Vascular Dynamics, Inc. is a medical device company founded in 2008 by Rainbow Medical Ltd. The company has developed a passive, catheter-delivered implant for the treatment of high blood pressure, referred to as hypertension. Their endovascular platform technology, MobiusHD, uses the body's natural baroreflex mechanism to modulate the autonomic nervous system, reducing the increased risk of heart disease, stroke, and kidney disease. The technology targets both afferent and efferent neural pathways to realize a reduction in sympathetic tone and an increase in parasympathetic activity. Clinical evaluations for heart failure and high-risk hypertensive patients are currently underway.
