Description

Medical devices and related methods for closing a perforation in a bodily wall The medical device generally in-cludes a set of tissue anchors and an elongate tensioning member. Each anchor includes a crossbar having opposing ends and defining a longitudinal axis. A strand is connected to the crossbar at a location between the opposing ends and projects away from the longitudinal axis. The stand includes a distal end connected to the crossbar and a proximal end having a first connector. The elongate tensioning member is structured to selectively engage and disengage the first connector. The strands of the anchor are ca-pable of being tensioned and fixed together for closing the perforation. The tensioning member is removed after the strands are fixed together.

L'invention concerne des dispositifs médicaux et des procédés associés pour la fermeture d'une perforation dans une paroi corporelle. Le dispositif médical comprend en général un jeu d'ancrages tissulaires et un élément allongé de mise en tension. Chaque ancrage comprend une barre transversale comportant des extrémités opposées et définissant un axe longitudinal. Un brin est relié à ladite barre en un emplacement situé entre les extrémités opposées et dépasse de l'axe longitudinal. Le brin comprend une extrémité distale reliée à la barre transversale et une extrémité proximale comportant un premier connecteur. L'élément allongé de mise sous tension est structuré pour entrer en prise avec le premier connecteur, et se libérer de celui-ci, de façon sélective. Les brins d'ancrage peuvent être tendus et fixés ensemble pour fermer la perforation. L'élément de mise en tension est enlevé après la fixation des brins ensemble.
