A monitoring device for pressurised-air-driven diaphragm-based artificial heart assist devices [PDF]
Clinical Physics and Physiological Measurement, 1992 A non-invasive device has been developed to monitor the diaphragm position and the blood flow in artificial heart assist devices equipped with a pressurised-air-driven diaphragm. Light scattering from the diaphragm is used as a mechanism for measuring. Information about the position of several points of the diaphragm can be obtained.

Platelet Activation Markers in Patients With Heart Assist Device [PDF]
Artificial Organs, 2005 Abstract: Clinical use of heart assist devices is often associated with thromboembolic complications. We hypothesized that platelets may be activated in patients receiving assist devices and examined expression of the platelet activation markers CD62, CD63, and thrombospondin using flow cytometry in eight patients with Novacor left ventricular assist ...

Evaluation of the CorInnova Heart Assist Device in an Acute Heart Failure Model [PDF]
Journal of Cardiovascular Translational Research, 2019 While the number of patients supported with temporary cardiac assist is growing, the existing devices are limited by a multitude of complications, mostly related to contact with the blood. The CorInnova epicardial compressive heart assist device was tested in six sheep using an acute heart failure model.
