A device for cooling locally, including a cooling member, a crystal having the capacity to cool via absorption of a near-infrared exciting light signal, an illuminating system intended to deliver an exciting light signal, the crystal having an elongate shape about a longitudinal axis between a near end and a far end and having a closed constant outside cross section and containing a central channel formed, from its far end, over at least some of its length, the cooling member including a rod embedded via a first end into the central channel of the crystal and including a protruding second end that forms a cooling finger.

Device for cooling locally

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.
