Tiny ring could fix leaky heart valve without open surgery

NCT ID NCT04147884

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early study tested a new device called the Millipede ring, which is delivered through a catheter to tighten the mitral valve in people with functional mitral regurgitation (a leaky valve). Only 4 participants were enrolled to see if the procedure is safe and technically possible. The goal is to offer a less invasive alternative to open-heart surgery for heart failure patients.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Millipede Transcatheter Annuloplasty Ring System (a repair device implanted via catheter to tighten the mitral valve)

What this could lead to

If successful, this device could offer a less invasive way to fix leaky mitral valves, potentially reducing heart failure symptoms and avoiding open-heart surgery.

What could go wrong

This is a very early feasibility study with only 4 participants, so results may not apply broadly. The device could cause serious complications like stroke, bleeding, or valve damage.
