1. An implantable medical device system comprising an implantable electronic device having a first plurality of electrical connectors and an associated electrical lead having a second plurality of electrical connectors engagable with said first plurality of electrical connectors, wherein:

  • said lead comprises an elongated lead body having proximal and distal ends and having a connector assembly mounted to the proximal end of said lead body and having said second plurality of electrical connectors mounted along said connector assembly, said connector assembly further comprising a first mechanical connector; and

    said device is provided with a connector block having a bore extending therethrough from a proximal opening to a distal opening, sized to receive said connector assembly and having said first plurality of electrical connectors located along said bore such that on full insertion of said connector assembly into said connector block through the distal opening of the bore of said connector block, said second plurality of connectors engage said first plurality of connectors; and

    wherein said system further comprises;

    pulling tool means for pulling said connector assembly proximally in said bore of said connector block from a first position in which said connector assembly is not fully inserted in said connector block to a second position in which said connector assembly is fully inserted in the bore of said connector block, said pulling tool means having a second mechanical connector at a distal end thereof engagable with said first mechanical connector and an elongated member sized for insertion into the proximal opening of the bore of said connector block and extending proximally from said second mechanical connector for a length sufficient length to extend proximally out of the proximal opening of the bore of said connector block when said connector assembly is in said first position and said second mechanical connector is engaged with said first mechanical connector;

    wherebysaid elongated member may be grasped and pulled proximally to pull said connector assembly from said first position to said second position.
