Patent ID: 8160710

Claim:
A stimulation lead assembly for placement in the pelvic floor and adapted to be coupled to an implantable pulse generator to deliver stimulation to selected stimulation sites comprising: a first stimulation lead comprising: a first elongated lead body extending between a first lead body proximal end and a first lead body distal end comprising a first insulating sheath and at least one electrical conductor within the first insulating sheath; a first proximal connector assembly having at least one lead connector element at the first lead body proximal end coupled to a proximal end of the electrical conductor; a first stimulation electrode at the first lead body distal end coupled to a distal end of the electrical conductor; and a first fixation mechanism extending along a portion of the lead body coupled to the first insulating sheath and extending laterally away from the lead body, the fixation mechanism formed of a material encouraging tissue ingrowth along the length of the portion of the lead body to stabilize the stimulation electrode at the stimulation site; and a second stimulation lead comprising: a second elongated lead body extending between a second lead body proximal end and a second lead body distal end comprising a second insulating sheath and at least one electrical conductor within the second insulating sheath; a second proximal connector assembly having at least one lead connector element at the second lead body proximal end coupled to a proximal end of the electrical conductor; a second stimulation electrode at the second lead body distal end coupled to a distal end of the electrical conductor; and a second fixation mechanism extending along a portion of the second lead body coupled to the second insulating sheath and extending laterally away from the second lead body, the second fixation mechanism formed of a material encouraging tissue ingrowth along the length of the portion of the second lead body to stabilize the stimulation electrode at the stimulation site; and an interconnecting portion coupled to the first and second lead body distal ends.
