Outline of Final Research Achievements

We tried experiments to apply Biocovered stent, which was prepared for medium and small caliber vessels and performed a transplant experiment, to large-diameter vessels. For large diameter vessels, self-expanding stents are mainstream not the balloon expandable stent, so Gianturco Z - stent which is a tracheal stent and 20 mm diameter silicone tube were used. As a result of trial and error, without removing Biotube produced subcutaneously, Z-stent was deployed in the lumen, and the silicone tube was inserted again into it. After 4 weeks, it was removed, and Biocovered stent for large diameter integrated Z-stent covered with autologous tissue membrane was able to be obtained.
