A medical assembly comprises an endoprosthesis expandable from a compressed configuration having an undeployed diameter to an expanded configuration having a deployed diameter, the endoprosthesis having a first end, a second end, and an intermediate portion between the first end and the second end, the endoprosthesis including a graft member and a plurality of ringed stent elements flexibly connected to each other solely via the graft member, the plurality of ringed stent elements including a first end element at the first end of the endoprosthesis and a second end element at the second end of the endoprosthesis, where expansion of each of the first and second end elements being unconstrained by any adjacent ringed stent elements when the endoprosthesis is in the compressed configuration; and a catheter assembly onto which the endoprosthesis is assembled, the catheter assembly including a balloon and a cover coupled to the balloon, the endoprosthesis being received over the balloon and the cover, the cover being configured to limit a tilt angle of the first and second end elements relative to a longitudinal axis of the endoprosthesis to be less than 35 degrees during expansion of the endoprosthesis from the compressed configuration to the expanded configuration. 13218140_1 (GHMatters) P110168.AU.1 Co Co coCo Co COCN Co C Co co co c C>) Co Co C C CNJ CNJ CNP0J N oCo Co Co Co No co co (No(
