Abstract
An implantable electrode with a fluid reservoir is described. An implantable electrode carrier has an outer surface with electrode contacts for electrically stimulating nearby neural tissue. An enlarged fluid storage reservoir within the electrode carrier stores a treatment volume of therapeutic fluid for an extended therapeutic treatment period. At least one fluid delivery port connects the fluid storage reservoir to the outer surface of the electrode carrier for delivering the therapeutic fluid from the fluid storage reservoir to the outer surface.
Claims9
An implantable device comprising:
- an implantable electrode carrier having an outer surface including a plurality of electrode contacts for electrically stimulating nearby neural tissue;
- an enlarged fluid storage reservoir within the electrode carrier and having a diameter at least one third the diameter of the electrode carrier for storing a treatment volume of therapeutic fluid for an extended therapeutic treatment period;
- and
- at least one fluid delivery port connecting the fluid storage reservoir to the outer surface of the electrode carrier for delivering the therapeutic fluid from the fluid storage reservoir to the outer surface.
