An implantable medical device including a hermetic housing, at least one electronic board housed in the housing, a module for heat dissipation and shock absorption, housed in the housing and arranged between the electronic board and an internal wall of the housing, the module having a first layer of thermal paste placed in the internal space of the housing and deposited on the electronic board, a second, metal layer of high thermal conductivity deposited on the first layer, a third layer of thermal paste deposited on the second layer and positioned so as to come into contact with the internal wall of the housing, the third layer having a structure with a plurality of cavities distributed over the entire area of contact of the third layer with the internal wall of the housing.

Implantable medical device having an improved architecture

The main object of the invention is an implantable device of the neural interface type for processing signals, including:

Implantable device of the neural interface type and associated method

A transcranial securing device for deep brain stimulation leads comprising: a principal part for securing inside an opening formed in the cranium of a patient; and at least one first securing part housed inside said principal part; said or each securing part comprises at least one axial bore adapted to allow the passage of one or more deep brain stimulation leads; said or at least one securing part is arranged so as to be capable of passing from a first position in which the lead or leads can slide axially in the respective bores, to a second position in which it grips the lead or leads in the respective bore or bores, preventing said sliding.

Transcranial securing device for deep brain stimulation leads

A method for pumping through an orifice of a first substrate, a first volume of liquid in contact with a first hydrophobic surface of said substrate, wherein a pressure variation between the first volume of liquid and a second volume of liquid, located in contact with said orifice and a second hydrophobic surface of said substrate, is achieved by electrowetting.

Electrowetting pumping device and application to electric activity measurements

The invention relates to a method for pumping through an orifice () of a first substrate (), a first volume of liquid () in contact with a first hydrophobic surface of said substrate, wherein a pressure variation between the first volume of liquid and a second volume of liquid ('), located in contact with said orifice and a second hydrophobic surface of said substrate, is achieved by electrowetting.

Electrowetting pumping device and use for measuring electrical activity

A lead for deep electrical neurostimulation comprising a rod of biocompatible material and a blade, also of biocompatible material, secured to one end of the rod and in alignment therewith. The blade presents two main faces and a plurality of electrodes disposed on at least one of the two main faces in a two-dimensional configuration. The electrodes are connected to conductor elements disposed inside or on a surface of said rod. A deep electrical neurostimulation system comprising an electrical pulse generator connected to at least one lead of the above-described type is also disclosed.

Multiple electrode lead and a system for deep electrical neurostimulation including such a lead

Probe () for deep electrical neurostimulation, and more specifically for deep brain electrostimulation, comprising:

Probe with multiple arms and system for deep electrical neurostimulation comprising such a probe

A lead for deep brain electrical stimulation, to be inserted into liquid cavities, such as ventricles, or cysternae or subarachnoidal spaces, 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 patient's body in order to reach a region for stimulation; electrodes disposed close to a distal end of the tubular body; and a rigid stylet for inserting removably into the lumen of said tubular body; the lead being 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, and that is sufficiently flexible and elastic to follow the shape of said stylet by deforming reversibly when the stylet is inserted into the lumen. A deep electrical neurostimulation system comprising an electrical pulse generator and at least one such lead having its electrodes electrically connected to said generator.
