Patent Images
1. An implantable microstimulator, comprising:
- a plastic housing consisting essentially of plastic and having a first end and an interior surface;
an electronic subassembly disposed within the plastic housing, wherein the interior surface of the plastic housing forms, at least in part, a surface of a cavity in which the electronic subassembly is disposed; and
a conductive plastic electrode consisting essentially of conductive plastic and disposed at the first end of the plastic housing and in electrical communication with the electronic subassembly;
wherein the microstimulator forms a hermetically sealed structure with the plastic housing and conductive plastic electrode hermetically sealed together.

Abstract
An implantable microstimulator includes a plastic housing having a first end; an electronic subassembly; and a conductive plastic electrode disposed at the first end of the plastic housing and in electrical communication with the electronic subassembly. The microstimulator forms a hermetically sealed structure. Optionally, the microstimulator also includes a second electrode disposed at a second end of the plastic housing and in electrical communication with the electronic subassembly. The second electrode may also be a conductive plastic electrode.
