Patent

CA 2671157

Systems, devices and methods for treating internal tissue defects, such as septal defects, are provided. An exemplary method of treating an internal tissue defect, specifically a method of closing a patent foramen ovale (PFO), can include passing a closure element from a right atrium through a septal wall in a first location and into the left atrium. A capture device, which can be configured as a snare-like device, can be used to capture the closure element in the left atrium and pull the closure element back through the septal wall in a different, second location, such that the closure element is routed over the PFO. The closure element can then be anchored and/or locked against the septal wall such that the PFO is at least partially closed.

Cette invention concerne des dispositifs et des méthodes de traitement de malformations tissulaires, telles que des malformations congénitales du septum inter-ventriculaire. A titre d'exemple, un procédé de traitement d'une malformation tissulaire interne, plus précisément une méthode consistant à fermer un foramen ovale persistant (PFO), peut consister à faire passer un élément de fermeture depuis une oreillette droite à travers la cloison septale en un premier point dans l'oreillette gauche. Un dispositif de saisie, par exemple du type à anse, peut être utilisé pour saisir l'élément de fermeture dans l'oreillette gauche et le faire passer de nouveau à travers la cloison septale par un second point de telle sorte que l'élément de fermeture est acheminé par dessus le PFO. Cet élément peut ensuite être fixée et/ou immobilisés contre la paroi septale de sore que le PFO est au moins partiellement fermé.
