Patent ID: 7778685

Claim:
A method for positioning an intravascular device located inside a tubular organ, at a desired location inside the tubular organ, the method characterised by: (a) obtaining a three-dimensional reconstruction of the tubular organ; (b) marking in the reconstruction the desired location at which the device is to be located; (c) obtaining a first two-dimensional X-ray image of the intravascular device located inside the tubular organ from a known perspective utilizing a processor that is responsive to respective positions of two radio-opaque markers flanking the intravascular device, the two-dimensional X-ray image taken after releasing contrast material; (d) obtaining a second two-dimensional X-ray image of the intravascular device located inside the tubular organ from the known perspective utilizing a processor that is responsive to respective positions of two radio-opaque markers flanking the intravascular device, the two-dimensional X-ray image taken without releasing contrast material; and (e) using the three-dimensional reconstruction of the tubular organ in combination with the first and second two-dimensional X-ray images of the device to position the device at said desired location inside the tubular organ.
