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.
Claims15
A method for accessing a pericardial space of a heart of a mammalian patient comprising:
- Guiding a catheter through a coronary sinus of the heart and to a cardiac vein which is distal to the coronary sinus;
- Advancing said catheter to a distal segment of the cardiac vein and further comprising sacrificing the distal segment of vein due to an occlusion resulting from the catheter;
- Intentionally puncturing the vein with the catheter to access the pericardial space;
- Performing a therapy or a diagnostic procedure in the pericardial space using the catheter and the puncture in the vein, wherein the therapy or diagnostic procedure includes at least one of delivery drugs to the pericardial space, delivery of a genetic agent to the pericardial space placement of electrodes into the pericardial space, removal of fluid from the pericardial space and infusion of fluid into the pericardial space, and
- Durably sealing the distal segment with the catheter.
A method for accessing a pericardial space of a heart of a mammalian patient comprising:
- Guiding a catheter through a coronary sinus of the heart and to a cardiac vein which is distal to the coronary sinus;
- Advancing said catheter to the cardiac vein;
- Intentionally puncturing the vein with the catheter to access the pericardial space, and performing a therapy or a diagnostic procedure in the pericardial space using the catheter and the puncture in the vein further comprising permanently sealing a distal segment of the cardiac vein.
A method for transvenously accessing a pericardial space between a serous layer and a fibrous layer of a pericardium of a heart in a mammalian patient, said method comprising:
- guiding a catheter through a coronary vein to a region adjacent the pericardial space;
- intentionally accessing the pericardial space with the catheter by penetrating the coronary vein and the serous layer;
- performing a therapy within the pericardial space using the catheter in the pericardial space, and
- sealing coronary vein, wherein the seal is a permanent seal of a distal segment of the coronary vein, wherein the catheter extends to the distal segment and is retracted from the patient after sealing the distal segment, and the permanent seal causes the distal segments to be sacrificed.
