Cardiac or cerebral vessel microlead with electrode ring
First Claim
1. A method of manufacturing a detection/stimulation lead for implantation into a venous, arterial, or lymphatic network, comprising:
- providing a microcable comprising a sheath of insulating material covering an electrically conductive core;
surrounding a portion of the microcable with an electrically conductive metal ring;
crimping the ring to achieve a differential crimping profile wherein the inner diameter of at least a central longitudinal portion of the conductive metal ring is smaller than the inner diameter of the longitudinal end portions on either side of the central portion, and 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 without removing insulating material at the penetration location; and
while crimping the ring, pushing insulating material beneath the metal ring to areas adjacent the edges of the metal ring to provide a seal.

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.
