Abstract
The invention is directed to a device and method for minimally invasive access to the pericardial space of a human or animal patient. The disclosed pericardial access device includes a penetrating body axially mobile within the lumen of a guide tube. The distal end of the guide tube includes a shoulder to buttress pericardial tissue drawn into the guide tube by a suction force applied to the guide tube lumen. The penetrating body is subsequently distally advanced within the guide tube to access the pericardium.
