Abstract
The transmyocardial implant for establishing blood flow through the myocardium between a heart chamber and a lumen of a coronary vasculature includes a hollow rigid conduit extending between the lumen and the heart chamber. The conduit is formed of a rigid material to resist deformation in response to contraction of the myocardium and the conduit is resistant to thrombus. A tissue growth-inducing material is secured to an exterior of the conduit. The tissue growth-inducing material is positioned to discourage tissue growth over openings of the implant.
