Abstract

A device for accessing an anatomic target area surrounded by a wall includes an elongated body having a passage longitudinally extending therethrough. An arm extends from the distal end of the elongated body, and does not obstruct the passage of the elongated body. A tooth member is disposed on an outer surface of the arm. The tooth member includes a penetrating end configured to engage the wall surrounding the target anatomic area. When used for accessing the pericardial space, the elongated body particularly the side of the arm, can be positioned against the parietal pericardium. The penetrating end engages the parietal pericardium. Once engaged, a working space is created by lifting the parietal pericardium. Other devices then can be introduced through the passage of the elongated body and into the pericardial space to perform a variety of procedures inside a patient.
