The flat stencil (2) of the future stent constructive elements is divided into two parts (4, 5) by the central vertical axis (3). In the middle part of the stencil (2) a cross-member (6) with the connecting carriers (7, 8, 9, 10) is executed to be fastened to the winding outlines peripheral parts (11, 12) neighboring with it. The cross-member (6) can be executed in several variants. Upon the expansion of the stent, the cross-member (6) with the connecting carriers (7, 8, 9, 10) covers the pair vessels carina area safely enough, held by the stent branches semi-circles (12). Some of the semi-circles (12) sections of the stent branches outlet outward sides (in relation to the blood flow) are relatively rigid bands width, the other semi-circles (12) sections of the stent branches outward sides are executed as the weakened ones (75) at the expense of decreasing the width of the relatively rigid bands, fastening reinforced and weakened semi-circles (12) between themselves. This creates "bell-mouthed" effect on the stent end faces upon its placing in a vessel. |
