Robotically Controlled Electrophysiology Catheter With Closed Loop Control
Patent Number: WO 2023/038682 Al
Date Filed: March 16, 2023
Country Filed In: WIPO
Product Application: Huygens™ Catheter
Description:
The embodiments include an apparatus used in combination with a computer for sensing biopotentials and electrode contact impedance. The apparatus includes a catheter in which there is a plurality of sensing electrodes, a corresponding plurality of local amplifiers, each coupled to one of the plurality of sensing electrodes, a data, control and power circuit coupled to the plurality of local amplifiers, and a photonic device bi-directionally communicating an electrical signal with the data, control and power circuit. An optical fiber optically communicated with the photonic device. The photonic device bi-directionally communicates an optical signal with the optical fiber. An optical interface device provides optical power to the optical fiber and thence to the photonic device and receives optical signals through the optical fiber from the photonic device. The optical interface device bi-directionally communicates electrical data, control, and power signal to the computer.
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.
