Abstract: A position sensing system includes a probe adapted to be introduced into a body cavity of a subject. The probe includes a magnetic field transducer and at least one probe electrodes. A control unit is configured to measure position coordinates of the probe using the magnetic field transducer. The control unit also measures an impedance between the at least one probe electrodes and one or more points on a body surface of the subject. Using the measured position coordinates, the control unit calibrates the measured impedance.

Abstract: A resonant circuit is incorporated in a stent, which implantable in a pulmonary vein using known cardiac catheterization techniques. When an external RF field is generated at the resonant frequency of the stent, RF energy is re-radiated by the stent toward electroconductive tissue in the wall of the pulmonary vein, and produces a circumferential conduction block. The stent can be made of biodegradable materials, so that it eventually is resorbed. Following an ablation procedure, the stent may be left in situ. Repeated ablation can be performed using the inserted stent until it has been determined that the desired lesions have been formed. Furthermore, the same stent can potentially be used even years after being inserted should the treated arrhythmia reoccur or a new arrhythmia develop, thereby possibly obviating the need for an invasive procedure at that future time.

Abstract: A catheter introduction apparatus provides an optical assembly for emission of laser light energy. In one application, the catheter and the optical assembly are introduced percutaneously, and transseptally advanced to the ostium of a pulmonary vein. An anchoring balloon is expanded to position a mirror near the ostium of the pulmonary vein, such that light energy is reflected and directed circumferentially around the ostium of the pulmonary vein when a laser light source is energized. A circumferential ablation lesion is thereby produced, which effectively blocks electrical propagation between the pulmonary vein and the left atrium.

Abstract: A method for telemetrically measuring a parameter in a patient's heart comprises the steps of imaging the heart and identifying an implantation site in the heart. An opening is created in the tissue at the implantation site. A sensor comprising a housing, a membrane at one end of the housing wherein the membrane is deformable in response to the parameter, and a microchip positioned within the housing and operatively communicating with the membrane for transmitting a signal indicative of the parameter is provided. The sensor is placed in the opening and the parameter is telemetrically measured from outside of the patient's body based on the transmitted signal by the sensor. The sensor is also telemetrically powered from outside of the patient's body. A signal charging and reading device is placed outside of the patient's body for telemetric powering and signal reading with respect to the sensor. In an alternative embodiment, the sensor has a tapered distal end and a tissue piercing tip for direct implantation into tissue. Alternative embodiments of this sensor include helical threads on the tapered distal end for threading the sensor into tissue and a plurality of tissue barbs for direct and firm anchoring of the sensor in tissue.

Abstract: Epicardial fat pad ablation is conducted using a catheter inserted through the chest wall, using ultrasound ablation, or using a catheter fitted with a directional ultrasound transducer and capable of being aligned with the epicardium. The epicardial fat pad locations are determined using noninvasive imaging methods, or using electrical maps. These locations are then displayed on maps or images of the heart, and thus targeted for minimally invasive or non invasive therapy. The methods of the present invention are less invasive than conventional methods of ablation, and permit flexible access to substantially any point on the epicardium.
