Abstract:
A pacing lead for pacing a patient's heart, said lead comprising:a distal end and a proximal end, and a lead body extending therebetween;a ventricular electrode positioned at about said distal end, and a ventricular conductor extending within said lead body from said proximal end to said ventricular electrode; andfixation means for fixing a portion of said lead with respect to the patient's superior vena cava, positioned on said lead at about 12 cm to 19 cm from said distal end, so that when said distal end is positioned in the patient's right ventricular apex said fixation means is positioned in said superior vena cava; wherein said fixation means comprises an extendable conductor coil forming a fixation loop which extends substantially laterally to said lead body, whereby said loop contacts the inside wall of said superior vena cava, wherein said fixation means further comprises manipulation means at said proximal end, for extending and retractsn said extendable coil:wherein said lead has an opening in said lead body, and said extendable coil comes out of said opening, the end of said coil being secured to said lead body near said opening, whereby when said coil is extended into said lead body from said proximal end, it opens into a lateral fixation loop for engaging the superior vena cava, and when said coil is retracted, said loop is withdrawn around said lead body.
