Title: LEAD TRACKING OF IMPLANTABLE CARDIOVERTER-DEFIBRILLATOR (ICD) AND CARDIAC RESYNCHRONIZATION THERAPY (CRT) DEVICES
Abstract:
Lead Tracking of Implantable Cardioverter-Defibrillator and Cardiac Resyπchronization Therapy Devices improve upon the process of implantation of ICD-CRT devices, placing their leads, and improving the information fed back to the device and/or clinician. Tracking of the placement of the leads during implantation is accomplished along with monitoring the leads. Benefits include reducing the risk and complication rate, simplifying implantation procedure, and enabling the extraction of vital data not previously available. Three dimensional tracking is employed to facilitate obtaining data that allows the surgeon to better visualize lead insertion and placement. Placement of the leads during a procedure requires use of an external tracking component along with means for tracking the leads. Transmitting antennas are provided, equal in number to the number of degrees of freedom of tracking required. Once leads are implanted, heart wall motion must be monitored via the tracking of the leads within a clinical or home environment.
