Abstract
The radially expandable prosthesis for implantation in a lumen shows an inner and an outer surface and comprises a tubular wall composed of elongated struts (1, 2, 4) with a predetermined strut width. The struts are arranged to enable an expansion from a non-expanded state of the prosthesis to an expanded state. At least a number of the struts further show at least one location (5) provided with at least one hole (6) at the outer surface of the prosthesis. In order to maintain the required radial and fatigue strength of the prosthesis when providing the holes (6) without reducing the flexibility of the prosthesis and without increasing the additional amount of material therefor to a too large extend, the struts have at said locations an increased width (W.sub.2) larger than the predetermined width (W.sub.1) of the strut before and/or after said location (5).
