  • Publication number: 20120226110
    Abstract: A volume of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of a volume can be determined based upon the sensing of the plurality of points without the use of other imaging devices. An implantable medical device can then be navigated relative to the mapping data.

  • Publication number: 20120108953
    Abstract: A method of treating cardiac tissue is provided, including positioning a first chamber of a medical device adjacent an atrial wall; directing a cryogenic coolant into the first chamber; anchoring the first chamber to the atrial wall through cryoadhesion; directing a distal portion of the medical device into the coronary sinus; and positioning a cardiac lead through at least a portion of the coronary sinus with the distal portion. The method may include measuring a temperature of the first chamber; removing the first chamber from the atrial wall once a predetermined threshold temperature of the first chamber is reached; anchoring a second chamber of the medical device to a portion of the coronary sinus; and/or perfusing blood flow through at least a portion of the second chamber.

  • Patent number: 8135467
    Abstract: Bio-impedance may be used for navigation systems to chronically implant pacing and defibrillation leads in the heart using a non-fluoroscopic position sensing unit (PSU). Such a system requires that a conductive material, such as a retractable helical tip-electrode, be exposed during implantation. Since the tip is retracted during implantation, this disclosure provides a modified distal portion employing at least one aperture (or “window”) for fluid exposure of the helix-electrode and a deployable internal sleeve for covering the aperture(s) when the helix-electrode is extended.

  • Patent number: 8108043
    Abstract: A method and an apparatus for treating cardiac arrhythmias are provided. An interval between first and second consecutive beats of a heart, having first and second chamber types, is determined. The heart is paced at a first rate if the first beat is from the first chamber type and the second beat is from the second chamber type and the interval is less than a predetermined amount of time or if the first and second beats are both from the second chamber type. The heart is paced at a second rate if the first beat is from the first chamber type and the second beat is from the second chamber type and the interval is more than the predetermined amount of time.

  • Publication number: 20110208075
    Abstract: A system for detecting a protrusion of a conductor within an anatomy is provided. The system can include a conductor, an insulator and a protrusion module to indicate a protrusion if the conductor protrudes from the insulator within the anatomy. The conductor can comprise a guide wire, a stylet, a pacing lead, a defibrillation lead, or other conductive instruments. The insulator can comprise a catheter, a sheath a cannula or other insulative instruments. The system can detect protrusion based on an impedance or an electrogram measurement.

  • Patent number: 7991467
    Abstract: Subcutaneous Implantable cardioverter-defibrillators (SubQ ICDs) are disclosed that are entirely implantable subcutaneously with minimal surgical intrusion into the body of the patient and provide distributed cardioversion-defibrillation sense and stimulation electrodes for delivery of cardioversion-defibrillation shock and pacing therapies across the heart when necessary. The SubQ ICD is implemented with other implantable and external medical devices and communicates to provide drugs and therapy in a coordinated and synergistic manner.

  • Publication number: 20110160557
    Abstract: A system and method are described for testing communication through a patient during implantation using telemetry coupling electrodes on a delivery catheter. In one example, at least two telemetry coupling electrodes may be placed on or within a delivery catheter to test conductive communication with external body electrodes during implantation. In some instances, the telemetry coupling electrodes of the delivery catheter may approximate the spacing of telemetry electrodes on an IMD. In this manner, testing conductively coupled communication with telemetry coupling electrodes of the catheter may be used to mimic the telemetry electrodes on the IMD and determine a target position and/or orientation of an electrode or electrodes of the IMD for successful conductive communication through the body.
