APPARATUS AND METHOD FOR TREATING BLEEDING ARISING FROM LEFT ATRIAL APPENDAGE

摘要

Bleeding arising from the left atrial appendage (LAA) can have fatal consequences because it can result in cardiac tamponade. The present invention provides apparatuses and methods for treating and preventing bleeding arising from the LAA, at the pre-hemorrhage and post-hemorrhage stages. In particular, catheters having inflatable catheter balloons are advanced into the LAA and the inflatable catheter balloons are inflated in and around the LAA in a manner that occludes the LAA ostium and the LAA cavity. Additionally, electromagnetic coils are present within the inflatable catheter balloons to create electromagnetic forces that help to further occlude the LAA ostium firmly. When the catheter balloons are inflated, these electromagnetic coils also expand. Alternatively, the LAA ostium can be occluded using electromagnetic coils present in an inflated endocardial catheter balloon and electromagnetic coils present in an inflated epicardial catheter balloon deployed around the circumference of the LAA ostium epicardially.
