Do helical stents induce swirling flow?


Peripheral arterial disease (PAD) leads to the development of atherosclerotic plaques in the arteries. These may eventually cause stenosis or occlusion of the vessel, leading to intermittent claudication or critical limb ischemia, which severely impact quality of life and survival. Treatment often involves stent placement, but unfortunately the long-term outcome for endovascular treatment is still suboptimal, particularly in the femoropopliteal segment.

Veryan Medical has developed a stent graft (BioMimics 3D stent) for the superficial femoral artery that focuses on mimicking the native vessel geometry, which has a helical or non-planar shape. The helical shape promotes swirling flow, which in turn ensures high, protective, values of wall shear stress, thereby increasing the treatment durability.

However, there is a gap in the knowledge regarding the actual presence of swirling flow in-vivo. Therefore, the aim of the current project is to ultimately perform in-vivo blood flow quantification in patients, using high framerate contrast-enhanced ultrasound vector flow imaging (VFI) techniques. Prior to the in-vivo measurements we will determine the accuracy of and optimize our VFI technique for capturing swirling flow using in-vitro models. Ultimately, this knowledge will be used to design stents for other peripheral vascular beds with the potential to enable endovascular techniques, thereby providing a new treatment options to improve the quality of life, limb salvage and survival for PAD patients.

Job description

You will positioned in the Multi-Modality Medical Imaging group of the University of Twente. Here you will be part of a dynamic and multidisciplinary team. The project is supervised by prof. dr. Michel Reijnen and dr. Erik Groot Jebbink.

Your role in the project:

Perform measurements to understand how swirling flow can best be visualized using 2D ultrasound techniques
Develop an in vitro setup to compare the hemodynamics of the Biomimics 3D stent to regular straight nitinol stents in a controlled environment.
Perform a pilot study, including patients treated with the BioMimics stent to visualize if swirling blood flow is indeed induced.  This study will be performed in collaboration with the Rijnstate Hospital Arnhem.

Your profile

  • You have a PhD in biomedical imaging, and a demonstrated record or strong promise of research productivity
  • You have experience with medical ultrasound techniques
  • You have affinity for both in vitro measurements and working with data acquired in clinical (pilot) studies
  • You are skilled in working in a laboratory (e.g. building/modifying set-ups, running analyses)
  • You have strong analytical and conceptual skills
  • You have an excellent command of English and good communication skills.

Our offer

We offer you a very challenging position in an inspiring multidisciplinary environment. The University of Twente offers a dynamic ecosystem with enthusiastic colleagues in which internationalization is an important part of the strategic agenda.

  • We offer a 18 months fulltime post doc position.
  • We provide a stimulating, modern research environment with world-class research facilities
  • You will be part of a dedicated team with which you will collaborate extensively with industry.
  • The post-doc salary is between € 3.353,- and € 4.402,- gross per month depending on experience and qualifications.
  • An annual holiday allowance of 8% of the gross annual salary, and an annual year-end bonus of 8.3%.
  • A solid pension scheme.
  • Minimum of 29 leave days in case of full-time employment.
  • We provide excellent mentorship and a stimulating research environment to accelerate your further professional and personal growth.
  • The University of Twente is situated on a green and lively campus with lots of facilities for sports and other activities.
