Abstract
Atrial-ventricular coaxial transvenous pacing lead including an inner ventricular lead having an electrode and an outer atrial lead having an atrial sidearm lead, the atrial sidearm lead including a sigmoidal shape and an electrode at the distal end of the sidearm lead. Outwardly extending tines can surround either or both of the electrodes. The atrial sidearm lead maintains geometrical memory of the sigmoidal shape. The atrial sidearm head can be used absent the ventricular lead.
Claims15
Atrial-ventricular sidearm transvenous pacing lead for supplying stimulating signals to an atrium cavity and a ventricular cavity comprising:
- a. ventricular lead including first a space-wound coil, insulation covering said first space-wound coil, a ventricular electrode secured to a distal end of said first space-wound coil and a proximal tip secured to a proximal end;
- b. atrial lead including a second space-wound coil slideably mounted in coaxial relation over said first space-wound coil and insulation covering said second space-wound coil and a proximal tip secured to the proximal end;
- and
- c. atrial sidearm lead including a space-wound coil having a geometrical memory shape, means connecting said distal end of said sidearm lead to said distal end of said atrial lead, insulation covering said space-wound coil of said lead, and an atrial electrode affixed to a pacing tip of said atrial sidearm lead whereby said ventricle lead coaxially slides within said atrial lead for positioning of said ventricular electrode into said ventricular cavity and said atrial electrode into said atrial cavity.
Atrial-ventricular sidearm transvenous pacing lead comprising:
- a. ventricular lead including a first space-wound coil, insulation covering said first space-wound coil, ring-tip electrode secured to one end of said first space-wound coil, and a plurality of tines extending outwardly from said ring-tip electrode;
- b. atrial lead including a second space-wound coil slideably mounted in coaxial relation over said first space-wound coil and insulation covering said second space-wound coil;
- and
- c. atrial sidearm lead including a space-wound coil having a geometrical memory shape, a reverse foldback connecting said distal end of said sidearm lead to said distal end of said atrial lead, insulation covering said space-wound coil, a ring-tip electrode affixed to a pacing tip of said atrial sidearm lead, and a plurality of tines extending outwardly from said ring-tip electrode.
A body implantable lead comprising:
- a first conductor having a proximal end and having a distal end with an electrode attached thereto;
- a second conductor having a proximal end and having a distal end with an electrode attached thereto and having a point intermediate said proximal end and said distal end such that said second conductor is slideably mounted coaxially about said first conductor from said proximal end of said second conductor to said point and said second conductor is angularly displaced from said first conductor from said point to said distal end of said second conductor at an obtuse angle relative to said distal end of said first conductor and said first conductor and said second conductor are mutually insulated.
