Patent ID: 7551967

Claim:
An implantable medical lead for transmitting electrical signals between an implantable medical device and selected body tissue, the lead comprising: a lead body comprising a distal end portion, a proximal end and an electrically insulating, elongated housing connecting said distal end portion and said proximal end, the proximal end of the lead body carrying an electrical connector assembly adapted to be electrically connected to the implantable medical device and the distal end portion of the lead body carrying at least one electrode electrically coupled to a terminal contact on the connector assembly by an electrical conductor, the elongated housing comprising at least one surface susceptible during use of the lead to the accumulation of electrostatic charges due to the electrical conductor riding in contact with the elongated housing, said at least one surface having an electrically conductive coating comprising carbon nanotubes to dissipate the accumulation of electrostatic charges; wherein said housing comprises at least one lumen extending between the distal end portion and the proximal end of the lead body, said lumen containing the electrical conductor electrically coupling the at least one electrode to the terminal contact on the connector assembly; and wherein said at least one surface comprises at least a portion of a wall defining said at least one lumen.
