A microlead includes exposed areas forming stimulation electrodes. The microlead further includes a stimulation zone (ZS) defined by a first preshape of the microcable at the distal end thereof, in a region including the electrodes (30). The microlead further includes a retention zone (ZR) including a retainer shape adapted to abut the wall of the target vessel. The microlead further includes a stretching zone (ZEL) proximal to the retention zone. The stretching zone may be defined by a shape adapted to make the region elastically deformable in the longitudinal direction under the effect of an axial traction/compression stress. The axial traction/compression stiffness in the elongation zone is lower than that in the retention and stimulation areas. |
