Abstract
Devices, systems and methods for atrial appendage occlusion. A device is described with respect to non-surgically occluding the left atrial appendage with minimal invasiveness. Additionally, a system and method are described for using the device to perform the left atrial appendage occlusion procedure.
Claims20
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, and
- an 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, and
- wherein 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;
- and
- inflating the balloon at the ostium of the atrial appendage such that the ostium is sealed.

A method for occluding an atrial appendage, comprising the steps of:
- percutaneously and intravascularly introducing a portion of a device for occluding an atrial appendage through a blood vessel, into a heart, and into the atrial appendage, the device comprising:
- a shaft defining a first hollow interior therethrough, an exterior surface, a first open end, a second open end, and having an inflatable balloon coupled thereto, the inflatable balloon configured to seal an ostium of the atrial appendage upon inflation;
- a catheter slidably positioned within the first hollow interior of the shaft, the catheter comprising a proximal end, a distal end, an exterior surface, and defining a second hollow interior therethrough and at least one opening at or near a distal end of the catheter in communication with the second hollow interior;
- an adhesive delivery device coupled with the second hollow interior of the catheter and configured to deliver an adhesive through the at least one opening;
- and
- a vacuum source operatively coupled with the second hollow interior of the catheter and capable of providing suction 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;
- and
- wherein the vacuum source is capable of providing suction through the second open end;
- positioning the balloon at the ostium of the atrial appendage;
- and
- inflating the balloon to seal the ostium.
