Title
(EN) COMPLIANT ELECTRODE FOR PATENT FORAMEN OVALE CLOSURE DEVICE
(FR) ELECTRODE DEFORMABLE POUR DISPOSITIF DE FERMETURE D'UN FORAMEN OVALE PERMEABLE
Abstract
(EN)
A medical device for use in delivering RF energy to a tissue opening is disclosed. In one embodiment, the medical device comprises a compliant electrode. The compliant electrode can include a shape memory material, such as NITINOL, to facilitate the electrode having at least one relaxed orientation. The electrode can be deployed from a delivery shaft inside the left atrium, for example, of a heart through the delivery shaft. The electrode can be configured to substantially conform to the tissue proximate the tissue opening. After energy is applied to the tissue between the left and right electrodes, the left electrode can be removed from the left atrium by being received back into the delivery shaft and the delivery shaft thereafter removed from the opening.
(FR)
Dispositif médical permettant d'appliquer une énergie RF à une ouverture dans un tissu. Dans un mode de réalisation, ce dispositif médical comprend une électrode déformable, laquelle peut comprendre un matériau à mémoire de forme, tel que du NITINOL, qui lui permet de prendre plus facilement au moins une orientation à l'état de repos. L'électrode peut être déployée à partir d'une tige d'amenée dans l'oreillette gauche du coeur. Elle peut être conçue pour épouser sensiblement la forme du tissu à proximité de l'ouverture dans ce dernier. Après application de l'énergie au tissu entre les électrodes gauche et droite, l'électrode gauche peut être retirée de l'oreillette gauche par réintégration dans la tige d'amenée, puis retrait de ladite tige par l'ouverture.
