A manufacturing method of a stent is disclosed which prevents a drug from being peeled off or separated due to stress concentration or distortion resulting from the expanding deformation of the stent so that the drug is further uniformly effective and further improved yields are expected when the stent is manufactured, and a coating device. The method has a non-coating portion forming process of preventing a bending portion from being coated with the drug by causing a nozzle to go past the bending portion when the nozzle reaches the bending portion and to move toward main strut portions. In the non-coating portion forming process, an adhesion amount of a coating solution is reduced while the nozzle is going past the bending portion.

A biological tissue closing device includes a clamper comprising a stick portion provided at a distal portion of a catheter for sticking to a biological tissue, and a sandwich member for sandwiching the biological tissue in cooperation with the stick portion, and an electric energy supply unit for supplying electric energy to the clamper. The biological tissue is fused by making the stick portion and the sandwich member of the clamper be electrode members, by sandwiching the biological tissue with the clamper and by supplying electric energy from the electric energy supply unit, wherein the clamper is configured so that each of the stick portion and the sandwich member are movable independently with respect to the catheter.
