A tissue stimulating device that provides biological stimulation of tissue has a release surface adapted for arrangement adjacent to a tissue to be stimulated. An agent reservoir of the device includes an ionic agent capable of causing a stimulation if present at sufficient high extracellular concentration close to the tissue. An agent releaser is provided in the device for releasing a selected amount of the ionic agent from the agent reservoir to an outside of the release surface at a stimulation occasion for stimulating the tissue. The ionic agent will cause a temporary change in ion permeability of the tissue cell membranes and a depolarization of the tissue cells.

Tissue stimulating device and method

A medical implantable lead has a proximal end and a distal end, and a flexible flat elongate body. The elongate body includes a layer of strip conductors extending along the length of the flat elongate body, a top insulating layer, and a bottom insulating layer. The layer of strip conductors is sealingly enclosed between the top and bottom insulating layers, and at least a major portion of the flat elongate body is twisted into an elongate helical portion having a central cavity extending longitudinally of the helical portion.
