Multi-contact intracerebral functional exploration probe

A multi-contact probe for intracerebral functional investigation and/or stimulation and/or treatment by radiofrequencies, comprising:

• at least one distal part of cylindrical shape comprising at least one intracerebral contact intended to be implanted in the brain of a patient,
• at least one proximal part of cylindrical shape comprising at least one connector contact intended to be connected to at least one device for recording and/or stimulation and/or treatment outside the body of the patient, and
• at least one connecting part of non-cylindrical shape configured to connect the distal part and the proximal part,
• wherein one or more of the at least one distal part, the at least one proximal part, and the at least one connecting part comprises a multilayer film comprising a substrate and at least one conductive layer deposited on the substrate,
• wherein the substrate comprises at least one polymer material, the at least one conductive layer comprises at least one transmission track, at least one intracerebral contact in the distal part, at least one connector contact in the proximal part, wherein each of the at least one transmission track is connected to the at least one intracerebral contact in the distal part and the at least one connector contact in the proximal part.

A method of manufacturing a multi-contact probe for intracerebral functional investigation and/or stimulation and/or treatment by radiofrequencies, comprising:

• a) forming a multilayer film by depositing flat, on at least a part of a substrate, at least one conductive layer to form at least one intracerebral contact, at least one connector contact, and at least one transmission track, wherein each of the at least one transmission track is connected to one of the at least one intracerebral contact and one of the at least one of a connector contact;
• b) forming a cylinder that extends along a longitudinal axis from at least a first part of the multilayer film to form a distal part of a probe configured to be implanted in the brain of a patient;
• and
• c) forming a cylinder that extends along the longitudinal axis from at least a second part of the multilayer film to form a proximal part of the probe configured to be connected to at least one device for recording and/or stimulation and/or treatment outside the patient.

A multi-contact device for intracerebral functional investigation and/or stimulation and/or treatment by radiofrequencies, comprising at least one multi-contact probe for intracerebral functional investigation, and at least one device for recording and/or stimulation and/or treatment of the patient connected to the at least one probe,

• wherein the at least one probe comprises:
• at least one distal part of cylindrical shape comprising at least one intracerebral contact intended to be implanted in the brain of a patient,
• at least one proximal part of cylindrical shape comprising at least one connector contact intended to be connected to at least one device for recording and/or stimulation and/or treatment outside the body of the patient, and
• at least one connecting part of non-cylindrical shape configured to connect the distal part and the proximal part,
• wherein the at least one connecting part comprises a multilayer film comprising a substrate and at least one conductive layer deposited on the substrate,
• wherein the substrate comprises at least one polymer material, the at least one conductive layer comprises at least one transmission track, at least one intracerebral contact in the distal part, and at least one connector contact in the proximal part,
• wherein each of the at least one transmission track is connected to the at least one intracerebral contact in the distal part and the at least one connector contact in the proximal part.
