A device and method for re-vascularizing my-ocardial tissue of the heart using a stent (8) are pro-vided. Multiple stents (8) are implanted into an area of hibernating myocardial tissue to permit blood to flow from the left ventricle directly into the tissue for re-vascularization. Various stent (8) embodiments are disclosed that simultaneously pierce and penetrate the tissue during delivery, and that are configured to re-sist migration out of the tissue once implanted. Alter-natively, the stent (8) may be inserted into myocardial tissue over a piercing delivery device (104). The stents are preferably delivered through a steerable catheter (46) percutaneously inserted into the left ventricle, and con-figured to hold multiple stents (8). The stents (8) are pushed from the catheter directly into the myocardium sequentially.
