System for electrical stimulation of nerves
First Claim
1. A system for electrical stimulation of a peroneal nerve in a thigh of a patient, comprising:
- at least one electrode configured to contact the peroneal nerve,a pulse generator for generating a pulse pattern to be forwarded to the at least one electrode, the pulse generator being equipped with a rechargeable battery for supplying the system with a source of electrical energy,a first inductive link between the pulse generator and the electrode, and comprising an antenna adapted to be mounted on the skin of the patient and configured to communicate with a counterpart in form of an implantable module having an antenna and adapted to be implanted in the thigh of the patient,an inductive charger having a first mounting feature,a second inductive link for charging the rechargeable battery in the pulse generator comprising an antenna configured to be a counterpart for the inductive charger,a single housing provided separate from the pulse generator,a mounting fixture operable to connect the single housing to the skin of the patient, the mounting fixture having a second mounting feature,a connecting boss protruding from a surface of the single housing and configured to extend into and releasable connect with either one of the first and second mounting features,wherein the antennas for the first and second inductive links are arranged in the single housing which is connectable either to the inductive charger or the skin of the patient such that only one of the first and second inductive links can be in an active coupled connection with its counterpart at a time.

Abstract
A system for treatment of gait disorders includes an external device in the form of a pulse generator (4) 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 (3) for the inductive link between the external device and the implanted device. This antenna further incorporates an additional secondary coil (24), 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 (20) on the charger, containing the primary coil (22) for the transfer of charging power.
