Abstract

The BiVACOR is a novel rotary Bi-Ventricular Assist Device (BiVAD) undergoing development to treat global end stage heart failure. The design includes left and right vanes positioned on a shared rotating hub to form a double-sided magnetically and hydro-dynamically suspended centrifugal impeller. The performance of the device was assessed in a pulsatile mock circulation loop replicating end stage bi-ventricular heart failure, and was shown to restore flow from pathological (2L/min) to normal levels (5L/min). A novel technique to balance the left/right outflow of the BiVAD was also investigated, for which a maximum relative left to right outflow differential of 1.8L/min was achieved at normal physiological afterloads. The in-vitro results encouraged device progression to in-vivo animal studies. Successful development of this BiVAD will provide a suitably miniature device for patients who require bi-ventricular assistance.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
