Submammary device implantation is a new method of inserting pacemaker devices that leaves no visible lump or scar.
In traditional implantation the device resides just under the skin. With the submammary implantation approach, skilled University of Iowa Hospitals & Clinics cardiologists place the pacemaker or defibrillator under the breast, between the chest muscle and ribs. Tiny incisions discretely located in the armpit and under the breast result in no visible scarring and greater comfort.
