摘要：
The invention generally relates to devices, systems, and methods for percutaneous closure of cardiac openings and obliteration of the cardiac cul-de-sacs. In one embodiment, a closure device includes a patch with an adhesive and/or a removable frame. The patch may be placed across a cardiac opening, such as a patent foramen ovale, or across a cardiac cul-de-sac, such as a left atrial appendage. In another embodiment, a closure device includes a balloon together with adhesives and/or substances for stimulating tissue growth coated on, or contained within, the balloon. The balloon may be inserted into a cardiac opening, such as the patent foramen ovale, or into a cardiac cul-de-sac, such as a left atrial appendage.
