Results of FDA „Critical Path Initiative” to validate CFD
ASD Advanced Simulation & Design GmbH was one of 28 participants from 6 countries who contributed to an initiative of the U.S. Food and Drug Administration (FDA) aiming at the standardisation of Computational Fluid Dynamics (CFD) techniques used to evaluate performance and blood damage safety in medical devices:
The project goals are to
- establish a guidance document for computational studies in device review
- provide input into standards development for the use of computational fluid dynamics methods in medical device design and validation
- serve as benchmarks for future research and development in this area
In a first step, a simple nozzle design was chosen to perform blood flow analysis for a sudden expansion and a conical diffuser: CFD results for velocity and pressure distributions are compared to quantitative flow visualisation measurements. Simulation-based haemolysis predictions (obtained from 11 institutions) will be compared with in-vitro blood damage experiments. A further part of this initiative will consist of the computational analysis of a ventricular assist device.
First results were published at the 2009 Annual Meeting of the American Society of Artifical Internal Organs in Dallas, USA. A current survey about the improvement of flow modeling were summarized in a further poster.

New European research project „ARTreat“ started

Artheriosclerosis – this creeping disease which often remains undetected over years is in the main focus of many medical and biochemical research activities.
Characterised by a progressive degeneration of the arterial wall with the build-up of plaques to these walls, artheriosclerosis manifests itself with ischaemia, thrombosis, heard attack, stroke and sudden death.
ASD participates in a new European Research Projectungs with 18 partners from 13 countries and a financial volume of 10,5 Mio €. „ARTreat“ started in September 2008 and creates patient-specific models of the cardiovascular system and of artheriosclerotic plaque formation. The ambitious aim of the project is to provide cardiologists and vascular surgeons with tools which will be able to support them before, during and after a clinical intervention.
A three-level patient model will allow
· the reconstruction of the three-dimensional patient geometry,
· the modelling of the patient-specific blood flow, blood particle dynamics and
biological processes leading to plaque formation,
· the simulation of the interventionial procedures to treat plaqued arteries
Within „ARTreat“, ASD will apply its long-term experiences in the area of virtual stenting procedures as well as the company’s expertise in the simulation of complex physical-biological processes, investigate blood flow and coagulation behaviour in blood vessels.

ASD-online in a new design
Since the 1st of March 2009 the web site of the ASD GmbH - www.asd-online.com presents itself in a new design.
A clear structure, which meets the requirements of the wealth of services offered, facilitates the visitor in a quick orientation and easy access to additional information on particular simulation focuses.
Many new application examples from very different industry sectors give a comprehensive insight into the capabilities and results when using modern simulation tools.
Because we are permanently confronted with new, interesting tasks (surely interesting for a wide audience alike) we will probably never reach the state of completeness with our internet presentation. However, it is our claim to update the site on a regular basis and to enrich not only the News section with ambitious topics and interesting visualisations.
For that reason we hope that a regular visit at www.asd-online.com will be worthwhile for you.
We are looking forward to your feedback and suggestions.
