ABSTRACT:
An implantable stimulation lead having an anti-inflammatory coating on the exposed surface area of the distal tip electrode. The coating is a semi-viscous or gelatinous material having the ability to absorb physiological fluids to provide electrical conductivity through the coating. The coating preferably has a matrix having an innate hypo-inflammatory property which can be combined with drugs and therapeutic agents to deliver the drugs and agents by co-dissolution or diffusion, or alternatively the matrix material can be used as a coating to keep the electrode surface electrochemically clean prior to and during implant.
