Abstract
Embodiments of the present disclosure are directed to apical closure systems, devices, and methods and systems for use thereof, for closing surgical openings or defects in the wall of the heart.
Claims26
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.
-7. (canceled)
The closure device of claim 7, wherein the cover comprises or carries a substantially self closing aperture for passing a guidewire therethrough.
(canceled)
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) an anchor portion coupled to the first portion and configured for bearing against the ventricle wall to prevent migration of the closure device in at least one direction following implantation, the anchor portion comprising a plurality of radially outwardly projecting independent spokes;
- and
- a cover for at least partially covering the outer surface of the support structure.
(canceled)
A device for closing an access opening in the ventricle wall of a heart comprising:
- a support structure having a lumen;
- a cover for at least partially covering the outer surface of the support structure;
- and
- a plug for substantially filling the lumen of the support structure.
