Abstract:
A method for implanting a medical device between tissue comprises the steps of providing a catheter having a body and a distal end thereof wherein the catheter includes an implantable device comprising a housing having a proximal end and a distal end and a longitudinal axis. The implantable device further includes a first set of anchoring members operatively connected to the proximal end of the housing and a second set of anchoring members operatively connected to the distal end of the housing. Both sets of anchoring members are movable between a collapsed position and a deployed position. Each set of anchoring members includes ring members connected to a housing of the device. Further steps of the method include inserting the distal end of the catheter into tissue and disposing the medical device at least partially from the distal end of the catheter. The first set of anchoring members are moved from the collapsed position to the deployed position and one side of the tissue is engaged with the tissue engaging surfaces of each ring member of the first set of anchoring member. The medical device is further disposed completely from the distal end of the catheter wherein the second set of anchoring members are moved from the collapsed position to the deployed position and the other side of the tissue is engaged with the tissue engaging surfaces of each ring member of the second set of anchoring members.
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 catheter introduction apparatus provides an ultrasound assembly for emission of ultrasound energy. In one application the catheter and the ultrasound assembly are introduced percutaneously, and transseptally advanced to the ostium of a pulmonary vein. An anchoring balloon is expanded to center an acoustic lens in the lumen of the pulmonary vein, such that energy is converged circumferentially onto the wall of the pulmonary vein when a transducer is energized. A circumferential ablation lesion is produced in the myocardial sleeve of the pulmonary vein, which effectively blocks electrical propagation between the pulmonary vein and the left atrium.
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.

Abstract:
A method for mapping includes receiving electrical inputs measured by a probe at respective locations in a chamber of a heart of a subject. The electrical inputs are processed to identify complex fractionated electrograms. At each of the respective locations, a respective contact quality between the probe and a tissue in the chamber is measured. A map of the complex fractionated electrograms in the chamber is created using the electrical inputs and the measured contact quality.
