From Oslo to the World: Our Global Congress Presence Made Possible by ATA Carnets
A customer story by Medistim
Cardiac and vascular diseases continue to be the most common cause of death in the Western world. Over the past four decades, Medistim’s mission has been to serve patients, surgeons, and health care providers with innovative, cost-effective medical devices that measure blood flow and visualize atherosclerosis, thereby improving the quality and outcomes of cardiac and vascular surgery.
Medistim ASA is a Norwegian medical technology company headquartered in Oslo, a market leader in intra-operative transit time flow measurement (TTFM) and ultrasound imaging, and a provider of the MiraQ™ system to the global market.
Today, Medistim’s proprietary products are regarded as the standard of care in most European countries and Japan, while market adoption is growing in the USA, Asia, and the Middle East.
Sharing this technology with the global surgical community is a key priority for us, which is why participation in international congresses and exhibitions is essential to our work.

For many years, the ATA Carnet has been critical to our ability to attend and exhibit at international congresses. Transporting sensitive, high-value medical equipment across borders for temporary use requires reliable, efficient customs procedures. In practice, the ATA Carnet is the only viable way for us to exhibit internationally, allowing Medistim’s equipment to move smoothly while avoiding complex customs processes, financial guarantees, and delays in each country we visit.
The Oslo Chamber of Commerce has been a trusted and indispensable partner throughout this process. Their professionalism, efficiency, and deep expertise in ATA Carnet issuance ensures that our documentation is accurate and ready on time, even when deadlines are tight. Their team is consistently responsive and supportive, helping us navigate international trade requirements with confidence.
Thanks to the long-standing support of the Oslo Chamber of Commerce, we are able to maintain a strong and consistent presence at leading international medical congresses. This partnership enables us to represent Norwegian medical technology on the global stage and to continue advancing surgical quality and patient safety worldwide.
