1. A method for occluding an atrial appendage comprising the steps of:
providing a device for occluding an atrial appendage comprising:
a shaft comprising a first hollow interior, an exterior surface, a first open end, a second open end, and an inflatable balloon coupled to the exterior surface,a catheter slidably positioned within the first hollow interior of the shaft, the catheter comprising a proximal end, a distal end, an exterior surface, a second hollow interior, and at least one opening communicating from the second hollow interior to the exterior surface adjacent to the distal end,a vacuum source operatively coupled with the second hollow interior of the catheter and capable of providing suction through the at least one opening, andan adhesive delivery device operatively coupled with the second hollow interior of the catheter and capable of delivering an adhesive through the at least one opening,wherein the inflatable balloon is configured to seal an ostium of the atrial appendage when the device is positioned within the atrial appendage and the balloon is inflated, and operation of the vacuum source creates a vacuum within the sealed atrial appendage, thereby causing the atrial appendage to collapse, andwherein the vacuum source is capable of providing suction through the second open end; delivering the shaft and catheter to the atrial appendage through a percutaneous intravenous route; inflating the balloon at the ostium of the atrial appendage such that the ostium is sealed; puncturing the walls of the atrial appendage at a first location by advancing the catheter through the second open end of the shaft; and collapsing the walls of the atrial appendage through operation of the vacuum source while the balloon is inflated to seal the ostium of the atrial appendage. |
