The Use Of Local Amplifiers And A Huygens Sensor Array In Measuring Bioelectrical Signals And Clinical Applications Thereof
Patent Number: WO 2023/038748 A1
Date Filed: March 16, 2023
Country Filed In: WIPO
Product Application: Huygens™ Catheter
Description:
With respect to the methodology of using the Huygens sensing array, the invention includes an improvement in a method of sensing biopotentials in tissue including the steps of: providing a Huygens sensor array; and sensing a native electrical biopotential signal using at least one electrode on a catheter with an amplifier circuit placed on the inner surface of the at least one electrode in the Huygens sensor array to generate a well-formed waveform of the biopotential showing clear electrical properties indicative of the tissue with a SFDR of at least 24.9 dB and SNR of at least -13 dB. In one embodiment the tissue is cardiac tissue and the biopotential signal sensed by the Huygens sensing array is a native cardiac waveform. In one embodiment the sensed biopotential signal is a manifestation of underlying electrochemical activity sensed by the Huygens sensing array of a biological substrate corresponding to the tissue.
Field of Use: The Huygens™ Catheter represents a major advancement in creating a next-generation endocardial-mapping catheter for the electrophysiology arena. Based on the earlier discoveries made with the MOSFET™ Catheter, the Huygens£ Catheter employs the same basic concept of moving all the bioelectric signal measurement, amplification, filtering and data-processing onto a flexible micro-circuit board at the distal end of the catheter in order to mitigate the noise pollution issues associated with current mapping catheter systems. The Huygens™ Catheter provide a wholly new approach to catheter electrode placement and fidelity that allows for the ability to accurately measure extremely small millivolt signals which helps in increasing signal capture and resolution by 200x. Huygens™ also provides real analog to digital signal conversion at the sensor tip to eliminate signal degradation as information is sent to the external mapping station.
