METHOD AND DEVICE FOR ACCESSING A PERICARDIAL SPACE
First Claim
Patent Images
1. A method for accessing a pericardial space of a heart of a mammalian patient comprising:
- advancing a catheter through a coronary sinus of the heart, a cardiac vein and to a distal branch of the cardiac vein;
intentionally puncturing the distal branch of the cardiac vein and a serous layer of a pericardium with the catheter to access the pericardial space between the serous and a fibrous layer of the pericardium, and performing a therapy or a diagnostic procedure in the pericardial space using the catheter extending through the puncture into the pericardial space.

Abstract
A method for accessing a pericardial space of a heart of a mammalian patient is disclosed comprising: guiding a catheter through a coronary sinus of the heart and to a cardiac vein; advancing said catheter to a distal segment of the cardiac vein; intentionally puncturing the vein with the catheter to access the pericardial space, and performing a therapy or a diagnostic procedure using the catheter an the puncture in the vein and using the pericardial space.

16. A method for inserting an access device into a pericardial space of a heart of a mammalian patient comprising:
-
advancing a catheter through a coronary sinus of the heart, a cardiac vein and to a distal branch of the cardiac vein;
distending the distal branch of the cardiac vein;
extending the access device from a distal end of the catheter to intentionally puncture the distal branch of the cardiac vein with the access device to access the pericardial space of the pericardium, and inserting the access device into the pericardial space;
removing the catheter from the patient and leaving at least a distal tip of the access device in at least one of the pericardial space and distal branch of the cardiac vein. - View Dependent Claims (17, 18, 19, 20)
