The invention generally relates to systems and methods for percutaneous closure of intra-cardiac openings, such as a patent foramen ovale (PFO). In one embodiment, a closure system includes an elongated member coated with a bonding material. The bonding material adheres to the intra-cardiac opening when energy is applied to the elongated member. The system may also include an energy riser, such as a protuberance on the surface of the elongated member or a modification to the surface of the elongated member. In another embodiment, the closure device includes a catheter containing the elongated member or a locator, such as a balloon or hook. The elongated member may be inserted into an intra-cardiac opening, such as a patent foramen ovale.
L'invention porte, de manière générale, sur des systèmes et sur des méthodes de fermeture percutanée d'orifices intracardiaques tels qu'un foramen ovale. Selon une forme d'exécution, un système de fermeture comprend un élément allongé recouvert d'un matériau de fixation. Ce matériau de fixation adhère à l'orifice intracardiaque lors de l'application d'une énergie sur l'élément allongé. Le système peut également comprendre un élément pour faire monter l'énergie, tel qu'une protubérance sur la surface de l'élément allongé ou une modification apportée à la surface de l'élément allongé. Selon une autre forme d'exécution, le dispositif de fermeture comprend un cathéter contenant l'élément allongé ou un dispositif de localisation tel qu'un ballonnet ou crochet. L'élément allongé peut-être inséré dans un orifice intracardiaque tel que le foramen ovale.
