Abstract

Devices, systems, and methods are provided for accessing the interior of the heart and performing procedures therein while the heart is beating. In one embodiment, a tubular access device having an inner lumen is provided for positioning through a penetration in a muscular wall of the heart, the access device having a means for sealing within the penetration to inhibit leakage of blood through the penetration. The sealing means may comprise a balloon or flange on the access device, or a suture placed in the heart wall to gather the heart tissue against the access device. An obturator is removably positionable in the inner lumen of the access device, the obturator having a cutting means at its distal end for penetrating the muscular wall of the heart. The access device is preferably positioned through an intercostal space and through the muscular wall of the heart. Elongated instruments may be introduced through the tubular access device into an interior chamber of the heart to perform procedures such as septal defect repair and electrophysiological mapping and ablation. A method of septal defect repair includes positioning a tubular access device percutaneously through an intercostal space and through a penetration in a muscular wall of the heart, passing one or more instruments through an inner lumen of the tubular access device into an interior chamber of the heart, and using the instruments to close the septal defect. Devices and methods for closing the septal defect with either sutures or with patch-type devices are disclosed.

Claims

1. A method for accessing an interior chamber of a beating heart, said method comprising:

forming a penetration through a muscular wall of the heart into the interior chamber;

positioning a distal end of a tubular access device having an inner lumen through the penetration; and

forming a hemostatic seal between the device and the penetration to inhibit blood loss through the penetration, wherein the tubular access device is introduced percutaneously through an intercostal space.

2. A method as in claim 1, wherein the tubular access device is passed percutaneously through an intercostal space selected from the second, third, fourth, fifth, sixth or seventh intercostal space.

3. A method for accessing an interior chamber of a beating heart, said method comprising:

forming a penetration through a muscular wall of the heart into the interior chamber;

positioning a distal end of a tubular access device having an inner lumen through the penetration;

forming a hemostatic seal between the device and the penetration to inhibit blood loss through the penetration; and

performing a procedure on the heart using one or more instruments introduced through the inner lumen of the access device.

4. A method as in claim 3 wherein the procedure comprises repairing a septal defect in the heart.

5. A method as in claim 3 wherein the procedure comprises performing electrophysiological mapping.

6. A method as in claim 3 wherein the procedure comprises performing electrophysiological abalation.

7. A method as in claim 3 wherein the procedure comprises repairing a heart valve in the heart.

8. A method as in claim 3 wherein the procedure comprises removing a material from the heart selected from thrombi, vegetations, myxomas, and neoplasms.

9. A method for accessing an interior chamber of a beating heart, said method comprising:

forming a penetration through a muscular wall of the heart into the interior chamber;

positioning a distal end of a tubular access device having an inner lumen through the penetration; and

forming a hemostatic seal between the device and the penetration to inhibit blood loss through the penetration, wherein the heart remains beating throughout each of the steps of forming a penetration, positioning, and forming a hemostatic seal.

10. A method for accessing an interior chamber of a beating heart, said method comprising:

forming a penetration through a muscular wall of the heart into the interior chamber;

positioning a distal end of a tubular access device having an inner lumen through the penetration; and

forming a hemostatic seal between the device and the penetration to inhibit blood loss through the penetration, wherein the penetration is formed by an obturator removably positioned in the inner lumen of the tubular access device.

11. A method for accessing an interior chamber of a beating heart, said method comprising:

forming a penetration through a muscular wall of the heart into the interior chamber;

positioning a distal end of a tubular access device having an inner lumen through the penetration; and

forming a hemostatic seal between the device and the penetration to inhibit blood loss through the penetration, wherein ribs and sternum remain intact during each step of forming a penetration, positioning, and forming a hemostatic seal.
