In one embodiment of the present invention, a method and system for the safe use of a tap-water iontophoresis machine is provided. The method is based on the specific treated zone by establishing several different treatment safety parameters according to which treated body zone is selected, such as the hands, feet, or armpits. The system includes a microcontroller, a voltage measuring module, current measuring module, polarity inversion module, and an optional resistance measuring module. The microcontroller adjusts the treatment based on the following: (a) the profile selected; (b) the values embedded in the microcontroller that is associated to the profile selected; and, (c) the values measured by the different modules and the time kept by the microcontroller. By simply choosing the treated zone, the device automatically adjusts these parameters to better reflect the specific particularities of that zone and establish often narrower ranges of values and increase safety and comfort for the patient.

A shield located within an implantable medical lead may be terminated in various ways at a metal connector. The shield may be terminated by various joints including butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. The shield may terminate with a physical and electrical connection to a single metal connector. The shield may terminate with a physical and electrical connection by passing between an overlapping pair of inner and outer metal connectors. The metal connectors may include features such as teeth or threads that penetrate the insulation layers of the lead. The shield may terminate with a physical and electrical connection by exiting a jacket of a lead adjacent to a metal connector and lapping onto the metal connector.
