Current-dependent kinetic inductance of superconducting thin films is studied experimentally. A measurement circuit for the precise measurement of the kinetic inductance is developed for this purpose. The voltage across an inductance made of YBaCuO meander line is measured as a function of applied current. From the nonlinear relationship between the voltage and the current measured in the experiment, dependence of the kinetic inductance on the current is obtained. The experimental results are consistent with the theoretical results predicted from the Ginzburg-Landau (GL) theory.

A 76-year-old woman presented with sudden massive melena, and superior mesenteric arteriography showed an aneurysm in the middle colic artery (MCA). Because she had a history of right hemicolectomy and ligation of the inferior mesenteric artery (IMA) during open abdominal aortic aneurysm repair, embolization of the MCA aneurysm was considered to pose a risk comparable to that of colonic ischemia. A microballoon occlusion test during occlusion of the MCA confirmed retrograde visualization of the IMA branches through the collateral arteries by way of the left internal iliac artery, and embolization was successfully performed using microcoils. No colonic ischemia or aneurysm rupture occurred after embolization.
