Abstract:
Systems, apparatus, and methods are disclosed for bi-directionally conveying biomedical signals between a patient and signal acquisition and processing devices. An electrophysiology (EP) system includes an analog input protection and filtering stage with a differential circuit to process the biomedical signals to and from the patient; a signal amplification stage with a differential amplifier circuit to amplify an output of the differential circuit; an analog-to-digital converter stage to digitize an output of the differential amplifier circuit; a communication module to interface between the analog-to-digital converter stage and a digital processing stage having a plurality of signal modules; at least one processor to execute the plurality of signal modules, applying frequency-selective filtering and signal processing algorithms to the output from the analog-to-digital converter stage, to extract high-frequency and low-amplitude features of the biomedical signals in frequency ranges of interest; and a display for pattern- and time-aligned visualization of the biomedical signals.

Claim (Index 19):
A system for visualization of one or more biomedical signals emitted from a patient, the system comprising:\n a biomedical signal interface device for conveying the one or more biomedical signals to the system, comprising:\n an input protection circuit to shunt a defibrillation signal; \n a plurality of circuit board elements coupled to the input protection circuit, each of the plurality of circuit board elements comprising:\n a differential circuit having two paths configured to process the one or more biomedical signals in an analog domain, wherein the differential circuit is further configured to linearly attenuate a respective amplitude of the one or more biomedical signals within a first frequency range between about 350 kHz and about 600 kHz; \n a differential amplifier module comprising a plurality of differential amplifier stages, wherein the differential amplifier module is coupled to each of the two paths of the differential circuit and is configured to amplify a first output of the differential circuit by an amplification factor, wherein the amplification factor is less than or equal to about 50 for the one or more biomedical signals within a second frequency range between about 0.01 Hz and about 1000 Hz; and \n an analog-to-digital converter module, coupled to the differential amplifier module, configured to digitize a second output of the differential amplifier module to produce a digitized third output of the analog-to-digital converter module, wherein the analog-to-digital converter module has greater than 16-bit resolution; and \n \n a processor comprising software, communicatively coupled to each analog-to-digital converter module of the plurality of circuit board elements, wherein the processor is configured to process the respective digitized third output from each analog-to-digital converter module for display.
