Description

We propose a technique to prevent the migration using the biomedical tissue adhesion technology. In this paper, heat characteristic of stent and adhesive strength between stent and tissues were measured. The tissues were porcine arteiy and esophagus. Frequency, input current, and measurement time were 600 kHz, 3.0 A, and 180 s, respectively. As a result, the time that porcine artery and esophagus temperature reached at 80 ℃ were 136 s and 68 s, respectively. 0.02 MPa can be obtained as adhesive strength for both of them.
