Abstract
The invention is a system comprising a guidewire having expanded imaging capabilities and a processor for processing the image data and causing relevant information, such as flow, to be displayed. The system is configured to cause image data to be processed and reconfigured in a user friendly format, e.g., color-coded, to provide details of flow and device placement within a biological lumen.
Claims17
A system for measuring and displaying a characteristic of a biological lumen, comprising a sensing guidewire, a processor, memory, and a display, operatively connected together, wherein:
- the sensing guidewire comprises
- a first optical fiber comprising a first blazed Bragg grating, the grating being at least partially reflective of a first wavelength, and
- a photoabsorptive member that absorbs the first wavelength and is in photocommunication with the first blazed Bragg grating;
- and
- the memory comprises instructions that when executed cause the processor to receive data corresponding to a luminal measurement taken with the sensing guidewire and cause the display to display an image of the lumen with the luminal measurement represented in the image.
