Abstract
Method for delivering a stent coupled with a catheter, to a selected position within a lumen of the body of a patient, the method includes the procedures of: selecting a single image of the lumen, among a plurality of images of an image sequence of the lumen, receiving a position input associated with the selected image and respective of the selected position, the position input is defined in a coordinate system respective of a medical positioning system (MPS), detecting the current position of the stent in the coordinate system, according to position data acquired by an MPS sensor attached to the catheter in the vicinity of the stent, superimposing on at least one maneuvering associated image of the lumen, at least one stent representation respective of the current position, and at least one marking representation respective of the position input, according to a real-time organ timing signal of an inspected organ of the body, maneuvering the catheter through the lumen, toward the selected position, according to the current position relative to the position input, and producing an output when the current position substantially matches the selected position.
