Abstract: A lead assembly comprising: a plurality of conductors; a spline comprising: a plurality of projections disposed around an outer perimeter of a spline body and extending radially away from an outer surface of the spline body, wherein each projection of the one or more projections comprises two or more projection segments separated by one or more longitudinal gaps, wherein the plurality of projections define a plurality of conductor channels around the outer perimeter of the spline body, wherein each conductor of the plurality of conductors is disposed within a respective conductor channel of the plurality of conductor channels; a plurality of electrical contacts electrically coupled to respective conductors of the plurality of conductors at the conductor first end; and an outer lead body disposed radially outwards from at least a portion of the spline body and at least a portion of each conductor of the plurality of conductors.

Abstract: In one example, a lead comprises a plurality of conductors, each conductor of the plurality of conductors comprising a conductor first end, a conductor second end, and a conductor intermediate portion therebetween, and a spline. The lead may include a first set of contacts and a second set of contracts electrically coupled with respective conductors of the plurality of conductors. The second set of contacts may include a plurality of inserts defining a plurality of apertures through which an end of respective conductors is disposed. Tire lead may further include an outer lead body disposed over at least the intermediate portion of the plurality of conductors.

Abstract: Implantable medical leads include at least one of a polymeric stylet tube and/or a distal backfill material that is softer than is conventional at least in the area where a stylet bend will cause a distal bend in the lead. The polymeric stylet tube provides for improved torsional and column stiffness during insertion while the softer distal backfill material reduces a whipping action to increase the steerability and control of the lead during insertion. The softer backfill material may be provided alone or in combination with a harder distal backfill material. The softer backfill material may be provided as an insert that is encapsulated by the harder distal back fill material or may be provided as a backfill material that exists in a position adjacent to the harder backfill material.

Abstract: A electrical contact for coupling a contact of a medical lead with electronics of a medical device including a contact member having a ring shaped wall defined by a ring inner diameter and ring outer diameter, a housing having a ring shape defining an opening therein, the opening configured to receive the medical lead therein, wherein the housing is defined in part by a housing longitudinal axis and a housing inner diameter, the contact member having at least one deflectable finger extending from the ring shaped wall into a contact opening defined by the ring inner diameter of the ring shaped wall, wherein the finger extends to a distal end and has side edges, the side edges of the finger disposed at respective angles relative to the housing longitudinal axis.
