1. A method of assembling an external trial stimulator, comprising:
- disposing a first circuit board in a cavity of a central housing frame;
connecting one or more second circuit boards to the first circuit board so that mechanical stress on the one or more second circuit boards is isolated from the first circuit board;
connecting each of the one or more second circuit boards to a corresponding shielded housing, wherein contacts in each shielded housing are soldered to contacts on the connected second circuit board;
positioning each shielded housing within a port of the central housing frame; and
connecting the central housing frame between a first housing cover and a second housing cover.

Abstract
An improved external trial stimulator provides neurostimulation functionality for implanted medical electrodes prior to implantation of an implantable neurostimulator. The external trial stimulator is housed in a four-part housing that provides mechanical and electrostatic discharge protection for the electronics mounted in a central frame of the housing. Connectors attached to leads from the electrodes connect to contacts that are recessed in the housing through ports that are centered for easy access. Multiple indicators provide information to users of the external trial stimulator.

10. An external trial stimulator, comprising:
-
a central housing frame that forms a cavity within which a first circuit board is positioned, the central housing frame comprising one or more ports; one or more shielded housings, wherein each shielded housing is positioned within one of the one or more ports and contains a second circuit board, wherein each second circuit board comprises a plurality of contacts that are soldered to contacts on the shielded housing that contains the second circuit board, and wherein each second circuit board is connected to the first circuit board so that mechanical stress on the second circuit board is isolated from the first circuit board; and first and second housing covers, wherein the central housing frame is positioned between the first and second housing covers. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
