1. An endoprosthesis comprising:
- a proximal anchor stent ring comprising;
proximal apexes comprising a first proximal apex;
distal apexes;
struts extending between said proximal apexes and said distal apexes, wherein a first strut and a second strut of said struts extend distally from said first proximal apex; and
anchor pins located on said struts adjacent said proximal apexes, said anchor pins comprising a first anchor pin extending from said first strut adjacent said first proximal apex and a second anchor pin extending from said second strut adjacent said first proximal apex and directly opposite said first anchor pin, wherein said first strut comprises an inside surface inward to a curvature of said first proximal apex, said first anchor pin extending inwards from said inside surface of said first strut, and wherein said second strut comprises an inside surface inward to said curvature of said first proximal apex, said second anchor pin extending inwards from said inside surface of said second strut, wherein said proximal apexes and said anchor pins define spindle pin catches comprising a first spindle pin catch defined by said first proximal apex, said first anchor pin, and said second anchor pin.

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.
