ACTIVE IMPLANTABLE MEDICAL DEVICE (AIMD) COMPRISING A TRANSPARENT ENCAPSULATION

摘要

The present invention concerns an active implantable medical device (AIMD) for implantation in a body of a patient, said AIMD comprising an encapsulation (1) defining an inner space sealingly separated from an outer environment by walls transparent to a given wavelength range comprised between 380 and 2200nm,wherein (a)the walls comprise a first main wall (1a) and a second main wall (1b) facing one another and separated from one another by an inner height (Hi) of the inner space, (b)the encapsulation comprises a housing formed by a first component (2) and a second component (3) both made of a single material and hermetically joined to one another along a single interface (23) to define the inner space hermetically sealed by the walls from the outer environment, (c)the inner space contains an electronic circuit including a main source of light(10L) of the given wavelength range and/or a first photodetector (10P) detecting a light of the given wavelength range,andfacing a wall of the encapsulation, wherein joining of the first component and second components (2, 3) is carried out by welding without addition of a third material, the inner space has a volume (Vi) of at least 2cm³.
