Cardiac Support
Gets Minimally-Invasive

Nemo® is an implantable, minimally invasive cardiac pump designed to provide chronic, partial support to heart failure patients who are not eligible for LVADs and for whom there is currently no adequate treatment.



Nemo® is an investigational device.

  • Minimally-Invasive
  • True Support
  • Low Shear

A Therapeutic Challenge

Current LVADs are rarely implanted in either senior patients with advanced heart failure or those with less advanced stages of the disease, mainly because these devices are associated with a high adverse event rate and the surgical procedure is invasive. These patients’ health, however can deteriorate rapidly, and their quality of life is impaired; they are symptomatic despite optimal medical treatment, are often forced to stay at home, and frequently hospitalized. For these patients, the development of new device therapies would effectively stem the disease progression.

A Physiological And Minimally Invasive Pump

Nemo incorporates the wave membrane technology in a miniaturised and unique format in the field of cardiac support. Particularly compact, this physiological pump has the flattened shape of an implantable defibrillator, and can be implanted via an innovative, minimally invasive endovascular procedure; it does not require any opening of the sternum or thorax, and relies on interventional and surgical techniques. Such a procedure is less traumatic for the patients and unique in the field of chronic cardiac support.

Partial Support : A New Solution For Heart Failure

There is currently no solution for chronic and partial cardiac support, depriving many heart failure patients from efficient treatments. Thanks to the wave membrane technology, the Nemo implantable cardiac pump combines the advantages of a physiological functioning pump that limits the risks of complications, and a unique, minimally invasive approach. Able to provide a flow rate of 3L/min in a compact format, this pump is the solution to provide partial support to senior patients with heart failure – too frail to undergo the traumatic surgery required for an LVAD implantation – or patients with a less advanced stage of the disease, who could be relieved of their symptoms with a cardiac support.
