Multichannel stimulator for tuned stimulation
First Claim
1. A multichannel stimulator apparatus having a plurality of channels, the apparatus comprising:
- (a) host user interface means for enabling a user to select a channel from the plurality of channels, to create and display a stimulus wave signal for the selected channel and to generate a data signal specifying the channel and stimulus wave signal;
(b) master means for receiving the data signal and directing it to the specified channel as a wave building instruction signal;
(c) slave unit means associated with the channel specified and responsive to the wave building signal to generate a corresponding low power stimulus wave signal in the channel specified, said slave unit means including logic circuitry; and
(d) means coupled to the slave unit means for electrically isolating the low power stimulus wave signal from other channels and amplifying and converting it to a corresponding high fidelity current stimulus wave signal.

Abstract
A multichannel stimulator device has a host user interface circuit for enabling a user to select a channel and easily create and display a stimulus wave signal for the selected channel and generate a data signal specifiying the channel and stimulus wave signal. The stimulator also includes a master circuit for receiving the data signal and directing it to the specified channel as a wave building instruction signal. A slave circuit associated with the channel specified receives the wave building signal and responds by generating a corresponding low power stimulus wave signal in the channel specified. Then an output circuit coupled to the slave circuit electrically isolates the low power stimulus wave signal from other channels, amplifying and converting it to a corresponding high fidelity current stimulus wave signal.
