CLOSURE DEVICE AND METHODS AND SYSTEMS FOR USING SAME FIELD OF THE DISCLOSURE
Embodiments of the present disclosure are directed to closure devices, more particularly, apical closure devices and methods and systems for use thereof, for closing surgical openings or defects in the wall of the heart.
1 . A closure device implantable via an access opening in the ventricle wall of a heart and operative to close the access opening, the device comprising:
a support structure collapsible to a delivery state for implantation via the access opening, the support structure being self-expandable when released to expand to a deployed state in which the support structure defines at least (i) a first portion configured for positioning within the access opening, and (ii) a flange portion coupled to the first portion and configured for positioning substantially flat against the ventricle wall to prevent migration of the closure device in at least one direction following implantation; and a cover to at least partially cover the outer surface of the support structure.
