Flexible expandable sheet stent is intended for the better support of a diseased vessel wall on the basis of securing the very best characteristics and raise in the service ability of a stent in a vessel. The stent comprises constructive elements (7), preliminary formed in a shape of a stencil on the thin sheet metallic blank surface (5). The stent constructive elements (7) include a saw-shaped profile made of teeth (8) from which the relatively rig id band in a shape of consecutively united pockets is formed, the long twisting sides (9, 10) of the closed free loops and the short sides (11) of the close d ring outline. In a passage, formed of consecutively united pockets, a polyme r thread (21) with a fixed length loaded with medicinal preparations for local drugs delivery is deployed. The implantation of the stent in the vessel unde r the X-ray controls performed in such a way as to locate the relatively rigid band of consecutively united pockets on the side of the vessel wall adjoinin g the cardiac muscle.
