From: Occluding morphologically complicated left atrial appendage using the small-umbrella LAmbre device
The LAmbre LAA occlusion device. The schematic diagrams (A and B) and real-life products (C and D) of the LAmbre occlusion device. The upper part is the inner umbrella anchored inside the LAA. The lower part is the outer cover placed on the LAA orifice. The umbrella and the cover are connected by a short, flexible central waist. A and C The regular-sized device with a cover diameter 4–6 mm greater than the umbrella. B and D The small-umbrella device with a small umbrella and a large cover (diameter difference of 12–14 mm).
