A delivery system for selectively holding and deploying each end of an endoprosthesis includes a spindle having a spindle body. The spindle further includes proximal spindle pins and distal spindle pins extending radially outward from the spindle body. The delivery system further comprises a sleeve and a middle member sleeve. The endoprosthesis includes proximal spindle pin catches and distal spindle pin catches at proximal and distal ends of the endoprosthesis. The distal spindle pins extend into the proximal spindle pin catches and the sleeve radially constrains the proximal end of the endoprosthesis. The proximal spindle pins extend into the distal spindle pin catches and the middle member sleeve radially constrains the distal end of the endoprosthesis. Spindle pins may be omitted at one or both ends of the endoprosthesis, in some configurations.
