Preclinical Results


Bench testing and acute/chronic animal studies have been implemented to support the first-in-human study. Large animal studies in an ovine acute heart failure model and in a chronic heart failure model demonstrate that the CorInnova device:


  1. Is deployed minimally invasively through a small tube via a sub-xiphoid incision in a sheep (equivalent to a mini-thoracotomy through left ribcage in human)

  2. Stays on the heart via intrinsic pneumatic attachment and does not need to be sutured to the heart or aorta​

  3. Exhibits non-obligatory operation (when not being operated, does not significantly inhibit heart function), thereby permitting the user to turn the device on and off safely; note that LVAD operation is obligatory, lest thrombosis and stroke follow re-starting device

  4. Increases cardiac output during heart failure by on average 50% or more, and increases stroke work while reducing the percent of work done by the heart – demonstrating unloading

  5. Improves diastolic function by enhancing filling by increasing end diastolic volume and increasing total stroke volume

  6. Maintains natural curvature of the heart while operating, promoting normal heart motion
