1. A lead for implantation in a venous, arterial or lymphatic network, comprising:
- a conductor adapted to be connected to a generator of an active implantable medical device;
a sheath of electrically insulating polymer material covering the conductor on its periphery and along its length; and
an electrode formed by a ring electrically connected to the conductor via a puncture through the sheath and in contact with the conductor, wherein the ring has a differential crimping profile and penetrates the sheath at a central portion of the ring, and wherein the ring is configured to form one or more areas of compression within the sheath by moving a material of the sheath away from the ring such that the areas of compression form a seal around at least a central portion of the ring.

Abstract
A method of manufacturing a detection/stimulation lead for implantation into a venous, arterial, or lymphatic network is shown and described. The method includes providing a microcable comprising a sheath of insulating material covering an electrically conductive core. The method further includes surrounding a portion of the microcable with an electrically conductive metal ring. The method also includes crimping the ring such that the thickness of the sheath is penetrated by a portion of the metal ring and such that an electrical connection is formed between the metal ring and the electrically conductive core.
