Patent

CA 2218545

Devices, systems, and methods are provided for accessing the interior of the heart, and performing procedures therein while the heart is beating. A tubular access device (22) is positioned through an intercostal space and through a muscular wall of the heart. The access device (22) includes a balloon or flange for sealing (32) the penetration to prevent leakage of blood. An obturator (52) is positionable in the access device, and includes cutting means (60) located at its distal end. Elongated instruments are introduced through the access device to perform surgical procedures including septal device repair, ablation, and electrophysiological mapping.

Cette invention concerne des dispositifs, des systèmes et des procédés qui permettent d'avoir accès à l'intérieur du coeur et d'y pratiquer des interventions alors que le coeur est en train de battre. On positionne un dispositif d'accès tubulaire (22) en l'introduisant par un espace intercostal et par une paroi musculaire du coeur. Ce dispositif d'accès (22) comprend un ballonnet ou une bride qui obture (32) l'ouverture pour empêcher tout écoulement de sang. On peut placer un obturateur (52) dans le dispositif d'accès, comportant un système de coupe (60) situé à son extrémité distale. On introduit par le dispositif d'accès des instruments allongés pour pratiquer des interventions chirurgicales comprenant la réfection septale, l'ablation et la cartographie électrophysiologique.
