Cardiac Dimensions

Cardiac Dimensions is a privately held structural-heart medical device company headquartered in Kirkland, Washington, developing transcatheter therapies for patients with heart failure and functional mitral regurgitation. Its lead product is the CARILLON Mitral Contour System, a minimally invasive, catheter-delivered implant placed in the coronary sinus to reshape the mitral valve annulus and reduce functional mitral regurgitation without open-heart surgery. CARILLON carries a CE Mark in Europe and remains an investigational device in the United States, where the company is completing the EMPOWER pivotal trial. Cardiac Dimensions closed an oversubscribed $53M Series E in March 2025 led by Ally Bridge Group. The company manufactures an implantable Class III medical device and operates no public developer program, API, or software platform.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
