Abstract

A device for treating a heart condition in a patient. The device has a body adapted and configured to self-expand from a radially collapsed configuration to an expanded configuration. In its expanded configuration, the device has a first section at a first end, a second section at a second end and a central portion extending between the first and second sections, the first and second sections each having diameters that increase with distance from the central portion toward the first and second ends, respectively. The body is configured to be delivered percutaneously to a patient'"'"'s heart and allowed to self-expand in an opening in a septum of the heart to dispose the first end in the left atrium, the second end in the right atrium and the central portion in the opening to permit blood to flow through the body from the left atrium to the right atrium.

Claims

1. A device for treating a heart condition in a patient, the device comprising:

a body adapted and configured to self-expand from a radially collapsed configuration to an expanded configuration, the device in its expanded configuration comprising a first section and a second section, wherein each of the first and second sections has a first end and a second end, and the first ends of both first and second sections join together and wherein the first and second sections each have diameters that gradually increase with distance from their first ends towards their second ends, and wherein the device in its expanded configuration also has an annular gap between first and second sections of the device, the first ends of the first and second sections positioned at a midpoint of the annular gap, and wherein the body has a centrally located passage extending through the first and second sections, the passage having a diameter of about 4-15 mm, the body being configured to be delivered percutaneously to a patient'"'"'s heart and allowed to self-expand in an opening in a septum of the heart to dispose the first section in the left atrium, the second section in the right atrium and the passage of the body to permit blood to flow from the left atrium to the right atrium.

2. The device of claim 1, further comprising a valve disposed in the body.

3. The device of claim 2, further comprising structure supporting the valve in the body.

4. The device of claim 2, wherein the valve is biased to a closed position.

5. The device of claim 4, wherein the valve is configured to open when pressure differential between the left atrium and the right atrium is 2 mm Hg or greater.

6. The device of claim 1, wherein the body comprises braided mesh.

7. The device of claim 1, wherein the first and second sections are sized and configured to engage the septum at the opening when the body is expanded in the opening.

8. The device of claim 1, wherein the body is elongated in the radially collapsed configuration.
