Abstract
The tip electrode member has a rounded or bullet shaped distal end and has grooves etched into the distal end to increase the surface area of the electrode member within a small displaced surface area to minimize polarization of the tip electrode member while ensuring sufficient electric current flow to cause heart muscle depolarization. Preferably, the tip electrode member is made of titanium or a titanium alloy and is coated with carbon.
