| 摘要 |
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.
