Abstract
A method and apparatus are disclosed for a needle for gaining access to the pericardial cavity of a heart. The needle includes an elongate member (e.g. a main shaft) defining a lumen and a side-port in fluid communication with the lumen; a blunt atraumatic tip for delivering energy for puncturing tissue; and a guiding surface (e.g. a ramp) for directing a device (e.g. a guidewire) through the side-port. The method includes using the needle for tenting a pericardium and delivering energy for puncturing the pericardium, and advancing a guidewire or other device through the needle and into the pericardial cavity.
