Abstract
A biological pacemaker and implantation catheter for restoring normal or near normal heartbeat function without a mechanical pacemaker. The biological pacemaker is provided by a bridge of implantation cells, such as nerve cells, stem cells or ganglion cells, that are introduced into an area of electrical malfunction, such as an impaired SA node or a blocked AV node. The implantation cells grow to form a conductive cell bridge around the malfunction area so that a new pathway is provided for the electrical signals responsible for triggering heart beat contractions. The implantation catheter has a central nerve cell injection needle connected to a syringe or the like via a cell injection tube, and two elongated lateral stabilizing needles. The catheter is inserted into a blood vessel in a patient's leg, arm, shoulder or the like, and advanced until the catheter's distal end is located above the malfunction area. The distal end of the catheter is bent so that the three needles are facing the malfunction area. The two stabilizing needles are advanced into the heart wall to stabilize the catheter and the nerve cell injection needle is advanced for injection of the implantation cells.
