Abstract
The present invention provides an electrode having a substrate and a conductive polymer film layer on the exposed surface, the film layer having a capacitance per area of at least 0.5 F/cm2 and/or wherein the film layer has a thickness of between 50-1000 μm. A medical device having a plurality of electrodes wherein at least one of the electrodes includes a polymer film layer, the film layer having a capacitance per area of at least 0.5 F/cm2 is also provided, as are systems including the medical device, methods of treatment of a spinal cord lesion and methods of manufacturing the electrodes.
Claims23
A medical device having a plurality of electrodes wherein at least one of the electrodes includes a polymer film layer, the film layer having a capacitance per area of at least 0.5 F/cm2.
A method of treating a spinal cord lesion in a patient, the method including the steps of:
- percutaneously implanting a plurality of electrodes to positions proximate the spinal cord of the patient and on opposing sides of the lesion;
- applying an electrical field between the electrodes to stimulate axon regrowth;
- and
- periodically reversing the polarity of the electrical field to stimulate axon regrowth from the other side of the lesion.
An electrode having a substrate and a conductive polymer film layer on the exposed surface, the film layer having a capacitance per area of at least 0.5 F/cm2.
An electrode having a substrate and a conductive polymer film layer on the exposed surface, the film layer having a thickness of between 50-1000 μm.
A method of manufacturing an electrode, the method including the steps of:
- coating a surface of a conductive substrate with a conductive polymer film layer using a solution of said conductive polymer whilst soft-baking the substrate and film layer, until the film layer reaches a thickness of at least 50 μm;
- and
- hard-baking the resulting structure.
