Abstract: A pre-formed j-shape stylet, slideably received within a lumen of a medical electrical lead, includes a proximal end, a distal end, a substantially straight distal segment extending from the distal end, a curved intermediate segment extending from the substantially straight distal segment, a substantially straight proximal segment extending from the curved intermedia te segment toward the proximal end, and a taper zone extending within the curve d intermediate segment.

Abstract: An implantable electrode type lead assembly 10 of the flexible type which is particularly adapted for implantation in the cardiac tissue for applications such as use with a pacemaker. The lead assembly has an electrode head 40 which includes a fixation spiral for implantation into tissue. The spiral or rotation action of the electrode head 40 is controlled by means of an elongated torsionally wound electrical coil conductor 14, the coil extending through the lead from the proximal to the distal end thereof and carried within a silicone tube 24 which is co-extensive therewith, the tube having been especially treated to modify the slip characteristics of the internal diameter (ID) thereof for high efficiency torque transfer.

Abstract: A medical electrical lead having an electrode head with an internal lumen mounted to a proximal portion of the lead body and a rotatable fixation helix advanceable from the internal lumen. The helix is mounted to a rotatable shaft which is provided with a central shaft portion and circumferential shoulders proximal and distal to the central shaft portion. A seal is mounted in the lumen of the electrode head, encircling the shaft and C-shaped seal retainers are mounted in the lumen of the electrode head member proximal and distal to the seal.
