  • Publication number: 20080021266
    Abstract: The following relates to catheter-based devices, systems, and methods for minimally-invasively delivering an inflatable pericardial support into the pericardial space of a mammalian myocardium. The devices and systems include extending and positioning plural support members through a catheter into the pericardial space and then positioning the inflatable member on the epicardial surface of the myocardium. Once positioned, fluid can be delivered to the inflatable member to provide a confining pressure to the myocardium.

  • Publication number: 20070239066
    Abstract: Devices and methods for transplanting tissue for the purpose of regeneration, for treating a patient having injured myocardial tissue, and/or for improving cardiac function through cell regrowth. More specifically, the devices and methods obviate the need for cellular alteration. The devices comprise a hollow tube with a sharp distal end, a stylet that is disposed and movable within the hollow tube, and a stopping device that constrains movement of the stylet. The methods comprise removing intact tissue from a first region of a mammalian organ and implanting the tissue in a second region of the same organ.
