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