  • Patent number: 8545387
    Abstract: A method and related apparatus for the minimally invasive implantation about a heart of at least a deployable device such as a heart assist device or cardiac compression device. The method comprises the steps of performing a left thoracotomy or subxiphoid incision; obtaining access to the pericardial sac; making a generally linear incision in the pericardial sac; positioning an assembly having an insertion aperture member with an upper ring and a lower ring or flange and insertion tube having therein a deployable device. The apparatus of the present invention includes an insertion aperture member having an upper ring and a lower ring or flange; and an insertion tube having therein a deployable device adapted to be deployed from the insertion tube inside the pericardial sac via a generally linear incision.

  • Patent number: 7935045
    Abstract: The present invention provides methods, systems and devices that reduce dyskinesis and hypokinesis. The contoured heart assist device of the present invention includes a selectively inflatable end-systolic heart shaped bladder with one or more contoured supports configured to surround at least a portion of the heart and provide curvatures similar to the proper shape of the heart when the device is pressurized and one or more fluid connections in communication with the selectively inflatable end-systolic heart shaped bladder for pressurization and depressurization.

  • Patent number: 7871366
    Abstract: The present invention provides methods, systems, kits and devices that reduce dyskinesis and hypokinesis. For example, the direct compression cardiac device may be positioned about at least a portion of a heart, and includes a resilient inner panel in contact with at least a portion of the heart periphery, one or more resilient members positioned about the resilient inner panel and at least partially surrounded by an expandable outer panel. The resistance supplied by the inner panel to the heart may be modulated to control the end-diastolic heart volume and remodel the heart, the resistance supplied by the expandable outer panel to the heart may be modulated to control the end-systolic heart volume and remodel the heart or both.
