504 Fundamental study of stent heating methods for tissue adhesion treatment

Abstract

The aim of this study was to examine non-contact stent heating methods to adhere tissues to stents using an alternating magnetic field. We propose two kinds of coils (C-shaped and I-shaped), which apply the alternating magnetic field to the stent from the outside and inside, respectively. The speeds of the temperature rise in the stents were measured using J-type thermocouples for the C-shaped and I-shaped coils. The C-shaped coil took 90 s to reach 41℃, whereas the I-shaped coil took 19 s to reach 80℃.
