Chronic heart failure patient

How does CCM work?

Optimizer IVs

The Optimizer IVs is a minimally invasive implantable device designed to treat Chronic Heart Failure (CHF) in patients that are symptomatic despite appropriate medical treatment. The device is based on novel Cardiac Contractility Modulation (CCM) technology, and delivers non-excitatory electric pulses.

The Optimizer system is currently the only device-based treatment option for the approximately 70 percent of CHF patients with advanced symptoms that have normal QRS duration and, hence, are not suitable for Cardiac Resynchronization Therapy (CRT).

The Optimizer IVs Implantable Pulse Generator (IPG) unit senses the heart’s electrical activity and delivers CCM signals via two electrodes placed in the heart’s right ventricle during the absolute refractory period (just after the heart contracts). The IPG is about the size of a defibrillator.

The Optimizer IVs has been implanted in more than 1,500 patients over the past eight years.

Optimizer IVs Charger System. Patients can recharge the IPG unit on a weekly basis using a home-based charger system, without supervision. Charging the device assures it has enough energy to provide CCM for years, minimizing the need for Optimizer battery replacement. The charger includes a display that provides instructions and feedback to the patient about the charging process. Data from each charging session is stored on a small memory card, which can be removed and reviewed during normal follow-up visits in the clinic.

OMNI II Programmer System. The portable programmer allows medical personnel to customize the Optimizer signal parameters according to individual patient needs. Dynamic evaluations can be made using the patient’s ECG and marker channels in order to optimize the delivery of CCM signals.
