Abstract
A drug delivery catheter suited for cardiac procedures. The catheter includes a distal helical coil or other fixation and penetrating element which can be operated from the proximal end of the catheter to engage and penetrate the myocardium. Once delivered to the inside of the heart, the catheter can be used to inject small doses of therapeutic agents to the myocardium. The drug delivery system of the catheter allows for precise control of the dose injected into the heart wall.
