The invention relates to an implantable stent which can be used in the region of an arterial constriction said region being expandable by a balloon catheter. The stent is expandable and can be widened in a radial direction by virtue of the fact that the wall of the stent is formed at least in sections thereof from permanently deformable metal struts, whereby the stent consists of more than one tubular segment (10), wherein the segment (10) consist of metal struts (2) and wherein in each case two adjacent segments (10) are connected to each other by at least one pair of eyelets (6) and (7), where the eyelets (6) and (7) are connected to each other by being embedded in plastic and in this manner the segments (10) are held together, and where at least one of the metal struts (2) has a predetermined breaking point in the middle section of the segment (40), which predetermined breaking point is produced as a result of the fact that two strut sections (3) and (4) have eyelets (11), (12) respectively, which are connected to each other by being embedded in plastic, so that when they exceed a defined radial expansion, the metal struts (2) open as a result of the predetermined breaking point. |
