An atraumatic mock loop for realistic hemocompatibility assessment of blood pumps

Autor: Marcus Granegger, Stefan Jakubek, Daniel Zimpfer, Ulrich Kertzscher, Günther Laufer, Christoph Hametner, Michael Bernhard Fischer, Michael Röhrich, Andreas Escher, Moritz Bender

Conventional mock circulatory loops (MCLs) cannot replicate realistic hemodynamic conditions without inducing blood trauma. This constrains in-vitro hemocompatibility examinations of blood pumps to static operating conditions that do not reflect clin

Influence of a fully magnetically levitated left ventricular assist device on functional interrogation of implantable cardioverter defibrillators

Autor: Günther Laufer, Cesar Khazen, Michael Röhrich, Thomas Schlöglhofer, Dominik Wiedemann, Christoph Schukro, Daniel Zimpfer

Publikováno v: Clinical Cardiology

Background Electromagnetic interference between left ventricular assist devices (LVAD) and the telemetry wand of implantable cardioverter‐defibrillators (ICD) with impairment of ICD interrogation has previously been described in HVAD and HeartMate

Dynamic measurement of centering forces on transvalvular cannulas

Autor: Christian Grasl, Philipp Aigner, Francesco Moscato, Martin Stoiber, Heinrich Schima, Michael Röhrich

Publikováno v: Artificial Organs

In heart failure therapy, minimally invasive devices (transcatheter valves, catheter‐based cannulas or pumps) are increasingly used. The interaction with the valve is of special importance as valve damage, backflow, and thrombus formation are known

Noninvasive assessment of blood pressure in rotary blood pump recipients using a novel ultrasonic Doppler method

Autor: Thomas Schlöglhofer, Sarah Schneider, Daniel Zimpfer, Ulrich Kertzscher, Marcus Granegger, Bente Thamsen, Klaus Affeld, Michael Röhrich, Francesco Moscato, Heinrich Schima, Christoph Gross

Publikováno v: The International journal of artificial organs. 42(5)

In rotary blood pump recipients with low blood pressure pulsatility, current oscillometric methods to measure blood pressure are not applicable. The aim of this study was to use ultrasonic Doppler flow measurements to determine blood pressure in this

Electrospinning of small diameter vascular grafts with preferential fiber directions and comparison of their mechanical behavior with native rat aortas

Autor: Christian Grasl, Helga Bergmeister, Francesco Moscato, Martin Stoiber, Heinrich Schima, Michael Röhrich

Publikováno v: Materials Science and Engineering: C. 124:112085

Conventional electrospun small diameter vascular grafts have a random fiber orientation. In order to achieve mechanical characteristics similar to a native blood vessel, a controllable fiber orientation is of interest. In this study the electrospinni
