Heart valve startup Foldax has raised $20m in a Series D financing round led by Memorial Care Innovation Fund (MCIF).

The round was also joined by the company’s existing investors, including BioStar Capital, Kairos Ventures and Caltech, while Angel Physicians Fund (APF) and Sayan Bioventures joined as new investors.

In conjunction with the investment, MCIF managing director Bryant Heise also joined Foldax board.

Foldax intends to use the fund to enrol patients to the recently completed EFS clinical trial for its surgical aortic Tria biopolymer heart valve and initiate and enrol patients into the clinical trial for the surgical mitral valve.

The investment will also be used to support the development of the transcatheter aortic valve replacement (TAVR) device for the first-in-man clinical study.

Robotically manufactured Tria valves are designed to eliminate calcification, withstand stresses and strains without failure, and restore the patient quality of life without lifelong use of anticoagulants.
