Abstract
Leads for use with implantable medical devices may be implanted in the venous, arterial, or lymphatic networks. The diameter of a microlead may be at most equal to 1.5 French (0.5 mm), and it may include a plurality of micro-cables each including: an electrically conductive core cable for connection to one pole of a multipolar generator of an active implantable medical device, and a polymer insulation layer surrounding the core cable. At least one exposed area may be formed in the insulation layer to form a detection/stimulation electrode.
Claims20
A method of forming a lead for use with an implantable medical device, the method comprising:
- providing a plurality of microcables, each microcable comprising a core cable and an insulation layer surrounding the core cable, wherein the core cable comprises a plurality of cable strands;
- and
- forming, for each of the plurality of microcables, at least one exposed area within the insulation layer and exposing at least one bare core cable portion through the at least one exposed area;
- wherein each at least one bare core cable portion forms an electrode of the lead.
A lead for an active implantable medical device formed by a process comprising the steps of:
- providing a plurality of microcables, each microcable comprising a core cable and an insulation layer surrounding the core cable, wherein the core cable comprises a plurality of cable strands;
- and
- forming, for each of the plurality of microcables, at least one exposed area within the insulation layer and exposing at least one bare core cable portion through the at least one exposed area;
- wherein each at least one bare core cable portion forms an electrode of the lead.
