Abstract
The present invention provides a pacing system with a lead having a fixation element for providing stable fixation relative to the junction of the left and right brachiocephalic veins of the patient. In a first embodiment, a short tine element is provided for engaging the brachiocephalic junction. The present invention also provides a pacing system with a lead having a fixation element for providing stable fixation relative to the atrium and the SVC of the patient. In another embodiment, a three-pronged tine is provided for engaging the portion of the atrium adjacent the SVC.
Claims15
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;
- and
- fixation means for substantially fixing a portion of said lead with respect to the junction of the left and right brachiocephalic veins when said distal end is at about the patient's ventricular apex and said lead is positioned to extend proximally from said junction through a portion of the patient's left brachiocephalic vein, wherein said fixation means comprises a short tine element extending from said lead body at an angle substantially corresponding to the angle of said junction.
A pacing lead for pacing a Datient'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;
- and
- fixation means for substantially fixing a portion of said lead with respect to the junction of the atrium and the superior vena cava when said distal end is at about the patient's ventricular apex and said lead is positioned to extend proximally from said junction through a portion of the patient's left brachycephalic vein, wherein said fixation means comprises a three-pronged tine.
A system for pacing a patient's heart, comprising:
- a pacemaker;
- and
- a lead connectable therewith 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;
- and
- fixation means for substantially fixing a portion of said lead with respect to the junction of the left and right brachiocephalic veins when said distal end is at about the patient's ventricular apex and said lead is positioned to extend proximally from said junction through a portion of the patient's left brachiocephalic vein, wherein said fixation means comprises a short tine element extending from said lead body at an angle substantially corresponding to the angle of said junction.
A system for pacing a patient's heart, comprising:
- a pacemaker;
- and
- a lead connectable therewith comprising:
- a distal end and a proximal ends 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;
- and
- fixation means for substantially fixing a portion of said lead with respect to the function of the atrium and the superior vena cava when said distal end is at about the patient's ventricular apex and said lead is positioned to extend proximally from said junction through a portion of the patient's left brachycephalic vein, wherein said fixation means comprises a three-pronged tine.
