Will the MDR transition fall short of mitigating impact on IR and beyond?
In May 2021, the European Union (EU) Medical Devices Regulation (MDR) came into force to revise quality and safety standards for thousands of types of medical devices, and to reclassify in some cases. MDR was intended to come into effect in May 2020 after a three-year transition period, but this was delayed due to the COVID-19 pandemic. The transition period was recently extended again to allow device companies and manufacturers more time to plan their route to conformity with the new regulations, which many industry and healthcare stakeholders consider will make for slower implementation of new devices than under the MDR’s precursor, the Medical Device Directive (MDD). Interventional News sought out the views of interventional radiologists in Europe and the UK to capture the concerns within the sub-specialty relating to MDR, as well as those of industry.

Legislative measures taken with mitigation in mind, in Switzerland
With a more regulated device landscape on the horizon, the Swiss Parliament voted to allow US Food and Drug Administration (FDA)-approved devices onto the market in Switzerland, in November 2022. Swiss Medtech were among the backers of this decision and shared in a press release from the time of the vote that “more than 1,000 of the approximately 5,000 foreign manufacturers have already stopped supplying Switzerland with their products—they are not prepared to meet the additional requirements for the limited Swiss market, and patients in Switzerland are the ones to suffer”. This statement summarises the challenges that many companies, health professionals, and others involved in the provision of healthcare by means of medical devices face now, with the MDR transition period already in motion.

New study demonstrates IVC filters “safe and effective” in treating venous thromboembolism FEW ADVERSE EVENTS ARE connected to the use of inferior vena cava (IVC) filters when they are used to help prevent deep vein blood clots from developing into pulmonary embolisms (PE), according to the findings of the Predicting the safety and effectiveness of inferior vena cava filters (PRESERVE) trial, published jointly in the Journal of Vascular and Interventional Radiology (JVIR) and the Journal of Vascular Surgery Venous and Lymphatics (JVS-VL). The study and its findings have garnered attention, to the tune of presentations and discussions at some of the largest recent vascular and interventional radiology meetings. PRESERVE is a multicentre, prospective, open-label, nonrandomised trial that studied the safety and efficacy of IVC filters from six manufacturers. It was a joint effort of the Society of Interventional Radiology (SIR) and the Society for Vascular Surgery (SVS), carried out in cooperation with the US Food and Drug Administration. PRESERVE was sponsored by the Inferior Vena Cava Filter Study Group Foundation—a foundation created by SIR and SVS to receive and distribute funds supplied by manufacturers to the contract research organisation and sites. The study was conducted at 54 sites in the USA between 10 October 2015 and 31 March 2019. During that time, filters were implanted in 1,421 patients, of whom 1,019 patients had an existing deep vein thrombosis (DVT) or pulmonary embolism (PE). Trial results suggest that IVC filters were effective in helping to prevent PEs in patients experiencing a DVT. Approximately half of the patients in the study had their filters removed within three months of placement, and only one of 23 incidences of PE occurred within the 30-day post-filter removal observation period, according to study authors. “The question should not be only ‘should we place a filter?’ but ‘how should we offer comprehensive filterinclusive care of patients with venous blood clots, comprised of a detailed patient evaluation, a plan for retrieval after placement, and frequent followup with evaluation for filter removal or replacement,’” said Matthew S Continued on page 6
