Vessel Position and Configuration Imaging Apparatus and Methods
First Claim
1. A method of real time monitoring the position of a portion of a second vessel, which branches from a first vessel in a human patient comprising:
- acquiring a multi-dimensional data set of a portion of first and second vessels where the second vessel branches from the first vessel;
securing at least one marker to one of the first and second vessels in the vicinity of where the second vessel branches from the first vessel;
determining the position of the marker in real time; and
updating the position of a portion of the three-dimensional data set relative to the juncture between the first and second vessels in real time based on change in position of the marker.

Abstract
One or more markers or sensors are positioned in the vasculature of a patient to facilitate determining the location, configuration, and/or orientation of a vessel or certain aspects thereof (e.g., a branch vessel), determining the location, configuration and/or orientation of a endovascular devices prior to and during prosthesis deployment as well as the relative position of portions of the vasculature and devices, generating an image of a virtual model of a portion of one or more vessels (e.g., branch vessels) or devices, and/or formation of one or more openings in a tubular prosthesis in situ to allow branch vessel perfusion when the prosthesis is placed over one or more branch vessels in a patient (e.g., when an aortic abdominal artery stent-graft is fixed to the aorta superior to the renal artery ostia).
