  • Patent number: 9592058
    Abstract: A medical device implant for the left atrial appendage of a patient's heart, to prevent strokes. The device includes a cap that overlies the opening of the LAA connected to a bulb in the LAA. Dis-continuous segmented sails attached to the cap promote tissue growth over the device.
    Type: Grant
    Filed: February 21, 2012
    Date of Patent: March 14, 2017
    Assignee: Cardia, Inc.
    Inventors: Gary S. Erzberger, Dara Chin, Robert T. Sandgren, Michael Patrick Corcoran

  • Patent number: 8366741
    Abstract: The present invention is an occlusion device having a centering arm network that self-centers across a defect and can be retrieved and redeployed in situ. A self centering system allows the center of the occlusion device to remain properly positioned within the defect, which increases the effectiveness of the occlusion device. The self centering system is comprised of a plurality of centering arms which define a flexible intermediate zone. In addition, the occlusion device of the present invention has a plurality of right arms connected to the plurality of centering arms which make it possible to retrieve and redeploy the occlusion device in situ.

  • Publication number: 20120150218
    Abstract: An implantable device for occluding a septal defect has interleaved frame sections that allow flexibility to conform to a variety of defect geometries and provide reliable occlusion during endothelialization. Left and right frames connect to opposite ends of a floating connection post. The device is resiliently deformable and is biased into a natural state wherein, in situ in a variety of defect geometries, the device applies a sandwiching force to the tissue surrounding the defect that is relatively uniform across its diameter, improving stability and promoting occlusion.
