Abstract
The present invention is a body implantable medical lead and method for constructing the lead. The lead has at least one electrode located along the lead body that is recessed from the outer surface of the lead body. The recessed electrode helps to prevent contact between the electrode and electrodes on a different lead when the different leads are brought into contact with each other.
Claims61
A body implantable lead comprising:
- a lead body having a central axis, proximal and distal ends and a lead body outer surface, the lead body having at least one notch formed in the outer surface of the lead body;
- at least one electrically conductive solid electrode spaced along the distal end of the lead body, each of the electrodes having an outer electrode surface, the outer surface of the electrode being located in a notch and recessed from the lead body outer surface, the electrode having a thickness;
- at least one contact located at the proximal end of the lead body;
- and
- at least one conductor connecting a respective one of the electrodes to a respective one of the contacts.

A body implantable lead comprising:
- a lead body having a central axis, proximal and distal ends and a lead body outer surface, the lead body having at least one recessed portion located at the distal end of the lead body, the lead body having at least one notch formed in the outer surface of the lead body;
- at least one electrically conductive substantially annular solid electrode spaced along the distal end of the lead body, each of the electrodes having a thickness, each of the electrodes having an outer electrode surface, the outer surface of the electrode being located in a notch and recessed from the lead body outer surface;
- means for providing electrical potential to at least one of the electrodes;
- wherein the recessed portion in the lead body has a recess depth from the lead body outer surface that is greater than the thickness of the electrode, the electrode being located in the recessed portion;
- whereby the electrode is recessed from the lead body outer surface.

A body implantable lead comprising:
- a lead body having proximal and distal ends and a lead body outer surface;
- at least one electrically conductive substantially annular electrode spaced along the distal end of the lead body, each of the electrodes having an outer electrode surface and a discontinuity through a portion of each of the electrodes the discontinuity forming opposed surfaces on each of the electrodes at opposite ends of the discontinuity, the opposing surfaces of the electrodes abutting and being securely fixed to one another, the outer surface of the electrode being recessed from the lead body outer surface;
- at least one contact located at the proximal end of the lead body;
- and
- at least one conductor connecting a respective one of the electrodes to a respective one of the contacts.

- at least one electrically conductive substantially annular solid electrode spaced along the distal end of the lead body, each of the electrodes having a thickness, each of the electrodes having an outer electrode surface, the outer surface of the electrode being located in a notch and recessed from the lead body outer surface;
- at least one contact located at the proximal end of the lead body;
- and
- at least one conductor connecting a respective one of the electrodes to a respective one of the contacts
- wherein the recessed portion in the lead body has a recess depth from the lead body outer surface that is greater than the thickness of the electrode, the electrode being located in the recessed portion;
- whereby the electrode is recessed from the lead body outer surface.
