First Claim
Patent Images
1. An external trial stimulator powered by one or more batteries, comprising:
- a housing, comprising;
a first cover comprising a battery compartment;
a second cover; and
a center frame, disposed between the first cover and the second cover, wherein the center frame forms a central cavity within the external trial stimulator and defines at least a portion of an exterior surface of the external trial stimulator;
wherein the first cover, second cover, and center frame comprise separate components fixed together;
a first circuit board, disposed in the cavity of the center frame, comprising neurostimulation logic programmable to generate neurostimulation pulses for electrodes implanted in a user of the external trial stimulator; and
at least one port in the center frame, wherein each at least one port is electrically connected to the first circuit board and adapted for connection to a lead for the electrodes.

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.
