Abstract:
1. An electrical lead system adapted to be inserted within a patient's vessel, comprising: (a) an electrically conductive shaft adapted to be inserted within a patient's vessel for a positional placement at a predetermined location, said electrically conductive shaft having an axis line; and (b) at least one expandable electrode having a pair of arm members adapted to assume a first position in a pre-deployment mode of operation and a second position in a deployed mode of operation, wherein said pair of arm members are disposed in a singular plane each with respect to the other and attached by a proximal end of each said arm member to extend from opposing lateral sides of said electrically conductive shaft, each of said arm members further has a distal end separated from said proximal end thereof by an arcuately contoured length of said each arm member, wherein, in said second position in said deployed mode of operation, said distal ends of said pair of arm members of said at least one electrode are displaced one from another with respect to said axis line for expanding said arm members into radially interfering relationship with an inner wall of a patient's vessel.
