Medical 21, Inc. Announces Approval to Begin Human Clinical Studies in Spain
FOR IMMEDIATE RELEASE
Medical 21, Inc. Announces Regulatory Approval to Initiate First-in-Human Clinical Study in Spain
Regulatory clearance enables launch of the MAVERICS Coronary Revascularization Study, advancing evaluation of the Company’s next-generation synthetic small-diameter bypass graft.
December 11, 2025
Minneapolis, Minn., December 11, 2025 /PRNewswire/ — Medical 21, Inc., a private medical technology company developing a novel regenerative small-diameter coronary bypass graft, today announced that it has received regulatory approval in Spain under the European Union Medical Device Regulation (EU MDR) to initiate the Company’s first-in-human, multicenter clinical trial of the MAVERICS graft, the MAVERICS Coronary Revascularization Study.
The MAVERICS graft is a next-generation regenerative vascular scaffold engineered to address the long-standing challenge of creating durable, small-diameter conduits for coronary artery bypass grafting (CABG). Its design integrates an absorbable polymeric scaffold with a nitinol wire frame, combining early mechanical support with a structure intended to guide the patient’s natural healing process. The scaffold architecture is designed to encourage cellular infiltration, neovascularization, and the gradual formation of native vascular tissue. By providing a consistent, readily available alternative to harvested vessels, the MAVERICS graft aims to streamline CABG procedures, reduce harvest-related morbidity, and broaden revascularization options for patients requiring coronary bypass surgery.
“We are pleased to have received all necessary regulatory clearances in Spain to begin our first-in-human study,” said Dr. Manny Villafaña, Ph.D. Sc., Chief Executive Officer of Medical 21. “This milestone marks an important step forward in validating the clinical potential of the MAVERICS graft and advancing our mission to transform coronary bypass surgery. For decades, surgeons have faced limitations in available conduit quality and quantity. The MAVERICS graft is designed to address these longstanding challenges, and we are eager to begin assessing its safety, performance, and biological integration in patients.”
The MAVERICS graft is an investigational device and has not been approved for commercial sale by the U.S. Food and Drug Administration (FDA) or any other regulatory authority.
