A screwless quick connection system for connecting a lead connector to a generator of an active implantable medical device is shown and described. The connector head includes a housing receiving a plug of a lead connector. A mechanism for locking the plug into the housing is provided by a U-folded leaf spring. Each branch of the U is provided with a respective hole sized so that the plug passes through the holes on both branches when it is inserted into the housing. The blade is deformable between a free state, in the absence of plug, and a deformed state, with the plug inserted therein. In the free state, both holes are misaligned, while in the deformed state they are aligned. In this way, an edge of both holes exerts by reaction a radial stress force against the smooth outer surface of the plug inserted therein.

A screwless quick connection system for connecting a lead connector to a generator of an active implantable medical device. The connector head includes a housing () receiving a plug () of a lead connector. A mechanism for locking the plug into the housing is provided by a U-folded leaf spring (). Each branch of the U is provided with a respective hole sized so that the plug () passes through the holes on both branches when it is inserted into the housing. The blade is deformable between a free state, in the absence of plug, and a deformed state, with the plug inserted therein. In the free state, both holes are misaligned, while in the deformed state they are aligned. In this way, an edge of both holes exerts by reaction a radial stress force against the smooth outer surface of the plug inserted therein. A pushbutton flange () unlocks the system by a support maneuver on only one side of the connector head.

A process for mechanical assembly and electrical interconnection of the functional components of an active implantable medical device. A first step involves preparing an interconnection flex circuit () that is able to be electrically and mechanically linked to an electronic circuit module (), a supply battery () and a series of feedthrough terminals () of the device, prior to being placed in a common case. The flex circuit has a series of pads () for linking to homologous metallizations () of the substrate. The mechanical assembling and electrical linking of these pads () to the metallizations () is performed without either the use of any activation flux or introduction of fusible brazing, and rather by applying an intermediate anisotropic conductive material () placed between the pads () and metallizations (), followed by polymerizing this material. The applying and polymerizing are performed under controlled conditions of pressure, temperature and duration.
