(Oslo, 14 November 2024) Medistim ASA (OSE: MEDI) is a niche market leader within ultrasound technology with headquarters in Oslo, Norway. Medistim develops and commercializes medical equipment for use within cardiac, vascular and transplant surgery.
Today, the company announces the launch of the PATENT study, an open, prospective, multicenter trial aimed at evaluating the immediate clinical benefits and long-term prognostic value of intraoperative completion control using transit time flow measurement (TTFM) and high-frequency ultrasound (HFUS) imaging. The study focuses on patients undergoing bypass surgery for Critical Limb Threatening Ischemia (CLTI) below the knee.

Medistim is a global market leader in intraoperative quality assessment and surgical guidance in Cardiac surgery, serving 37% of the worldwide coronary artery bypass graft (CABG) market, which comprises over 700,000 procedures annually. The company continues to expand its presence in this field. As part of its growth strategy, Medistim aims to establish an equally strong position in Vascular surgery, with peripheral bypass surgery identified as a particularly promising target segment.
In 2010, estimates suggested that >200 million people worldwide were living with peripheral artery disease (PAD)1. Accurate data on the number of patients who have CLTI is lacking but a large study from the U.S. found that 11% of PAD patients developed CLTI2. The rapidly increasing worldwide prevalence of type 2 diabetes is likely to have a significant impact on the future incidence and prevalence of PAD and CLTI, as well as their morbid end points.
When PAD develops into CLTI, the patient will need immediate revascularization to reduce the risk of limb amputation as well as cerebrovascular and cardiovascular complications. Peripheral bypass surgery is one of the treatment alternatives, in addition to endovascular interventions. According to recent market research3, over 500,000 peripheral bypass surgeries are performed annually. In some countries, vascular surgeons already utilize TTFM and ultrasound for intraoperative completion control. Insights from the University of Helsinki4 have played a key role in shaping the design of the PATENT clinical study.
The PATENT study seeks to evaluate the immediate intraoperative clinical benefits of using TTFM and HFUS during peripheral bypass surgery in patients with CLTI. Additionally, the study aims to assess the prognostic value of TTFM and HFUS in predicting one-year clinical outcomes, helping to distinguish patients at high risk of graft failure from those at low risk.
The PATENT study will enroll approximately 450 patients across 15 sites in the USA, Europe, and Asia, with enrollment set to begin by the end of 2024. Recruitment is expected to take around two years, with each patient being followed for 12 months. Medistim anticipates study-related costs of approximately MNOK 25, spread over a period of 3-4 years. The return on investment is tied to the anticipated ability to demonstrate improved clinical outcomes through the use of TTFM and HFUS. This will drive adoption and enhance competitiveness compared to existing technologies like Doppler ultrasound and angiography. Medistim’s value proposition lies in offering a more comprehensive, reliable, and user-friendly alternative to these traditional methods.
The study will be led by Professor Michael Conte of the University of California, San Francisco, USA, who is the lead author of the Global Guidelines on the Management of CLTI. “I was intrigued by the solid experience and compelling data collected at the University of Helsinki, which demonstrated a clear correlation between graft flow values and graft failure,” said Professor Conte. “I am excited to take part in this project to provide further clinical evidence. I believe the PATENT clinical trial has the potential to becoming a landmark study with impact on clinical practice, to the benefit of CLTI patients worldwide.”
“We have been preparing for this study for quite some time and are eagerly anticipating the enrollment of the first patient,” said Kari E. Krogstad, President and CEO of Medistim. “This study has the potential to be a game-changer for Medistim, much like how the REQUEST study was transformative for the adoption of HFUS in CABG surgery. A trial of this caliber will not only generate significant attention but also spark interest among surgeons to evaluate and adopt our MiraQ devices, which are already approved for vascular applications. I am especially proud to announce a team of world-renowned investigators in vascular surgery leading this effort, including:
• Prof. Maarit Venermo, University of Helsinki, Finland; the Secretary General of the European Society of
Vascular Surgery (ESVS),
• Prof. Joseph L. Mills, Baylor College of Medicine, Houston, USA; the past President of the US Society of
Vascular Surgery (SVS),
• Prof. Nobuyoshi Azuma, Asahikawa Medical University, Japan; the President of the Japanese Society of
Vascular Surgery (JSVS), in addition to
• Prof. Michael Conte as previously introduced. ”
