20080294174 | METHODS AND APPARATUS FOR PERICARDIAL ACCESS - An access tube has a central passage and at least one lumen extending axially between the central passage and an outside wall of the access tube. The lumen carries therein a piercing member for accessing an anatomic space, such as a pericardial space between the parietal pericardia and the visceral pericardia. While the access tube is positioned against the parietal pericardium, a distal end of the piercing member engages and penetrates the parietal pericardium. The distal end of the piercing member entering the anatomic space can then allow the piercing member to advance and form into a supporting structure to create a working space. After the working space is created, an access device can be introduced through the access tube into the pericardial space to perform a variety of procedures inside a patient. | 11-27-2008 |
