  • Publication number: 20190217005
    Abstract: A method for implanting a cardiac support device (CSD) on a patient's heart. An amount of contrast agent sufficient to cause structures on the heart to be visible upon fluoroscopic or other imaging is introduced into the pericardial space surrounding the heart. The heart and contrast agent are imaged to provide a visual indication of the location of the structures of the heart. The CSD is placed on the heart using the visual indications provided by the imaging.

  • Patent number: 10307252
    Abstract: An apparatus for placing a cardiac support device (CSD) on a heart. The apparatus includes a body, a deployment mechanism on the body for supporting the CSD in an open position for placement on the heart, and a release mechanism coupled to the deployment mechanism for releasably mounting the CSD to the deployment mechanism. The release mechanism includes a release element for releasably engaging the CSD, and a release actuator coupled to the release element for actuating the release element to release the CSD.

  • Publication number: 20180000381
    Abstract: A heart size measuring tool includes a tubular body, a flexible measuring cord having length indicia, a measuring cord support mechanism movable between retracted and extended states with respect to the body, and an actuating mechanism to move the measuring cord support mechanism. When in the retracted state the measuring cord support mechanism is positioned within the tubular body with the measuring cord in a collapsed position. When the measuring cord support mechanism is in the extended state the measuring cord extends around a portion of a heart to be measured. A scale on the body can be used in connection with the indicia on the measurement cord to provide a reading of the heart size.
