Installation tool set for producing a head part, and method for producing a head part using the installation tool set

An installation tool set for producing a head part of an implantable medical device, the head part having a head part housing manufacturable from a curable, pourable material, the head part having a blind hole-type recess, along which in coaxial arrangement and axially serial sequence, at least one electrically conductive contact ring element and an electrically insulating seal ring are joined against each other in a force-fitting manner under an axial joining force, the installation tool set comprising:

• a rod-shaped installation tool with a rod longitudinal axis and an axially extending rod surface, along which a local recess is introduced;
• a fixing body, through which a through channel having a longitudinal channel axis passes, through which the rod-shaped installation tool is passable along at least a first rod section into which an opening at least partially penetrating the fixing body opens, the opening having an opening longitudinal axis orthogonally orientated to the longitudinal channel axis, around which an internal thread is arranged within the fixing body;
• an adjusting rod with a joining contour ending at a face side that is counter-contoured with regard to the local recess in the rod-shaped installation tool, as well as a counter-thread which is engageable with the internal thread of the fixing body;
• and
• a receiving structure defining a recess into which the rod-shaped installation tool is insertable under the axial joining force,
• at least the fixing body, the at least one electrically conductive contact ring element, and the electrically insulating seal ring being arranged coaxially and in axially serial sequence along the rod-shaped installation tool.
