The left ventricle stimulation probe which is implantable into the venous coronary network to an active implantable medical device, especially the stimulation of the type 'multisite'

摘要

It is provided a probe body, comprising a hollow sheath elastically deformable and essentially free of any rigid element, whose distal end (34) supports at least one stimulation electrode (54), and a removable mandrel, which can be introduced inside the sheath of the probe body and movable in translation inside the - ci, the mandrel being relatively rigid with respect to the sheath and plastically deformable locally. The distal end (34) of the probe has in the absence of stress two curves are recorded in two distinct surfaces, with a first surface (62) corresponding to an orientation curve defined by a preform of the probe body, and a second surface (64) corresponding to a support curve defined by a bent shape, of course of the distal end (34) of the probe. According to the invention, the distal end (34) of the probe is self - to be oriented, the electrode being a sectoral electrode, with an active part of the lateral (54) extending in a radial plane, only over a sector of the probe body. Preferably, this active portion is turned in a direction substantially perpendicular to the plane formed by the elbow (64) of the distal end of the probe body.
