First Claim
Patent Images
1. An apparatus for treating a patent foramen ovale (“
- PFO”
), comprising;
an elongate body member;
an elongate delivery device slidably housed within an inner lumen of the elongate body member;
an elongate piercing element slidably housed within the elongate delivery device;
a pusher member;
an implantable closure device releasably coupled with the pusher member, the pusher member and implantable closure device being slidably housed within the elongate piercing element;
a tissue engagement device pivotably coupled with the elongate body member with a first hinge and pivotably coupled with the elongate delivery device with a second hinge;
a hub element slidable over a guidewire;
at least two centering arms coupled with the hub element, the hub element and centering arms being slidable with respect to the elongate body member, wherein the centering arms are biased to deflect laterally outwards away from the elongate body member upon advancement of the hub element distally over the guidewire; and
an elongate core element coupled with the hub element and slidable with respect to the elongate body member.
