Patent ID: 7894912

Claim:
A lead for deep brain electrical stimulation, 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 patients body in order to reach a region for stimulation; a plurality of electrodes carried by said tubular body and capable of being brought into contact with said region for stimulation within the body of said patient; and a rigid stylet for inserting removably into the lumen of said tubular body by a proximal end of said tubular body, which is opposed to a distal end of the tubular body; 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 which separates the proximal and the distal end of said tubular body, which are not aligned with each other; said tubular body being made of a biocompatible material which is sufficiently flexible and elastic to straighten by following the shape of said stylet by deforming reversibly when the stylet is inserted into the lumen, and to recover its non-rectilinear equilibrium shape after extraction of said stylet; and said electrodes being carried by a distal part of the tubular body, close to said distal end.
