本实验通过预先将犬主动脉撕成中膜，使主动脉与主动脉充分吻合。在10分钟加热时间下，焊接强度为23晶粒重量。这一实验结果也证实了免疫学的观点。
