The present invention is directed towards an apparatus for pressure based lumen mapping. The apparatus includes a flexible elongated member having a portion insertable into the lumen, means for measuring pressure inside the lumen, operatively connected to the insertable portion, means for moving the insertable portion in a predetermined manner, wherein pressure is measured at various points during movement, and a processor for processing pressure measurements, wherein the processor uses the pressure measurements to inversely obtain parameters of a fluid dynamics equation for mapping the lumen. |
