OBJECTIVES To develop an electromagnetic navigation technology for transjugular intrahepatic portosystemic shunt (TIPS) creation and translate it from phantom to an in-vivo large animal setting. MATERIAL AND METHODS A custom-designed device for TIPS creation consisting of a stylet within a 5 French catheter as well as a software prototype were developed(More)
 Identification of viable myocardial tissue is important for patients with a low left ventricular ejection fraction, since revascularization is effective only if the affected region is viable. After cineangiographic identification of occluded coronary vessels, the myocardial viability is usually determined using cardiac MRI or SPECT. Alternatively,(More)
Visualization of electromagnetically tracked instruments in pre- or intra-interventional fluoroscopic images requires a registration process between the coordinate systems of both modalities. We present in this paper a new approach for performing this procedure by using only two external fiducial markers with integrated electromagnetic sensors which are(More)
Assess electromagnetically guided in situ fenestration of juxtarenal aortic stent grafts in an in vivo model. Using a newly developed electromagnetic guidance system together with a modified, electromagnetically guidable catheter with steerable tip, an electromagnetically trackable guidewire and a custom in situ fenestrateable stent graft, a series of seven(More)
This work presents concepts for complex endovascular procedures using electromagnetic navigation technology (EMT). Navigation software interfacing a standard commercially available navigation system was developed, featuring registration, electromagnetic field distortion correction, breathing motion detection and gating, and state-of-the-art 3D imaging post(More)
