Abstract
A device is described for crossing the atrial septum to properly size a valve annulus for treatment or replacement, having a catheter with an expandable braided tubular structure attached at its distal end. The proximal and distal end regions of the braided tube have an open structure to allow blood flow to pass freely through the gaps or spaces between the braided fibers. The lumen within the tube includes a temporary, artificial valve that acts similar to a native valve, allowing blood to flow in one direction and preventing blood flow in the opposite direction.
