Abstract
A technique for accessing a pericardial space of a heart includes attaching a grip to a pericardium with adhesive, grasping the grip, drawing the pericardium away from the heart, and perforating the pericardium. The grip may consist solely of an adhesive. In other embodiments, other structures for the grip are used, including anchors, suture loops, and gripping tubes.

- 14. A pericardial access system for facilitating access to a pericardial space between a pericardium and an epicardium, the system comprising a tubular body defining an inner lumen adapted for slidably receiving a medical device therethrough and having a distal surface adapted for adhesively coupling to the pericardium, and a perforation instrument for perforating the pericardium, the instrument adapted to slide within the inner lumen and extend beyond the distal surface.
- 19. A pericardial grip that can be grasped for purposes of manipulating a pericardium, the pericardial grip comprising a graspable element and an adhesion means for facilitating adhesion of the graspable element to an exterior surface of the pericardium.
