Abstract:
1. Method for delivering a stent coupled with a catheter, to a selected position within a lumen of the body of a patient, the method comprising the procedures: selecting a single image of said lumen, among a plurality of images of an image sequence of said lumen; presenting said selected image to a user; receiving a position input from said user respective of said selected position, said position input being defined according to at least one mark, said at least one mark being graphically designated on said selected image, said mark exhibiting at least one dimension, said one dimension extending substantially along the longitudinal axis of said lumen; determining said position input in a coordinate system respective of a medical positioning system (MPS); detecting the current position of said stent in said coordinate system, according to position data acquired by an MPS sensor attached to said catheter in the vicinity of said stent; superimposing on at least one maneuvering associated image of said lumen, at least one stent representation respective of said current position, and at least one marking representation respective of said position input, according to a real-time organ timing signal of an inspected organ of said body, each of said stent representation and said marking representation exhibiting at least one dimension, said one dimension extending substantially along the longitudinal axis of said lumen; maneuvering said catheter through said lumen, toward said selected position, according to said current position relative to said position input, after determining said position input in said coordinate system; and producing an output when said current position, as represented by said stent representation, substantially dimensionally overlaps with said selected position as represented by said marking representation.
