Abstract

A device for sealing a patent foramen ovale (PFO) in the heart is provided. The device 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 an elongate member adapted to extend through the passageway and connect the left and right atrial anchors. The right atrial anchor preferably includes a plurality of arms and a cover attached to the arms. The left atrial anchor preferably also includes a plurality of arms and preferably does not include a cover. Preferably, the elongate member has a first end fixedly connected to the left atrial anchor and a portion, proximal to the first end, passing through the right atrial anchor. Preferably, the elongate member is flexible.

Claims

1-90. -90. (canceled)

91. A system for sealing a passage in a heart, the system comprising:

a delivery catheter capable of extending to a position near the passage;

a closure device capable of sealing the passage, the device including a first anchor adapted to be placed proximate a first end of the passage, a second anchor adapted to be placed proximate a second end of the passage, and a flexible elongate member adapted to extend through the passage and connect the first and second anchors; and

a cutting tool capable of extending over the flexible elongate member to a position near the second anchor.

92. The system of claim 91, wherein the cutting tool includes a guide member for guiding the flexible elongate member.

93. The system of claim 92, wherein the guide member includes a distal opening through which the flexible elongate member enters the cutting tool and a lateral opening through which the flexible elongate member exits the cutting tool.

94. The system of claim 92, wherein the cutting tool further includes a cutting element disposed around the guide member.

95. The system of claim 94, wherein the cutting element is movable relative to the guide member to cut the flexible elongate member as it exits the guide member through a lateral opening of the guide member.

96. The system of claim 91, further comprising a guide catheter capable of extending to a position near the passage.

97. The system of claim 91, further comprising a loading tube.

98. The system of claim 97, wherein the closure device is positionable within the loading tube in a collapsed state.

99. The system of claim 91, wherein the second anchor includes a plurality of second loop structures.

109. The system of claim 94, wherein the cutting element is formed of stainless steel.

110. The system of claim 94, wherein the cutting element includes a sharpened distal edge.

111. The system of claim 94, wherein the cutting tool includes a handle mechanism configured to move the cutting element relative to the guide member.

112. The system of claim 111, wherein the handle mechanism is configured to rotate the cutting element.

113. The system of claim 111, wherein the handle mechanism is configured to advance the cutting element distally.
