Embodiment Construction

[0017] The catheters, systems, and methods described herein can be used to perform various intrapericardial procedures, such as left atrial appendage transfusion, epicardial ligation for heart rhythm disorders, and tricuspid annuloplasty. Further information on these procedures and related systems and devices can be found in International Publication No. WO2014 / 015842Al, published October 2, 2014, entitled "DEVICES ANDMETHODS FOR TREATING FUNCTIONAL TRICUSPID VALVE REGURGITATION"; International Publication No. WO 2014 / 200764Al published on December 18, entitled "ENCIRCLING IMPLANT DELIVERY SYSTEMSAND METHODS"; and International Publication No. WO 2015 / 061775 published on April 30, 2015, entitled "ATRIAL APPENDAGE LIGATION" Al; the disclosure of which is hereby incorporated by reference in its entirety.

[0018] The direction "right" as used herein refers to the right side of the patient and the term "left" refers to the left side of the patient. Similarly, the terms "anterior...

Abstract

Disclosed herein is a delivery catheter having a three-dimensional curvature that facilitates access to the RAA from the inferior vena cava, positioning the distal end of the catheter so that the puncture site within the RAA is approximately parallel to the plane of the pericardial cavity, orienting the puncture device to avoid Orientation of the right coronary artery, aorta, pulmonary artery, and other structures to prevent "bystander" injury to these structures and provide sufficient rigidity to penetrate the wall of the RAA into the pericardial cavity.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 162,453, filed May 15, 2015, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to catheters and other devices for accessing the pericardial cavity through the right atrium and right atrial appendage. Background technique [0004] Some procedures require access to the pericardial space, such as ligation of the left atrial appendage, annular tricuspid valvuloplasty, or epicardial ligation for arrhythmias. One way to reach the pericardial space is by advancing a transvascular catheter through the right atrium and into the right atrial appendage, and passing the catheter through a puncture in the right atrial appendage into the pericardial space. However, these procedures may carry the risk of heart muscle or coronary artery laceration, among other risks. Cont...
