Abstract: Several unique intra-cardiac pressure devices, placement catheters, methods of placement and methods of treating heart failure are presented. The intra-cardiac pressure devices presented allow sufficient flow from the left atrium to the right atrium to enable the relief of elevated left atrial pressure and resulting patient symptoms. The intra-cardiac pressure devices are made of a non-braided material.

Abstract: The invention is a septal implant that can accommodate variable thicknesses of the patient's atrial septum as well the variable thicknesses of septums across a population. The invention is able to accomplish this result by having flexible annular flanges that define a gap into which the septum fits. Due to the flexible nature of the annular flanges, the gap is adjustable.

Abstract: The present disclosure relates to a method and a device for treating heart failure by normalizing elevated blood pressure in the left and right atria of a heart of a mammal. The present disclosure includes methods for creating and maintaining an opening in the atrial septum. Tools for making an opening and enlarging the opening are also disclosed. Use of the techniques and tools described herein prolongs the patency of an intra-atrial pressure relief opening.

Abstract: Several unique intra-cardiac pressure vents, placement catheters, methods of placement and methods of treating heart failure are presented. The intra-cardiac pressure vents presented remain partially open under normal intra-cardiac pressures to allow sufficient flow from the left atrium to the right atrium to enable the relief of elevated left atrial pressure and resulting patient symptoms, and also limit the amount of flow from the right atrium to the left atrium by closing when the pressure in the right atrium exceeds the pressure in the left atrium by a predetermined amount.

The intracardiac pressure vents presented allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms but also limit the amount of flow from the right atrium to the left atrium to minimize the potential for thrombus or other embolic material from entering the arterial circulation.

Abstract: Devices and method are disclosed for reducing pressure in a patient's vena cava and in the right atrium of a patient's heart. A valve is implanted in the inferior vena cava (IFC) between the patient's renal veins and hepatic veins. When pressure in a patient's IFC reaches high levels, i.e., the pressure differential across the valve reaches high levels, the valve automatically closes or begins to close. The closing is caused by the pressure of the patient's blood moving one or more flaps in the valve to a closed or near-closed position. This prevents excessive pressure in the upper or superior vena cava and the right atrium of the patient's heart. The device also includes a pressure relief feature that opens and allows retrograde flow of blood if the pressure differential exceeds a yet higher pressure.

The intracardiac pressure vents presented allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms but also limit the amount of flow from the right atrium to the left atrium to minimize the potential for thrombus or other embolic material from entering the arterial circulation. In embodiments, the device comprises a core segment, an annular flange to engage one surface of the atrial septum and two other annular flanges to engage another surface of the atrial septum.
