Electrode devices with resistive elements
First Claim
1. Apparatus for applying current to a nerve, the apparatus comprising:
- a housing, which is configured to be placed around the nerve;
a plurality of electrodes, which are coupled to the housing at respective longitudinal sites along the housing, and which comprise a plurality of anodes and a cathode, wherein the plurality of anodes comprises at least two anodes disposed on a first longitudinal side of the cathode, and at least one anode disposed on a second longitudinal side of the cathode;
a control unit, which is configured to drive the anodes to apply respective anodal currents to the nerve, and the cathode to apply a cathodic current to the nerve;
an electrical lead, which couples the control unit to the electrodes; and
a set of resistors, which electrically link the electrical lead to respective ones of the electrodes, and which are disposed outside of the control unit.

Abstract
Apparatus is provided for applying current to a nerve. A cathode is adapted to be placed in a vicinity of a cathodic longitudinal site of the nerve and to apply a cathodic current to the nerve. A primary inhibiting anode is adapted to be placed in a vicinity of a primary anodal longitudinal site of the nerve and to apply a primary anodal current to the nerve. A secondary inhibiting anode is adapted to be placed in a vicinity of a secondary anodal longitudinal site of the nerve and to apply a secondary anodal current to the nerve, the secondary anodal longitudinal site being closer to the primary anodal longitudinal site than to the cathodic longitudinal site.

5. Apparatus for applying current to a nerve, the apparatus comprising:
-
a housing, which is configured to be placed around the nerve; a plurality of electrodes, which are coupled to the housing at respective longitudinal sites along the housing, and which comprise a cathode, a secondary anode, and a primary anode disposed longitudinally between the cathode and the secondary anode, a control unit, which is configured to drive the primary and secondary anodes to apply respective anodal currents to the nerve, and the cathode to apply a cathodic current to the nerve; an electrical lead, which couples the control unit to the electrodes; and a set of resistors, which electrically link the electrical lead to respective ones of the electrodes, and which are disposed outside of the control unit, wherein a first one of the resistors is coupled between the control unit and the primary anode, and a second one of the resistors is coupled between the control unit and the secondary anode, and wherein the second one of the resistors has a greater resistance than that of the first one of the resistors. - View Dependent Claims (6)
