Optically Coupled Catheter And Method Of Using The Same
Patent Number: US 11,540,775 B2
Date Filed: January 3, 2023
Country Filed In: USA
Product Application: Optical Catheter
Description:
The embodiments include an apparatus used in combination with a computer for sensing biopotentials. 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 bidirectionally communicating an electrical signal with the data, control and power circuit. An optical fiber optically communicated with the photonic device. The photonic device bidirectionally 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 bidirectionally communicates an electrical data, control and power signal to the computer.
Field of Use: The Optical Cather was designed to provided physicians doing catheter-based imaging and mapping a better tool to enable higher resolution imaging. In addition, the catheter tip has a biosensor that allows for area biopotentials to be measured accurately and for the data to be transmitted instantly to the physician.
