NANO MULTIPOLE RINGS FOR MEDICAL MICROLEADS
First Claim
1. A multipolar lead for implantation in a venous, arterial, or lymphatic network, and for use with an electric stimulation or detection device, comprising:
- at least two microcables, each having a central conductor for connection to the electric stimulation or detection device; and
a first ring having at least two lumens, each sized to receive a microcable of the at least two microcables, wherein one of the at least two lumens is a connection lumen which receives a first microcable of the at least two microcables;
wherein the first ring further comprises a connection element movable into the connection lumen to pierce a sheath of the first microcable and to press into the central conductor of the first microcable received by the connection lumen, electrically connecting at least a portion of the first ring to the central conductor.

4. A multipolar lead for detection/stimulation for implantation in a venous, arterial or lymphatic network, comprising:
-
at least two microcables, each comprising a full central conductor for connection to a generator of an active implantable medical device, and each having an insulating polymeric material surrounding the central conductor on its periphery and along its length; and at least one detection/stimulation electrode for electrically connecting to a central conductor of a microcable and to come against a wall of a target vessel of said venous, arterial or lymphatic network, wherein the at least one electrode comprises a cylindrical metal ring having a longitudinal connection lumen to receive a microcable and to form an electrical connection between at least one portion of the ring and the microcable, and at least one longitudinal lumen for passing the other microcable without forming an electrical connection. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
