Abstract:
1. 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 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 interior to the exterior surface adjacent to the distal end; a vacuum source operatively coupled with the interior of the catheter and capable of providing suction through the at least one opening; an adhesive delivery device operatively coupled with the interior of the catheter and capable of delivering an adhesive through the at least one opening; and a plurality of needle wires, the proximal ends of which are coupled with the distal end of the catheter and slidably positioned within the interior of the shaft, the plurality of needle wires moveable between a closed configuration and an expanded configuration, and each needle wire comprising a hollow interior and an aperture at the distal end thereof, the hollow interior communicating between the interior of the catheter and the aperture; 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; wherein the vacuum source is capable of providing suction through the second open end; and wherein the adhesive delivery device is capable of delivering an adhesive through the apertures of the plurality of needle wires.
