Company Summary

LAATech is developing a percutaneously-implantable device to fill the left atrial appendage (LAA) so that it will not throw off blood clots, which may produce strokes, in patients suffering from atrial fibrillation. This device represents a significant advance over other technologies because it conserves the LAA while filling it with a solid material that minimizes leakage. Our customers are hospitals and group purchasing organizations.
