What is the Millipede Transcatheter Annuloplasty Ring?
The Millipede Transcatheter Annuloplasty Ring System is an investigational device for secondary or functional mitral regurgitation (MR). It is designed to work like the rings used in open-heart mitral valve surgery to repair and restore the natural valve.

The Millipede System is a device that is delivered to your heart through a catheter (a long thin hollow tube) inserted into a vein in your groin. The part of the device that is left inside your heart to repair your mitral valve is a crown-shaped ring, made of a metal material called nitinol (the implant). The ring is placed around the opening of your mitral valve and secured in the tissue by using metal anchors (similar to a small screw) that secure the device into your heart tissue. The device is then tightened to bring the opening of your valve back to normal size, which makes the valve work properly again.
What happens during the procedure?
Your doctor will make an incision in your leg and insert a sheath (a hollow tube) into your vein to your heart.
The Millipede device, which is attached to a catheter, is then advanced through the sheath to your mitral valve.
Your doctor will position the Millipede device and then implant it on your mitral valve. Your doctor will use specialized x-ray imaging equipment to guide the entire process.
Once the Millipede device is in place, your doctor will adjust the size and shape of the ring to reduce the size of your mitral valve and reduce the MR.
After the Millipede device is implanted, the catheter and sheath will be removed, the incision in your leg will be closed, and the procedure will be complete.
