ABSTRACT

Igaki-Tamai® Stent is a self-expanding stent. In the previous version a protective sheath was used to retain the stent on the delivery system. With the new stent delivery system, the Igaki-Tamai® Stent can be implanted by balloon inflation without sheath. In other words, the implantation of the Igaki-Tamai® Stent can be performed in the same way as any other balloon expandable stents. The Igaki-Tamai® Stent is held in the holding system shaped on the balloon. With the balloon inflated, the holding system opens and the stent is released and expanded against the vessel wall. After implantation, the Igaki-Tamai® Stent further expands gradually in the coronary artery.
