1. A fluid-phase electrode lead apparatus for the delivery of electrical signals to an excitable tissue comprising: a catheter, having distal and proximal ends; at least one electrode provided at the distal end of said catheter, electrically connectable to an electric signal generator; means for providing electrolytic fluid to facilitate electric conduction of an electric signal from said at least one electrode to said excitable tissue; and an internal conduit fluidically connected to means for providing vacuum to facilitate anchoring of said distal end of the catheter to said excitable tissue. 2. The apparatus as claimed in claim 1, wherein said apparatus is further provided with an internal conduit fluidically connected to means for providing vacuum to facilitate anchoring of said distal end of the catheter to said excitable tissue. 3. The apparatus as claimed in claim 2, wherein said internal conduit fluidically connected to means for providing vacuum further protrudes relative to said internal conduit through which said electrolytic fluid is provided, both conduits provided with widening rims, and wherein said electrode is positioned near the rim of said internal conduit through which said electrolytic fluid is provided. 4. The apparatus as claimed in claim 3, wherein said conduits are coaxial. 5. The apparatus as claimed in claim 3, wherein said rims are flexible. 6. The apparatus as claimed in claim 2, wherein it is further provided with a cap, said cap provided with anchoring means for anchoring said cap to said excitable tissue, said cap also provided with an inlet and an outlet, said inlet fluidically connected to said internal conduit through which said electrolytic fluid is provided and said outlet fluidically connected to said internal conduit fluidically connected to means for providing vacuum. 7. The apparatus as claimed in claim 6, wherein said anchoring means comprise two hooks.
