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.
A method for accessing an interior chamber of a beating heart, said method comprising:
A method for closing a cardiac septal defect in a heart, said method comprising:
An improved method for closing a cardiac septal defect of the type in which a patch of material is secured over the defect, wherein the improvement comprises introducing and securing the patch through an inner lumen of a tubular access device positioned through a muscular wall of the heart.
An improved method for closing a cardiac septal defect of the type in which a pericardium patch is secured over the defect, wherein the improvement comprises harvesting the pericardium patch using instruments introduced through one or more intercostal spaces, and introducing and securing the patch in the heart through an inner lumen of a tubular access device positioned through a muscular wall of the heart.
An improved method for closing a cardiac septal defect of the type in which the defect is sutured closed, wherein the improvement comprises suturing the defect using an instrument introduced through an inner lumen of a tubular access device positioned through a muscular wall of the heart.
A method of forming a lesion in heart tissue of a patient, comprising:
A method of ablating cardiac tissue, comprising:
A method of forming a lesion in heart tissue of a patient, comprising:
