Patent ID: 11967969
Assignee: BOSTON SCIENTIFIC NEUROMODULATION CORPORATION
Field: Medical technology (Instruments)
Classification: CPC H  A | IPC A  H

Claim 9:
10. The pulse generator of claim 1, wherein the digital data further specifies a magnitude of a total cathodic current amplitude to be produced at the electrode nodes, wherein the first DAC is further configured to produce a third current with a magnitude indicative of the total cathodic current amplitude to be produced at the electrode nodes, wherein a polarity of the third current is opposite the first current, wherein the pulse generator further comprises:
a plurality of second calibration circuits each configured to receive the third current, wherein each of the second calibration circuits is controllable to produce a different fourth current as a function of the third current; and
a plurality of third DACs each associated with one of the electrode nodes, wherein each third DAC is configured to receive one of the fourth currents, wherein each of the third DACs is configured when selected to amplify its received fourth current to produce a cathodic stimulation current at its associated electrode node.
