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.

Claims

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 of:

selecting a single image of said lumen, among a plurality of images of an image sequence of said lumen;

receiving a position input associated with said selected image and respective of said selected position, said position input being defined 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;

maneuvering said catheter through said lumen, toward said selected position, according to said current position relative to said position input; and

producing an output when said current position substantially matches said selected position.

2. The method according to claim 1, wherein said procedure of superimposing is performed using only position input data which is associated with a real-time organ timing signal of said inspected organ which is substantially identical to the organ timing signal associated with said selected image.

3. The method according to claim 1, wherein said procedure of superimposing is performed by correcting said position input data according to a gap which is determined by the longitudinal location of said current position, said real-time organ timing signal and the organ timing signal which is associated with said selected image.

4. System for delivering a stent to a selected position within a lumen of the body of a patient, the stent being attached to a catheter, the system comprising:

a user interface for receiving a position input respective of said selected position;

a medical positioning system (MPS) for determining the current position of said stent within said lumen, in a coordinate system respective of said MPS, according to position data acquired by an MPS sensor attached to said catheter in the vicinity of said stent, and for registering said position input in said coordinate system; and

a processor coupled with said user interface and with said MPS, said processor superimposing at least one stent representation respective of said current position, while said catheter is being maneuvered within said lumen, 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 patient, on at least one maneuvering associated image of said lumen, said at least one maneuvering associated image being reconstructed from a plurality of two-dimensional images of said lumen, according to said position data and said real-time organ timing signal, said processor producing an output when said current position substantially matches said position input.
