An apparatus and method for characterizing a region of interest (ROI) including measuring position and orientation data within the ROI; and generating a geometric data set to include one or more of: length, bifurcation location, angle and curvature characteristics of the ROI. Also, sequentially taking an image of a tool within the ROI; comparing tool dimensions with ROI dimensions; and estimating diameter, length, take-off angle, and/or tortuosity characteristics based on the comparisons.

Vascular branch characterization

A method for emulating prerecorded images may comprise acquiring at least one organ timing signal reading representing an activity state of an organ with at least one organ timing signal detector, acquiring a plurality of images with a medical imaging system, associating each of the plurality of images with an organ timing signal reading, removing any of the organ timing signal readings and associated images that are not representative of a normal organ configuration, and outputting a sequence of the representative images for a display.

Representative emulation of organ behavior

A method and system are provided that provide feedback regarding lead stability for a candidate target vessel, and provide guidance on a type of lead to be used. The method and system utilize a surgical navigation system and information regarding patient anatomy to predict lead stability within the patient anatomy. The method and system provide patient-specific force measurements for one or more vessels of a patient.

System and method for evaluating lead stability of an implantable medical device

Systems and methods are provided for use by implantable medical devices equipped to deliver multi-site left ventricular (MSLV) pacing. MSLV is associated with a relatively long post-ventricular atrial blanking (PVAB) period that might limit the detection of pathologic rapid organized atrial tachycardias (OAT). In one example, MSLV cardiac resynchronization therapy (CRT) pacing is delivered within a tracking mode. A possible atrial tachycardia is detected based on the atrial rate exceeding an atrial tachycardia assessment rate (ATAR) threshold. The device then switches to single-site LV pacing, thereby effectively shortening the PVAB to detect additional atrial events that might otherwise be obscured, and thereby permitting the device to more reliably distinguish organized atrial tachycardias (such as atrial flutter) from sinus tachycardia. The device may also employ an automatic mode switch (AMS) threshold that is set higher than the ATAR threshold for use in switching from tracking modes to nontracking modes.

Systems and methods for use by an implantable medical device for controlling multi-site CRT pacing in the presence of atrial tachycardia

Systems and methods are provided for use by implantable medical devices equipped to deliver multi-site left ventricular (MSLV) pacing. Sequential MSLV is associated with a relatively long post-ventricular atrial blanking (PVAB) period that might limit the detection of pathologic rapid organized atrial tachycardias (OAT). In one example, sequential MSLV cardiac resynchronization therapy (CRT) pacing is delivered within a tracking mode. A possible atrial tachycardia is detected based on the atrial rate exceeding an atrial tachycardia assessment rate (ATAR) threshold. The device then switches to either single-site LV pacing or simultaneous MSLV pacing, thereby effectively shortening the PVAB to detect additional atrial events that might otherwise be obscured, and thereby permitting the device to more reliably distinguish OATs (such as atrial flutter) from sinus tachycardia. The device may also employ an automatic mode switch (AMS) threshold set higher than the ATAR threshold for use in switching from tracking modes to nontracking modes.
