Description (Brief)
Subcutaneous implantable cardioverter-defibrillators (S-ICDs) are preventative devices that monitor heart rhythm, and provide defibrillation to patients with abnormally fast heart rhythms, or those at risk of sudden cardiac arrest. It can deliver both low energy and high energy shocks in order to get the heart back to a healthy rhythm. It is an alternative option for people with heart problems as its implantation differs from that of other defibrillators which have wires that are positioned in the heart. One major advantage of the S-ICD is that it is more minimally invasive because it avoids vasculature and cardiac tissue.
This S-ICD is implanted outside of the thoracic cavity, hence the name subcutaneous (below the skin), and the leads are embedded along the breastbone. The greater distance between the leads and cardiac tissue demands a larger shock, and therefore the subcutaneous defibrillators are slightly larger than transvenous defibrillators. This is beneficial for patients who have compromised venous connections or require that vasculature remains open for other health conditions. According to the American Heart Association, S-ICD devices have fewer complications than transvenous devices and are just as successful.
The ovoid-shaped Emblem MRI S-ICD Pulse Generator is for the prevention of sudden cardiac arrest. The device is implanted on the left side next to the rib cage. It does not use wires implanted in the heart to function. The FDA approved the Emblem MRI S-ICD in August 2016 for patients undergoing MRI scans.
Based in Marlborough, Massachusetts, Boston Scientific was founded by John Abele and Pete Nicholas in 1979 as a holding company in order to acquire Medi-Tech, a pre-existing medical instrument company. It develops and manufactures devices for many medical specialties. Their first product was a peripheral Angioplasty balloon. Between 1980 and 1990 Boston Scientific acquired ten medical device companies. In 2006 Boston Scientific acquired Guidant a Minneapolis based company that produced cardiovascular medical products including pacemakers and defibrillators.
