摘要：
The present disclosure relates to a device assembly and a method for treating heart failure by normalizing elevated blood pressure in the left atrium of a heart of a mammal. Disclosed herein is a transcatheter interatrial septum excision device assembly configured to create a sized interatrial aperture between the right and left atria of a heart for the relief of elevated left atrial pressure. The device assembly comprises a delivery catheter, a tissue stabilizer attached to a first catheter having a central lumen and a penetrating tip that permits passage of a guidewire, and a cutter attached to a second catheter having a central lumen that permits passage of the first catheter. Alternative configurations comprise a (third) catheter having a central lumen that permits passage of the aforementioned components to and from the right atrium, a tissue retention mechanism and an optional coaxial alignment mechanism.
