Abstract
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.

167. A percutaneous transluminal system for closing a cardiac opening, comprising:
-
a first catheter comprising a proximal end, a distal end, and a lumen extending from the proximal end to the distal end;
a second catheter at least partially enclosed within the lumen of the first catheter, the second catheter movable between a retracted state and a deployed state; and
a lining coupled to the first and second catheters, wherein in the retracted state of the second catheter the lining is positioned within the lumen of the first catheter, and wherein in the deployed state of the second catheter the lining inverts and is positioned outside the lumen of the first catheter. - View Dependent Claims (168, 169, 170, 171, 172, 173, 174, 175, 176, 227, 228, 229, 230)

177. A method for percutaneous transluminal closure of a cardiac opening in a patient, comprising:
-
inserting, into a heart of the patient, a system for closing the cardiac opening, the system comprising;
a first catheter comprising a proximal end, a distal end, and a lumen extending from the proximal end to the distal end;
a second catheter at least partially enclosed within the lumen of the first catheter, the second catheter movable between a retracted state and a deployed state; and
a lining coupled to the first and second catheters, wherein in the retracted state of the second catheter the lining is positioned within the lumen of the first catheter, and wherein in the deployed state of the second catheter the lining inverts and is positioned outside the lumen of the first catheter;
positioning the system proximate the cardiac opening with the second catheter in the retracted state; and
deploying the second catheter to invert the lining and position the lining within the cardiac opening. - View Dependent Claims (178, 179, 180, 181)
