Patent ID: 7625617

Claim:
A medical use electrical lead comprising: an elongate, cylindrical body of a polymeric material, the body having a length greater than its diameter and the body having at least one electrically conductive region defining an electrically conductive surface, the region being defined by a porous polymeric material having a plurality of pores therein, the pores being coated with a coating of an electrically conductive material, the coating comprising a first layer of a metal-deposition catalyst applied to the body and at least one further layer of a conductive material comprising a metal overlying the catalyst, the coating extending through the pores, wherein the pores extend transversely to a longitudinal axis of the cylindrical body at least partly through material of the cylindrical body; and at least one electrical conductor contained in the material of the cylindrical body and extending into the at least one electrically conductive region so that the at least one conductor is in electrically conductive communication with the conductive surface of the at least one electrically conductive region through the electrically conductive material extending through the pores, and forming an electrically conductive path that forms points of contact between the conductive surface and the embedded conductor.
