Devices for less-invasive intracardiac interventions
First Claim
1. An assembly for visualization and access within a body cavity comprising:
- a sleeve having a distal end, a proximal end, and a lumen therebetween;
a scope having a shaft with a distal end and a proximal end, the shaft being slidably positionable in the lumen, a channel extending longitudinally through the shaft, and a lens in the channel near the distal end, a transparent bulb disposed at the distal end of the shaft outside of the channel and optically aligned with the lens.

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.

12. A contact scope for visualization within a body cavity comprising:
-
an elongate sheath having a distal end, a proximal end, a lumen therebetween, and a transparent bulb mounted to the distal end aligned with the lumen; and
a scope slidably positionable in the lumen, the scope having a shaft with a distal end, a proximal end and a channel therebetween, and a lens mounted in the channel near the distal end;
wherein the distal end of the shaft may be positioned within the lumen adjacent to the transparent bulb to allow viewing through the lens and the bulb.

positioning a visualization scope through a sleeve;
positioning a distal end of the visualization scope into the heart through a penetration in a wall thereof;
viewing the opening through the visualization scope;
sliding the sleeve into the opening; and
removing the visualization scope from the sleeve.
