Abstract
A lead for an implantable medical device (IMD) includes an electrode having a plurality of brick segments that are discrete and mechanically connected to one another in a line. The brick segments are electrically conductive and electrically connected to one another. The brick segments are configured to be powered by a pulse generator of the IMD to deliver high-voltage shocks for defibrillation therapy.
Claims20
A lead for an implantable medical device (IMD) comprising:
- an electrode comprising a plurality of brick segments that are discrete and mechanically connected to one another in a line, wherein the brick segments are electrically conductive and electrically connected to one another, wherein a distal end of a first brick segment of the electrode is connected to a proximal end of a second brick segment of the electrode at a first joint, and a proximal end of the first brick segment is connected to a distal end of a third brick segment of the electrode at a second joint, the brick segments configured to be powered by a pulse generator of the IMD to deliver high-voltage shocks for defibrillation therapy;
- and wherein the distal end of the first brick segment is connected to the proximal end of the second brick segment at the first joint via a first pin, and the proximal end of the first brick segment is connected to the distal end of the third brick segment at the second joint via a second pin.
A method of producing a lead for an implantable medical device (IMD), the method comprising:
- forming an electrode by mechanically connecting a plurality of brick segments to one another in a line, wherein the brick segments are discrete, electrically conductive, and electrically connected to one another, wherein a distal end of a first brick segment of the electrode is connected to a proximal end of a second brick segment of the electrode at a first joint, and a proximal end of the first brick segment is connected to a distal end of a third brick segment of the electrode at a second joint, the brick segments configured to be powered by a pulse generator of the IMD to deliver high-voltage shocks for defibrillation therapy, wherein the distal end of the first brick segment nests within the proximal end of the second brick segment at the first joint, and wherein the first brick segment is pivotable relative to the second brick segment at the first joint.
An implantable medical device (IMD) comprising:
- a pulse generator;
- and
- a lead comprising a lead body and an electrode, the lead body mechanically and electrically connected to both the pulse generator and the electrode, and extending from the pulse generator to the electrode, the electrode comprising a plurality of brick segments that are discrete and mechanically connected to one another in a line, wherein the brick segments are electrically conductive and electrically connected to one another, wherein a distal end of a first brick segment of the electrode is connected to a proximal end of a second brick segment of the electrode at a first joint, and the distal end of the first brick segment is nested within the proximal end of the second brick segment,
- wherein the distal end of the first brick segment nests within the proximal end of the second brick segment at the first joint;
- wherein the first brick segment is pivotable relative to the second brick segment at the first joint;
- wherein the pulse generator is configured to power the brick segments of the electrode, via the lead body, to deliver high-voltage shocks for defibrillation therapy.
