1. A probe (1, 1′
- ) for deep electrical neurostimulation comprising;
a tubular body (10) of biocompatible material with a lateral wall (11) defining a lumen (12), said tubular body (10) being configured to be implanted, for at least a part of a length of the tubular body inside a patient'"'"'s body for reaching a region to be stimulated;
a plurality of arms (32) each bearing at least one stimulation electrode (40) and being able to pass from a first position in which they are housed inside of said tubular body (11) to a second position in which they project radially from said lateral wall (11) and inversely; and
means (20 and 50) for making said arms (32) pass from said first position to said second position and inversely;
a base element (31) of tubular shape placed inside of the lumen (12) of said tubular body (10);
wherein a plurality of said arms (32) are connected together by the base element (31), and further wherein said arms (32) and said base element (31) make up a single part (30) of strap shape, wound so as to adapt to the shape of the lumen (12) of said tubular body (10).

Abstract
Probe (1) for deep electrical neurostimulation, and more specifically for deep brain electrostimulation, comprising:
- a tubular body (10) of biocompatible material with a lateral wall (11) defining a lumen (12) and a closed anterior end (13), said tubular body (11) can be introduced for at least a part of its length inside a patient'"'"'s body for reaching a region to be stimulated;
- wherein it also comprises:
- a plurality of electrically insulating arms (32) each bearing at least one electrode (40) and being able to pass from a first position in which they are housed inside of said tubular body (11) to a second position in which they project radially from this latter and inversely; and
- means (20 and 50) for making said arms (32) pass from said first position to said second position and inversely.
