ABSTRACT:
A cardiac lead joint assembly is provided for connecting a polymeric sleeve to a tubular metallic structure, such as the tubular metallic connector that connects to the header of a cardiac stimulator. The joint assembly includes a tubular metallic member, which may be the tubular connector, an electrode, or some other structure in the lead. The tubular metallic member has an annular groove formed on the exterior surface thereof. A polymeric annular member is disposed around the tubular metallic member and is seated in the annular groove. The polymeric sleeve is disposed over a portion of the tubular metallic member and is secured to the polymeric annular member by an adhesive. The joint assembly provides a polymer-to-polymer interface for adhesive bonding.
