Abstract
A catheter has a flexible, elongate, substantially cylindrical catheter body with at least one lumen extending from the proximal end toward the distal end. One or more radial passages intersect the lumen from the outer surface of the catheter body. A conductive lead is threaded through the lumen and passage to the outer surface of the catheter where it is circumferentially wrapped about the catheter to form a lead portion. A metal sleeve electrode is rotationally swaged over the lead portion in electrically conductive contact with the lead portion. A plurality of lead portions may be formed circumferentially about a catheter body by threading the conductive lead out of a passage around the catheter and back into the passage and lumen to another passage where another lead portion is formed.
