ABSTRACT:
A proximal anchor stent ring of an endoprosthesis includes proximal apexes, distal apexes, struts extending between the proximal apexes and the distal apexes, and anchor pins. The struts, the proximal apexes, and the distal apexes define an imaginary cylindrical surface. A pair of the anchor pins is located on the struts adjacent each of the proximal apexes, the anchor pins extending inwards from inside surfaces of the struts and protruding from the struts radially outward from the cylindrical surface. By locating the anchor pins inwards, the delivery profile of the proximal anchor stent ring is minimized.
