  • Publication number: 20210330333
    Abstract: An occlusion device with particular utility in occlusion of left atrial appendages is described. The occlusion device utilizes an inflatable balloon comprising a proximal portion to inflate with an inflation fluid delivered by an outer catheter body and conform to a shape of the left atrial appendage and a distal portion to fill with an adhesive delivered by an inner catheter body. The distal portion of the inflatable balloon sticks to the tissue wall of the left atrial appendage. The outer catheter body is configured to position the inner catheter body inside the outer catheter body.
