St. Jude Medical Ellipse Implantable Cardioverter Defibrillator

Industry’s Smallest High-Energy Device Inspired by Input from Hundreds of Physicians


May 23, 2012

Designed with feedback from more than 200 physicians from around the world, the Ellipse implantable cardioverter defibrillator (ICD) offers physicians unique design advancements, resulting in the industry’s smallest high-energy ICD.

The Ellipse ICD’s unique shape was conceptualized by physicians during focus groups where they crafted in clay their vision for the ideal device design. The physician-inspired shape is designed to increase patient comfort and physician ease-of-use. The angled header and rounded edges were designed to improve the way a lead wraps around the device once connected, which can result in a smaller incision and reduced pocket size for the device.

The Ellipse ICD features SecureSense RV lead noise discrimination, an algorithm that expands St. Jude Medical ShockGuard technology, differentiating lead noise (over-sensing of electrical signals) from true ventricular tachycardia (VT) or ventricular fibrillation (VF) episodes requiring therapy. The technology is expected to assist physicians by more proactively lowering the risk of lead-related complications through its ability to automatically withhold tachycardia therapy in the presence of lead noise.

The Ellipse ICD is the smallest volume, high-voltage device on the market. It allows for 36 J in delivered energy, providing a downsized option without compromising on energy, longevity, safety or reliability. Similar to the Fortify Assura ICD, the Ellipse ICD adheres to the ISO DF4 connector specification, which reduces the number of connections between the defibrillation lead and the device. St. Jude Medical was the first manufacturer to offer DF4 technology in early 2009.

The St. Jude Medical high-voltage portfolio is augmented by the Durata defibrillation lead, which has more than 10,000 leads actively monitored in prospective active registries and more than 27,000 patient years of data.

St. Jude Medical Inc. announced U.S. Food and Drug Administration (FDA) approval of the Ellipse ICD in May 2012.
