1. An implantable stimulator, comprising:
- a housing;
a first plastic component comprising a polymeric material;
a second plastic component comprising a polymeric material, wherein the implantable stimulator comprises a polymer-polymer interface comprising a direct polymer-to-polymer bond between portions of the first and second plastic components;
a light absorbing metal layer disposed over at least a portion of the polymer-polymer interface, wherein the direct polymer-to-polymer bond comprises a region in which the first and second plastic components of the implantable stimulator are in direct contact with each other and directly bonded without the light absorbing metal layer between the first and second plastic components; and
an electronic subassembly disposed within the housing.

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.
