摘要：
A closure device for sealing a patent foramen ovale (PFO) in the heart includes a left atrial anchor adapted to be placed in a left atrium of the heart, a right atrial anchor adapted to be placed in a right atrium of the heart, and a flexible elongate member adapted to extend through the passageway and connect the left and right atrial anchors. A delivery system for delivering the closure device includes a lock push tube for moving a lock along the elongate member and a wire release tube surrounding a wire for controlling movement of the right atrial anchor along the elongate member. The lock push tube and the wire release tube extend in a side-by-side relationship. A handle includes knobs for controlling the lock push tube and the wire. A device for retrieving a mis-deployed closure device includes a shaft portion and an expandable retrieval portion.
