Abstract
Devices and methods for providing access to the pericardial cavity while reducing risk of myocardial damage. One method includes advancing a distal end of a puncture device towards the heart from a subxiphoid region of a patient wherein the distal end of the puncture device is atraumatic and comprises an energy delivery device; positioning the energy delivery device at a target site on a pericardium of the heart using ultrasound for imaging; and delivering energy from the energy delivery device to a tissue of the target site to create a channel to the pericardial cavity. The method may include repeating one or more of the above steps until the energy delivery device is located within the pericardial cavity. Some embodiments of the method include using supplemental means of monitoring, including medical imaging and using contrast fluid.
