Abstract
Disclosed is an apparatus for delivery of a stent for a vessel used for implanting the stent for a vessel in the blood vessel. The delivery system includes a protective sheath (1), inserted into the vessel of a living body, a catheter (2) inserted for back-and-forth movement in the protective sheath (1), a balloon (4) arranged on the outer peripheral surface towards the distal end side of the catheter (2), configured to be protruded from the distal end of the protective sheath (1), so that the balloon is expanded by a fluid supplied to the catheter (2), and a stent for a vessel (5) formed of a biodegradable material. The stent for a vessel (5) is mounted in a state contracted in diameter on the balloon (4) and is moved back and forth along with the balloon (4) relative to the protective sheath (1). The stent for a vessel has at least one end part temporarily held by a temporary holding member (23).
