Abstract
A multizone epicardial pacing lead (10) having a lead body (12) with a proximal connector (14) for coupling to a generator of an active implantable medical device and, distally, an anchor to an epicardium wall and an active part comprising a plurality of stimulation electrodes, coming into contact with, or penetrating, the epicardium wall. This active part comprises a distributor housing (16) and a network of flexible microcables (18) radiating from the housing. Each microcable is formed of an electrically insulated conductor comprising at least one denuded area (20), each of these areas forming a stimulation electrode.
Claims24
An epicardial stimulation lead, comprising:
- a lead body having a proximal end, a distal end, at least one connecting conductor and a sheath made of a deformable material, said sheath enclosing said at least one connecting conductor, the proximal end having a connector for coupling said at least one connecting conductor to a generator of an active implantable medical device,
- a distributor housing disposed at the distal end of said lead body;
- means for anchoring the distal end of the lead body to a patient's epicardium wall;
- and
- an active part comprising a plurality of electrically insulated flexible microcable conductors having a proximal end, a distal end, and an insulating coating, the proximal ends being coupled to the distributor housing, the distal ends being free and remote from the distributor housing, said microcables being electrically connectable via the distributor housing to a connection conductor of the lead body, wherein:
- each microcable has a main direction extending from said distributor housing and a diameter of at most equal to 2 French (0.66 mm);
- each microcable comprises at least one denuded area in said insulating coating forming a stimulation electrode adapted to contact or penetrate an epicardium wall, the stimulation electrodes of a same microcable being electrically connected together, and
- each microcable comprises at least one transverse elongated member
- extending at an angle relative to the main direction of the microcable, and for penetrating into the wall of the epicardium, wherein said at least one elongated member is a transverse landfill loop formed by a curvature of the microcable.
