Abstract
An endocardial electrode controllable to form selected contours has a flexible electrical conductor with an internal axial channel and covered with an insulating sheath. A traction element extends through the channel and is freely moveable therein and is attached to the conductor at a selected location. A portion of the traction element is guided outside of the conductor but within the insulating sheath, and the traction element projects from the channel at a proximal end of the electrode. Tension exerted on the tension element at the proximal end deforms the conductor to a selected contour dependent upon the amount of tension.
