A system for treatment of gait disorders reflects, with electrical stimulation patterns fed to electrodes () arranged at the patient, on the event of heel-strike and heel-off, the events being generated by a wireless heel switch (). The pulse generator () also transfers the electrical energy needed to operate the heel switch () wirelessly. The event signal from the heel switch () is modulated in order to achieve a longer operating range.

System for electrical stimulation of nerves

A system for treatment of gait disorders includes an external device in the form of a pulse generator () with an integrated rechargeable battery and a device adapted to be implanted in the human body. The system features an external to the body placed antenna () for the inductive link between the external device and the implanted device. This antenna further incorporates an additional secondary coil (), for inductively charging the battery in the pulse generator. The fixture on the antenna for mounting the antenna on the skin of the person is reused for being received in a charger fixture () on the charger, containing the primary coil () for the transfer of charging power.

In a system for stimulation of nerves comprising implanted electrodes, an external to the system trigger device is equipped with a sensor and a transmitter for wirelessly broadcasting a signal to be received by a pulse generator for generating a pulse pattern to be forwarded to the at least one electrode implanted in the corpus of the living being. Further the trigger device is equipped with means for detecting if the patient is walking or just standing pulling the weight from one leg to another and can thus determine if a stimulation sequence has to be performed.
