Devices for less invasive intracardiac interventions

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