Patent ID: 11786388

Abstract:
The present embodiments provide delivery systems for facilitating orientation of a prosthesis in a bodily passage. In one example, a system comprises an inner cannula having proximal and distal regions, and further comprises an atraumatic tip having a proximal end, a distal end, and a central region disposed therebetween. At least a portion of the atraumatic tip may be coupled to the proximal region of the inner cannula. A plurality of orientation struts are provided having a retracted delivery state, an expanded deployed state, and a retracted withdrawal state. The plurality of orientation struts each have apices that are oriented proximally relative to the atraumatic tip in the retracted delivery state, are oriented radially outward relative to the atraumatic tip in the expanded deployed state, and are oriented distally relative to the atraumatic tip in the retracted withdrawal state.
