Abstract
A cardiac patch for treatment of a mammalian heart including perfusable vessels embedded integratedly between two layers of anisotropically oriented myocardial fibers. The cardiac patch is made using a dual 3D bioprinting technique using stereolithography to form an anisotropic construct and extrusion printing to form perfusion vessels. A nutrient and oxygen containing media can be provided within the perfusion vessels for growth of cells in the cardiac patch. The technique permits larger patches to be made for the treatment of cardiac damage in both small and large mammalian hearts.
