Combined cardiac and respiratory motion compensation for atrial fibrillation ablation procedures

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a method to automatically compensate for both heart (cardiac) and breathing (respiratory) movements during atrial fibrillation ablation procedures. It uses imaging data to track the position of catheters within the heart in real time and adjusts for natural body movement, improving the accuracy of the procedure.

Use CasesContent extracted from patent full text and abstract with AI.

• Improving precision in atrial fibrillation ablation surgeries
• Assisting electrophysiologists in catheter navigation within the heart
• Enhancing mapping and treatment of other cardiac arrhythmias
• Use in advanced cardiac imaging systems for interventional procedures

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces errors due to patient movement (heartbeat and breathing) during surgery
• Increases the success and safety of ablation procedures
• Enables more precise targeting of cardiac tissue
• Potentially reduces surgery time and related risks
• Improves outcomes for patients undergoing treatment for atrial fibrillation

Patent Abstract

A method for compensating cardiac and respiratory motion in atrial fibrillation ablation procedures includes (a) simultaneously determining a position of a circumferential mapping (CFM) catheter and a coronary sinus (CS) catheter in two consecutive image frames of a series of first 2-D image frames; (b) determining a distance between a virtual electrode on the CS catheter and a center of the CFM catheter for a first image frame of the two consecutive image frames, and for a second image frame of the two consecutive image frames; and (c) if an absolute difference of the distance for the first image frame and the distance for the second image frame is greater than a predetermined threshold, compensating for motion of the CFM catheter in a second 2-D image.
