Abstract
In am method for coating a tip region of an multipolar electrode head adapted to be mounted at a distal end of a lead used preferably for providing heart stimulation by means of a heart stimulation apparatus, an electrode head is provided having a tip with a ceramic part in which a number of small spaced-apart conductive electrode surfaces are disposed, a region of the electrode head tip is directly coated with a tissue compatible material, such as TiN, so that all conductive electrode surfaces are coated in a single step coating operation without any masking operation.
Claims7
A method for coating a tip region of a multipolar electrode head adapted for mounting at a distal end of a medical stimulation lead, comprising the steps of:
- providing an electrode head having a tip with a non-conducting part having a plurality of spaced-apart conductive electrode surfaces;
- and
- directly coating an unmasked region of said tip with a tissue compatible material to simultaneously coat all of said conductive electrode surfaces.
A method for manufacturing a multipolar electrode head adapted for mounting at a distal end of a medical stimulation lead, comprising the steps of:
- providing a non-conducting part with a plurality of recesses therein;
- inserting electrically conductive wires respectively in said recesses;
- forming a plurality of conductive electrode surfaces respectively at said conductive wires on a surface of said non-conducting part, so that said conductive electrode surfaces are spaced apart from each other on said surface of said non-conducting part;
- and
- directly coating at least an unmasked portion of said surface of said non-conducting part with a tissue compatible material to simultaneously coat all of said electrode surfaces.
