    • A branch vessel in a human patient is located or mapped using in vivo tracked field sensors where in one variation the sensor positions can be located by determining the positions of the sensors relative to a plurality of magnetic field sources of known location. This approach is used, for example, in locating the opening in a renal artery and positioning the proximal end of the AAA stent-graft adjacent to the opening. In another example, the sensors are tracked along the inner wall of an aneurysm and the acquired sensor location data processed to map the contour of the aneurysm to size a prostheses for spanning the aneurysm. The portions of the vessel adjacent the aneurysm also can be mapped. In a further embodiment, an in vivo sensor is positioned in a deployed prosthesis to create a reference for a prosthetic member having a sensor to track to during cannulation of the deployed prosthesis with the prosthetic member.
    • 使用体内跟踪场传感器定位或映射人类患者中的分支血管,其中在一个变化中,可以通过确定传感器相对于已知位置的多个磁场源的位置来定位传感器位置。 例如,该方法用于将肾动脉中的开口定位并将AAA支架移植物的近端定位成与开口相邻。 在另一示例中,沿着动脉瘤的内壁跟踪传感器,并且处理所获取的传感器位置数据以映射动脉瘤的轮廓以使用于跨越动脉瘤的假体尺寸。 邻近动脉瘤的血管部分也可以被映射。 在另一实施例中,体内传感器定位在部署的假体中,以为具有传感器的假体构件创建参考,所述假体构件具有在用所述假体构件插入所展开的假体期间跟踪的传感器。
