In-Vitro Biocompatibility and Hemocompatibility Study of New PET Copolyesters Intended for Heart Assist Devices. [PDF]

Polymers (Basel), 2020
(1) Background: The evaluation of ventricular assist devices requires the usage of biocompatible and chemically stable materials. The commonly used polyurethanes are characterized by versatile properties making them well suited for heart prostheses applications, but simultaneously they show low stability in biological environments.

In Vivo Biocompatibility of an Innovative Elastomer for Heart Assist Devices. [PDF]

Polymers (Basel), 2022
Cardiac surgical approaches require the development of new materials regardless of the polyurethanes used for pulsatile blood pumps; therefore, an innovative biomaterial, a copolymer of poly(ethylene terephthalate) and dimer fatty acid (dilinoleic acid) modified with D-glucitol, hereafter referred to as PET/DLA, has been developed, showing non ...

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 ...

Risk Factors for Development of Stroke in Patients With Continuous-Flow Left Ventricular Assist Device Support as Destination Therapy [PDF]

Texas Heart Institute Journal
Background: Continuous-flow left ventricular assist devices (LVADs) are increasingly used as destination therapy. Although postimplantation stroke rates have been described in the context of bridge-to-transplant or mixed cohorts, stroke development is ...

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.
