The Unify CRT-D and Fortify ICD feature advanced battery technology, circuitry that allow for a smaller device and 40J of delivered energy (45J stored).

Because of the devices’ narrower shape, physicians can implant them using a shorter incision, leading to less time spent closing the incision and a smaller scar for the patient.

St Jude Medical‘s DF4 lead connector system further streamlines the procedure by reducing the number of connections between the defibrillation lead and the device.

The Unify CRT-D and Fortify ICD also incorporate the new CorVue pulmonary congestion monitoring algorithm.

The new feature alerts physicians when a patient’s heart failure may be worsening, as evidenced by changes in electrical signals that can be correlated to increased congestion, or fluid retention, in the chest area.

Both devices are designed to assist in the reduction of unnecessary shocks, including painless anti-tachycardia pacing, which can be used for fast ventricular arrhythmias prior to or while the device is preparing to deliver shock therapy and other enhanced technology for reducing inappropriate therapy.

St Jude Medical’s ShockGuard technology is designed to reduce inappropriate and unnecessary shocks for patients.
