3 dimensional right atrial appendage curved catheter

摘要

The disclosed delivery catheter reaches the RAA from the inferior vena cava and positions the distal end of the catheter approximately parallel to the plane of the pericardial space at a penetrating place within the RAA and punctures the device through the right coronary artery, aorta, pulmonary artery , And to avoid other structures to promote prevention of paraeal damage to such structures and to provide sufficient hardness to enter the pericardial space through the RAA wall 3 Dimensional curvature. According to one embodiment, the curvature of the catheter directs the distal end of the catheter with a trajectory less than 36 from horizontal.
