    Abstract: A delivery system and method for percutaneous aortic valve (PAV) replacement and apparatus used therein. A temporary aortic valve including a reversibly expandable occluding means surrounds a central catheter mechanism. The temporary valve is positioned within the ascending aorta, just above and downstream from the coronary ostia. The occluding means is configured such that, when fully expanded against the aortic wall, gaps are left that promote continuous coronary perfusion during the cardiac cycle. The temporary valve substitutes for the function of the native aortic valve during its replacement. The native aortic valve is next dilated, and then ablated through deployment of low profile, elongated, sequentially delivered stents. The stent(s) displace the native tissues and remain within the aortic annulus to receive and provide a structure for retaining the PAV. The PAV is delivered, positioned and deployed within the stent(s) at the aortic annulus with precision and relative ease.

    Abstract: A method of calibrating a robotic device, such as a cardiac catheter, including oscillating the device on an actuation axis by applying an oscillation vector at an oscillation frequency. While oscillating, a location of the device is periodically measured to generate a plurality of location data points, which may express the location of the device relative to a plurality of measurement axes. The location data points are then processed using a signal processing algorithm, such as a Fourier transform algorithm, to derive a transfer function relating a position of the device to a movement vector for the actuation axis. The transfer function may be resolved into and expressed as a calibration vector for the actuation axis, which may include one or more components, including zero components, directed along each of the measurement axes. The process may be repeated for any actuation axes on which calibration is desired.

    Abstract: A system to navigate an imaged subject in relation to an acquired image of the imaged subject is provided. The system includes an intracardiac echocardiography (ICE) imaging system having a transducer operable to acquire image data so as to create a four-dimensional image model of the imaged subject. The model is defined in spatial relation and orientation relative to an image coordinate system. A tracking system is operable to track movement and orientation of the transducer through the imaged subject relative to a tracking coordinate system. A controller is electrically connected in communication with the imaging system and the tracking system. The controller is operable to register the image coordinate system with the tracking coordinate system, and to calibrate the image coordinate system and the tracking coordinate system relative to a common reference having fiducials of known spatial relation.
