Abstract:
A catheter comprising:a flexible, elongate catheter body having a proximal end and a distal end and a substantially cylindrical outer surface, a lumen extending longitudinally from the proximal end toward the distal end, a first passage in said body intersecting said lumen and having a first opening at said outer surface at a first given longitudinal location relative to the proximal end, and a second passage intersecting said lumen at a second given location further from said proximal end and longitudinally spaced from said first given location, said second passage having a second opening at said outer surface;an electrically conductive lead extending through said lumen from the proximal end of the catheter body through said first passage and out of said first opening, a first portion of said lead extending circumferentially about the cylindrical outer surface of the catheter body, said electrically conductive lead extending from said first lead portion back into said first opening and through said lumen and said second passage and out of said second opening, a second portion of said lead extending circumferentially about the cylindrical outer surface of the catheter body and looped about itself at said second given location, said first and second lead portions each having a circumferential extent of about 360.degree.; anda first electrode comprising a first metal sleeve disposed circumferentially about said catheter body at said first given location in electrically conductive contact with said first lead portion, and a second electrode comprising a second metal sleeve disposed circumferentially about said catheter body at said second given location in electrically conductive contact with said second lead portion, each of said first and second metal sleeves having a cylindrical outer surface and being rotationally swaged onto said catheter body over said first and second lead portions, respectively, to embed each of said lead portions into the catheter body so that said cylindrical outer surface of each of the metal sleeves is substantially flush with the cylindrical outer surface of the catheter body.
