Windmill Cardiovascular Systems

Windmill Cardiovascular Systems is a private U.S. medical device company developing implantable ventricular assist devices for patients with heart failure. Its core technology is the TORVAD platform, a pulsatile blood pump designed to provide gentler blood handling and synchronized ejection compared with conventional continuous-flow LVADs. The company appears to be focused on both full-support systems for end-stage heart failure and smaller devices for partial adult support and pediatric use. Publicly available materials indicate the company remains active and has been raising capital to finalize design work and prepare for first-in-human studies. Windmill is best characterized as a cardiovascular device developer rather than a therapeutics biotech or pharma company.
