Abstract:
Methods, apparatus, and systems for occluding a multiplicity of parallel membranes, such as found in a patent foramen ovale (PFO) . Methods, apparatus, and systems include the use of a positioning device (222,422) that can be seated on the limbus(114) of the septum secundum (SS). The positioning device includes a piercing member (27-0) that can pierce the SS and septum premium (SP). The positioning device also includes a fastening member (272) that can engage the SS and SP to fasten the tissues and thereby occlude a PFO.
