  • Fiber bragg grating multi-point pressure sensing guidewire with birefringent component
    Patent number: 11291376
    Abstract: A system and method are presented for detecting and measuring pressure within a region of a body lumen or vessel. The pressure sensing system includes a light source for transmitting light through a pathway containing polarization-maintaining fiber optic wires. A distal portion of the polarization-maintaining fiber optic wire, which is engaged to and extends along a guidewire, includes pressure sensing station(s) made up of fiber Bragg gratings (FBG). The light transmitted to and reflected from the FBGs on the two polarization modes of the polarization-maintaining fiber optic wire can be analyzed to provide one or more pressure values.
    Type: Grant
    Filed: November 21, 2019
    Date of Patent: April 5, 2022
    Assignee: Lake Region Manufacturing, Inc.
