METHOD FOR ASCERTAINING THE POSITION OF A MEDICAL INSTRUMENT IN A BODY
First Claim
1. A method for ascertaining the position of the head of a medical instrument in a vascular system, wherein the instrument can be inserted into the vascular system of a body and describes a path at least partially inside the vascular system, and the position of the instrument head is calculated from structural data, length data and the relative position between a reference point and the vascular system, wherein the instrument is guided past the reference point, the structural data represents the structure of the vascular system, and the length data represents the length of the path between the reference point and the instrument head.
