InControl was founded in 1990 in Redmond, WA to develop an implantable device for treating atrial fibrillation. In November 1995, InControl announced the first human implant of its Metrix atrioverter. The implantable atrioverter system consisted of an implantable atrial defibrillator (model 3000 or 3020) connected to right atrial (perimeter right atrial model 7205) and coronary sinus (perimeter coronary sinus model 7109)
