Abstract

The present invention is directed towards an apparatus (100) for pressure based lumen mapping. The apparatus includes a flexible, elongated member (30) having a portion insertable into the lumen, a device (40) for measuring pressure inside the lumen operatively connected to the insertable portion of member (30), a device (50) for moving the insertable portion (30) in a predetermined manner, wherein pressure is measured at various points during movement, and a processor (2) for processing pressure measurements, wherein the processor (20) uses pressure measurements to inversely obtain parameters of a fluid dynamics equation for mapping the lumen.
