The invention relates to a device for cooling an organ locally, that includes an elongate stem including a far end intended to make contact with an organ to be cooled and comprising including a cooling element having a cold finger, a crystal that has a capacity to cool via excitation at a set excitation wavelength, said crystal being positioned adjacent to said cooling element, an optical guide that is able to convey a light signal at said excitation wavelength and that opens onto said crystal, and an illuminating system including at least one light source, which light source is arranged to emit said light signal.

A lead for deep brain electrical stimulation, to be inserted into liquid cavities, such as ventricles, or cysternae or subarachnoidal spaces, the lead comprising: a tubular body of biocompatible material having a side wall defining a lumen, said tubular body being suitable for being inserted over at least a fraction of its length into the inside of a patient's body in order to reach a region for stimulation; electrodes disposed close to a distal end of the tubular body; and a rigid stylet for inserting removably into the lumen of said tubular body; the lead being wherein said tubular body has an equilibrium shape that is not rectilinear, being different from the shape of the stylet and presenting one and only one bend, and that is sufficiently flexible and elastic to follow the shape of said stylet by deforming reversibly when the stylet is inserted into the lumen. A deep electrical neurostimulation system comprising an electrical pulse generator and at least one such lead having its electrodes electrically connected to said generator.
