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 guide tube includes a deflecting mechanism for deflecting the distal end of the penetrating body. In use, a patient's pericardium is contacted with the distal end of the guide tube and suction is applied to form a pericardial bleb. The penetrating body is axially mobilized distally within the lumen of the guide tube until the deflecting mechanism deflects the penetrating body to cause the penetrating end of the penetrating body to enter the bleb of pericardial tissue at an angle oblique to the longitudinal axis of the guide tube.
