Abstract
A low-polarization electrode for use in medical stimulation leads. The electrode is provided with grooving and is coated with platinum black.
Claims7
An implantable lead, comprising:
- an electrical conductor having a proximal end and a distal end;
- an insulative sheath covering said conductor;
- an electrical connector coupled to the proximal end of said conductor;
- and
- an electrode means having a surface exposed through the exterior of said insulative sheath, for directly contacting the endocardium of a human heart at said exposed surface, wherein substantially all of said exposed surface is provided with a coating of platinum black and wherein said electrode means is coupled to the distal end of said conductor.
