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 1):
A system for bi-directionally conveying biomedical signals between a patient and biomedical signal acquisition and processing devices, comprising:\n an analog input protection and filtering stage, configured to be coupled to a plurality of electrodes that conduct the biomedical signals, the analog input protection and filtering stage comprising a differential circuit with two paths configured to process the biomedical signals in an analog domain to and from the patient; a signal amplification stage comprising a differential amplifier circuit with a plurality of differential amplifier stages, wherein the differential amplifier circuit 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 of less than or equal to about 50 for the biomedical signals within a frequency range of about 0.01 Hz to about 1000 Hz; an analog-to-digital converter stage comprising an analog-to-digital converter coupled to the differential amplifier circuit and configured to digitize a second output of the differential amplifier circuit, wherein the analog-to-digital converter has greater than 16-bit resolution; a communication module, coupled to the analog-to-digital converter stage and configured to provide a digital communication interface between a digitized third output of the analog-to-digital converter stage and an input to a digital processing stage; and the digital processing stage, coupled to the communication module, comprising:\n a memory with a signal path module comprising a plurality of signal modules configured to apply filtering comprising frequency-selective filtering and signal processing algorithms to the digitized third output from the analog-to-digital converter stage to extract high-frequency and low-amplitude features of the biomedical signals; and \n at least one processor configured to execute the plurality of signal modules, wherein the at least one processor filters the biomedical signals in frequency ranges of interest.
