Patent ID: 7945336

Claim:
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 ).
