    Abstract: An apparatus and a method for determining the position of a medical instrument, particularly for the purpose of medical navigation. In order to use a simple system to provide a relatively inexpensive technique for determining positional information, the position and/or orientation of the medical instrument is determined by ascertaining the same on the basis of position finding operations. Electromagnetic fields are first measured and the results of relative field strength measurements are taken as a basis for ascertaining the direction of a line from a transmitter to a receiver. After this direction information is known, it is used to determine the positional information of the medical instrument.

  • Patent number: 10485903
    Abstract: An embodiment includes a process for treating an abdominal aortic aneurysm (AAA) endoleak with a shape memory polymer (SMP) foam device. First, a bifurcated stent graft is placed within the aneurysm while a micro guidewire is positioned within the aneurysm for future catheter access. Second, after placing the iliac graft extension, a catheter is introduced over wire to deliver embolic foams. Third, embolic foams expand and conform to the aneurysm wall. Fourth, embolic foams create a stable thrombus to prevent endoleak formation by isolating peripheral vessels from the aneurysm volume.

  • Patent number: 10436567
    Abstract: A method for locating mobile objects by identifying, on the basis of the objects before a network of magnetometers, a supplementary equation. The method includes connecting, by means of a relationship of equality, a first variable from a current system of equations to a term, the term being a predefined relationship between one or more other variables from the current system of equations or a constant numerical value. The method also includes replacing, in the current system of equations, the first variable with the term to which it is equal to obtain a new system of equations in which the number of variables for which the value needs to be estimated is smaller than in the current system of equations. The method further includes using the new system of equations instead in order to estimate the position/orientation/amplitude of a magnetic moment of one of the magnetic objects.
