A fluid delivery system and a propellant therefor. The propellant comprises a mixture of a plurality of substances, the precise by-weight or by-molar combination of which is used to set the propellant pressure within a desirable pressure range. At least one of the plurality of propellant substances is a relatively higher vapor pressure fluid; and at least one of the plurality of propellant substances is a relatively lower vapor pressure fluid.

Fluid delivery system and propellant mixture therefor

A method of fabricating a stimulation electrode for use on an implantable lead, the lead and electrode so fabricated and a method of their use. The electrode is made by coating a conductive electrode member with a coating of a high surface area coating having micron or sub-micron surface features and after coating, plasma cleaning the electrode member. The electrode is coupled to an insulated conductor of an implantable lead and is employed to stimulate body tissue. The high surface area coating may be platinum black, ruthenium oxide, another metal oxide, a metal nitride or the like. Steroid may be applied to the electrode member after coating.

Method for tissue stimulation and fabrication of low polarization implantable stimulation electrode

A process for producing a medical electrode. A coil of conductive metal is slid over a tubular insulative substrate. The spaces between individual turns of the coil are backfilled with an insulative plastic. The backfilled plastic is thereafter etched away from and off of the exterior of the metal coil by means of a gas plasma.
