Zusammenfassung:A method for determining a pressure gradient between proximal and distal locations within a vasculature of a patient. The method includes deploying an ancillary device within the vasculature. The ancillary device integrates a proximal sensor at the proximal location and a distal sensor at the distal location. The method further includes deploying, via a stent graft delivery system, a stent graft within the vasculature to obtain a deployed stent graft. The ancillary device is independent from the stent graft delivery system and the stent graft. The method further includes outputting proximal pressure data from the proximal sensor and indicative of pressure at the proximal location and distal pressure data from the distal sensor and indicative of pressure at the distal location. The method also includes determining the pressure gradient using the proximal and distal pressure data.
