支架是治疗各种原因引起的管腔狭窄的一种方法。圆柱形金属支架由合金丝组成。然而，支架植入后，狭窄可能会因肿瘤或脓肿再次复发。由于胆管位于腹部深处，因此通过手术修复来切除胆管肿瘤或囊肿特别困难。我们提出一种无创性的治疗方法，使用磁激励金属支架热疗肿瘤和脓肿。目前，临床支架的制造不允许加热。本文采用磁分流钢制作实验支架，对支架进行加热，并通过外部磁激励控制支架的热量，以达到热疗的目的。
Stents are one method of treatment for stenosis of lumens organ from various causes. The cylindrical metallic stents are composed of alloy wire. After stents are implanted, however, the stenosis may recur due to a tumor or abscess again. It is particularly difficult to remove tumors or abscesses of the bile duct by surgical repair, because the duct is in a deep portion of the abdomen. We propose a noninvasive remedying method for tumors and abscesses by using thermotherapy with magnetically excited metallic stents. Currently, clinical stents are not manufactured to allow for heating. In this paper, we made experimental stents by magnetic shunt steel to heat the stents and control the heat of stents by external magnetic excitation for thermotherapeutic applications.
