Abstract
Devices and methods for providing access to the pericardial cavity while reducing risk of myocardial damage. One method includes using an apparatus to apply pressure to a parietal pericardium, retracting the apparatus, and puncturing the parietal pericardium by delivering electrical energy using a puncture device. Another method includes moving a portion of parietal pericardium away from a surface of myocardium of the heart and puncturing the parietal pericardium by delivering electrical energy using a puncture device. The methods may include a step of confirming that the puncture device is at least partially within the parietal cavity by injecting or aspirating fluid through a lumen in the puncture device or measuring the pressure or electrical impedance at the distal end of the puncture device.
