Abstract
A left atrial appendage (LAA) occlusion system and a method for occluding the LAA are disclosed. The LAA occlusion plug includes at least two expandable materials having shrunken and swollen states, two plates and a delivery tool configured to deliver the occlusion plug to the LAA. The LAA occlusion plug is configured to permanently occlude the LAA opening, such that blood clots cannot flow out of the LAA when the at least two hydrogels are in the swollen state. The LAA occlusion plug plates are configured to force the expandable materials to swell inwards in the axial direction and outwards in the radial direction such that the LAA occlusion plug is clipped to the LAA opening tissue.
