FDA Clears Smaller ICD From St. Jude Medical
May 23, 2012 — St. Jude Medical Inc. announced U.S. Food and Drug Administration (FDA) approval of its Ellipse implantable cardioverter defibrillator (ICD). Designed with feedback from more than 200 physicians from around the world, the Ellipse 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 St. Jude Medical Ellipse ICD not only will streamline the implant procedure and improve patient comfort with its innovative design, but the device adds safety features with its new discrimination algorithms intended to minimize inappropriate shocks,” said Rahul N. Doshi, M.D., Fullerton Cardiovascular Medical Group Inc., Fullerton, Calif.
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.
“We feel collaboration with physicians in regards to the planning and design of our devices is imperative in order to develop truly breakthrough technologies,” said Eric S. Fain, M.D., president of the St. Jude Medical Cardiac Rhythm Management Division. “With the launch of the Ellipse ICD and the Assura family of implantable defibrillators, St. Jude Medical is able to provide physicians with a complete portfolio of devices that meet the individualized needs of patients, and our customers’ needs for reliable, efficient technologies.”
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.
