Method for manufacturing header for implantable pulse generator, involves forming subassembly by inserting spring contact rings and ring seals into bore of header casing such that contact ring is separated from adjacent contact ring by seal

The method involves forming a subassembly by inserting a set of spring contact rings (10) and a set of ring seals into a bore (18) of a header casing such that the spring contact rings are separated from an adjacent spring contact ring by a ring seal and by inserting a spring clip and legs into a groove from an outer side of the header casing such that the legs engage opposing walls (14) of the groove and a raised flange of a bushing to secure the spring contact rings and the ring seals in a position in which adjacent spring contact rings and ring seals are in contact with each other. An independent claim is also included for a header comprising a header casing. L'invention concerne une embase (120) pour générateur d'impulsions implantable. Ladite embase (120) comprend un boîtier (124), des bagues de contact par ressort (10), des garnitures d'étanchéité de bague (40) et un raccord de réduction (61). Application : procédé de production d'une embase perfectionnée.
