Catheter For Cardiac And Renal Nerve Sensing And Mediation
Patent Number: US 2022/0047202 A1
Date Filed: February 17, 2022
Country Filed In: USA
Product Application: Huygens™ Catheter
Description:
An electrophysiology catheter includes: a catheter with a movable catheter tip; electrodes provided on or in an electrode region in a most distal portion of the catheter tip; sensing and amplification circuitry communicated with the electrodes, the sensing and amplification circuitry communicated with digitizing circuitry disposed in a circuitry region in a least distal portion of the catheter tip for locally sensing tissue-based electrophysiological signals and for bidirectionally communicating digital data signals to and from the circuitry; a flexible bending region of the catheter tip between the most and least distal portions of the catheter tip; a flexible sheath communicated to the sensing and amplification circuitry and digitizing circuitry for transmission of signals thereon; and a handle communicated with the sheath for bidirectionally communicating signals through the sheath between the catheter tip and external mapping station, and for controlling movement of the catheter tip.
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.
