The distal-end assembly is coupled to the shaft and includes multiple splines. At least one spline includes one or more electrodes and at least one strainrelief element that is configured, when the distal-end assembly is extended in the organ, to allow the spline to 10 conform to a surface of the organ so as to make contact between the electrodes and the surface.114 Q) o CN C\j co CN cz C\l N LL N C\4 00 CN CO co
