A revolution in heart disease treatment

Cardiovascular disease affects 315 million people globally and is the world's leading cause of death. For the past quarter-century, it has been standard practice for heart surgeons to treat this by inserting small, mesh tubes called stents to widen or unblock patients' coronary arteries to restore blood flow. Unfortunately, many of those patients experienced additional issues—from blood clots to heart attacks—within years, sometimes months, of the procedure.
That's where DynamX, a new vascular technology from Elixir Medical, comes in. Like traditional stents, DynamX is minimally invasive and expands arteries to promote blood flow, but their unique design also enables them to restore arteries' natural defense mechanisms, helping patients avoid life-threatening events or costly and dangerous repeat procedures. The technology's promise to allow cardiac patients to heal more completely and live full, productive lives earned Elixir a spot as one of Fast Company 's 2025 Most Innovative Companies.
Novel technology, proven effectiveness
Traditional stents solve heart patients' immediate, critical need for restoring arterial blood flow. However, because they don't heal the arteries themselves, about half of patients re-experience an adverse medical event within 10 years, says Motasim Sirhan, Elixir founder and CEO.
DynamX is different. After six months, Elixir's implant transforms into an essential part of the artery itself as its mesh tube unlocks, freeing and reinforcing the artery's wall. The implant then gradually restores and adapts to the blood vessel's natural pulsing motion. 'You need to address the disease where it's originating, not the just symptoms of it,' Sirhan says. 'This is the first technology to do that.'
In the spring and fall of 2024, Elixir announced the results of a pair of large, international randomized clinical trials that demonstrate DynamX's favorable results. Patients with these implants had 65% fewer serious heart events and 78% fewer issues in the left anterior descending artery—which is critical for heart function as it supplies 50% of blood to the heart—than patients with traditional stent implants.
Last year, recognizing DynamX's promise, the U.S. Food and Drug Administration granted Elixir 'Breakthrough Device Designation' (BDD) on two applications of its DynamX technology: to treat heart artery blockage and serious artery blockages in the leg below the knee. BDD accelerates the review and approval process for novel technologies that may provide more effective treatment of life-threatening diseases and conditions.
Patient-focused solutions
As they developed DynamX, the company's researchers never lost sight of the seriousness and scale of the problem they were addressing. Many people begin to have cardiac issues in their 50s and 60s, requiring them to undergo multiple procedures. Patients often miss a substantial amount of work and sometimes can't participate fully in family activities. As Sirhan puts it, these hardships—on top of the millions or cardiac deaths annually—are 'not acceptable.'
Elixir's innovative solution is the product of a multidisciplinary team of experts in physics, biology, chemistry, engineering, and other fields. The researchers addressed the challenge from different perspectives but with a singular mission: serving patients. 'What was important for us,' Sirhan says, 'was being able to make a difference in patient treatment and to not be fazed by the difficulty of the mission.'
