Abstract
A patent foramen ovale closure device, method of delivering and a delivery system are provided. The device may include a closure device releasably connectable to an actuator The device may include a proximal segment (206), an intermediate segment (210) and a distal segment (208). When delivered, the proximal segment and intermediate segment form a first clip-shaped portion sized and configured to be positioned over a septum secundum of the patent foramen ovale, and the intermediate segment and distal segment form a second clip-shaped portion sized and configured to be positioned over a septum primum of the patent foramen ovale.
Claims47
A method of closing a patent foramen ovale having a septum primum and a septum secundum, comprising:
- providing a closure device having a proximal end, a distal end, a proximal segment, an intermediate segment and a distal segment, the proximal and intermediate segments defining a first clip-shaped portion and the intermediate and distal segments defining a second clip-shaped portion;
- and
- deploying the closure device within the patent foramen ovale such that the second clip-shaped portion is positioned over a tip of the septum primum and the first clip-shaped portion is positioned over a tip of the septum secundum, with the intermediate portion lying in a channel between the septum primum and the septum secundum;
- wherein the closure device when deployed exerts a force to draw the septum primum and septum secundum together.
A method of closing a patent foramen ovale having a septum primum and a septum secundum, comprising:
- providing a closure device having a proximal end and a distal end and having a generally elongate configuration and a clip configuration, wherein when the device is in its elongate configuration the proximal and distal ends are pulled away from each other and when the device is in its clip configuration the device has generally an S-shape,
- releasably attaching the device relative to a delivery device;
- delivering the closure device to the patent foramen ovale with the delivery device, the closure device being held relative to the delivery device in its elongate configuration;
- and
- deploying the closure device in the patent foramen ovale, wherein the device when deployed includes a first clip-shaped portion positioned around the septum secundum and a second clip-shaped portion positioned around the septum primum.
A device for closing a patent foramen ovale, comprising:
- a proximal end and a distal end;
- a proximal segment, an intermediate segment and a distal segment, wherein each of the segments is sequentially aligned;
- wherein the device has a generally elongate configuration and a clip configuration, the device when in its elongate configuration pulls the proximal and distal ends away from each other such that the proximal segment, intermediate segment and distal segment become relatively more linear, and the device when in its clip configuration draws the proximal segment and intermediate segment into a first clip-shaped portion sized and configured to be positioned over a septum secundum of the patent foramen ovate, and draws the intermediate segment and distal segment into a second clip-shaped portion sized and configured to be positioned over a septum primum of the patent foramen ovale.
A closure device for closing a patent foramen ovale, comprising:
- a proximal end, a distal end, a proximal segment, a distal segment, and an intermediate segment, wherein the device has a generally elongate configuration and a clip configuration, the device when in its elongate configuration pulls the proximal and distal ends away from each other such that the proximal segment, intermediate segment and distal segment become relatively more linear, and the device when in its clip configuration draws the proximal segment and intermediate segment into a first clip-shaped portion sized and configured to be positioned over a septum secundum of the patent foramen ovale, and draws the intermediate and distal segment into a second clip-shaped portion sized and configured to be positioned over a septum primum of the patent foramen ovale;
- and
- a covering provided on at least one of the segments of the device.
A device for closing a patent foramen ovate, comprising:
- a proximal end and a distal end;
- a proximal segment and a distal segment;
- wherein the device has generally a hook configuration wherein the distal segment is sized and configured to be positioned over a septum primum of the patent foramen ovale, and the proximal segment is sized and configured to extend through a tunnel of the patent foramen ovale with its proximal end positioned in the right atrium.
A system for delivering a closure device to a patent foramen ovale, comprising:
- a deployment catheter having a proximal end and a distal end;
- an actuator extending through the deployment catheter;
- and
- a closure device releasably attached to the actuator, wherein the actuator is adapted to advance the closure device from the distal end of the deployment catheter and position a distal segment of the closure device over a septum primum of the patent foramen ovale and position a proximal segment of the closure device over a septum secundum of the patent foramen ovale, the closure device being actuatable to pinch together the septum primum and septum secundum once delivered.
