Patent Images
1. A lead extension for providing intermediate electrical connection between an implantable pulse generator and one or more stimulation leads, comprising:
- a lead body;
a plurality of conductors disposed within the lead body;
a plurality of terminal contacts on a proximal end of the lead body, wherein the plurality of terminal contacts are electrically coupled to the plurality of conductors; and
a housing structure disposed at a distal end of the lead body, the housing structure enclosing a plurality of electrical connectors for making electrical contact with terminal contacts of a stimulation lead, wherein the plurality of electrical connectors are electrically coupled to the plurality of conductors;
the housing structure comprising an outer body of a first material and an inner reinforcing structure of a second material, wherein the first material is a relatively pliable biocompatible polymer material and the second material is a relatively rigid material; and
the reinforcing structure including a U-shaped elongated body with a plurality of pair of holes along each side of the elongated body, the reinforcing structure for receiving therein a plurality of seals with each of the plurality of seals positioned intermediate one of a corresponding pair of holes of the U-shaped elongated body of the reinforcing structure.
