1. A delivery system for facilitating orientation of a prosthesis in a bodily passage, the system comprising:
an inner cannula having proximal and distal regions;
an atraumatic tip having a proximal end, a distal end, and a central region disposed therebetween, where at least a portion of the atraumatic tip is coupled to the proximal region of the inner cannula;
a plurality of orientation struts having a retracted delivery state, an expanded deployed state, and a retracted withdrawal state,
wherein each of the plurality of orientation struts has an apex that is oriented proximally relative to the atraumatic tip in the retracted delivery state, is oriented radially outward relative to the atraumatic tip in the expanded deployed state, and is oriented distally relative to the atraumatic tip in the retracted withdrawal state.
