First in Human Study of the Icoms Flowmaker

Recruiting now · Not applicable

Conditions studied: Advanced Heart Failure

In brief

The Icoms® FlowMaker® is a cardiac assist system in the true sense of the word. As assisting means to help or rescue, its function is providing assistance to the heart, which will continue to have its own hemodynamic pump function. The effect of the Icoms® FlowMaker® is to add an additional quantity of blood flow on top of the native blood flow, during each systole. The heart continues to have its own contribution, but a more satisfactory blood flow is restored by the complementary action of the Icoms® FlowMaker® This study is a first in human test to evaluate the safety and the performance of the Icoms Flowmaker. The study population consists of patients with severe heart failure who are at high risk for a conventional LVAD and at high risk for a percutaneous driveline. Ten patients will be recruited and implanted In France , Slovenia and Czech republic. The study objectives are: o evaluate the safety and performance of the Icoms® FlowMaker® implantable device in patients with severe heart failure resistant to optimal medical therapy. --Primary Objective: Assess safety and performance of the device at 30 days post-implantation. Secondary Objectives: Evaluate the patient's hemodynamic and clinical status, and the device's functionality per technical specifications.
