Title
(EN) TISSUE ANCHORS AND PERCUTANEOUS TRICUSPID VALVE REPAIR USING A TISSUE ANCHOR
(FR) ANCRAGES TISSULAIRES ET RÉPARATION DE VALVE TRICUSPIDE PERCUTANÉE UTILISANT UN ANCRAGE TISSULAIRE
Abstract
(EN)
The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods of identifying a suitable location on the tricuspid annulus, placing a wire across the tricuspid annulus at such an identified location, deploying a tissue anchor across such an identified location, deploying two or more tissue anchors and coupling the tissue anchors with a flexible tensioning member, and applying tension to a flexible tensioning member that is coupled with the two or more tissue anchors, plicating tissues between each pair of the two or more tissue anchors, and reducing the circumference of the tricuspid annuls. As a result, a regurgitation jet is reduced or eliminated.

La présente invention concerne des dispositifs et des procédés de traitement de régurgitation de valve tricuspide. De manière spécifique, un aspect de la présente invention concerne des dispositifs et des procédés pour identifier un emplacement approprié sur l'anneau tricuspide, placer un fil à travers l'anneau tricuspide audit emplacement identifié, déployer un ancrage tissulaire à travers ledit emplacement identifié, déployer au moins deux ancrages tissulaires et accoupler les ancrages tissulaires à un élément de tension souple, et appliquer une tension à un élément de tension souple qui est accouplé à au moins deux ancrages tissulaires, plisser des tissus entre chaque paire des au moins deux ancrages tissulaires, et réduire la circonférence de l'anneau tricuspide. En conséquence, un jet de régurgitation est réduit ou éliminé.
