Medical probe e.g. deep electric neurostimulation probe, for acquiring or delivering signals inside patient's body, has planar substrate placed inside of probe body and provided with orientation perpendicular to longitudinal axis of probe

摘要

The probe has an elongated flexible probe body (10) introduced for a part of its length at inside of a body of a patient. A planar substrate (20) e.g. printed circuits substrate, carrying electronic circuits i.e. integrated circuits, is placed inside of the probe body, with an orientation perpendicular to the longitudinal axis of the probe. The planar substrate has a shape which adopts the transverse section of the probe body, where the transverse section of the probe body presents a round shape. The probe body has a tubular structure, and a side wall defining a hole. The probe body is made of flexible and biocompatible material silicones, siloxanes, polyurethane, PVC, benzocyclobutene (BCB) and parylene(RTM: Polyparaxylylene).
