Abstract
An implantable stimulator that includes a housing, a first plastic component, and a second plastic component, where the first and second plastic components form a polymer-polymer interface. A light absorbing metal layer is disposed over at least a portion of the interface and an electronic subassembly is disposed within the housing. The first and second plastic components can be welded together by irradiating the light absorbing metal layer which converts the light to heat.
