Design, Manufacturing and Tests of an Implantable Centrifugal Blood Pump
An implantable centrifugal blood pump was developed for longterm ventricular assistance in cardiac patients. In vitro tests were performed, as wear evaluation, performance tests and hemolysis tests in human blood. Numerical computational simulations were performed during design process in order to predict its best geometry. Wear evaluations helped to select the best materials for double pivot b...
متن کاملComputational Analysis of Centrifugal Pump with 4,5,6,7 –bladed Enclosed Impeller
Centrifugal pumps are extensively used to transfer liquids to the required head with the help of centrifugal forces. The impeller forms the crucial part of the centrifugal pumps. Its shapes, dimensions, number of the blades affects the overall performance of the pumps.In this paper, effect of number of blades in the impellers are investigated using CFD tool. Considering the number of blades in ...
متن کاملThe CentriMag Centrifugal Blood Pump as a Benchmark for In Vitro Testing of Hemocompatibility in Implantable Ventricular Assist Devices
Implantable ventricular assist devices (VADs) have proven efficient in advanced heart failure patients as a bridge-to-transplant or destination therapy. However, VAD usage often leads to infection, bleeding, and thrombosis, side effects attributable to the damage to blood cells and plasma proteins. Measuring hemolysis alone does not provide sufficient information to understand total blood damag...
متن کاملThe Impact of Roller Pump vs. Centrifugal Pump on Homologous Blood Transfusion in Pediatric Cardiac Surgery.
Centrifugal pumps are considered to be less destructive to blood elements (1) when compared to roller pumps. However, their large prime volumes render them unsuitable as arterial pumps in heart lung machine (HLM) circuitry for children. In November of 2014, the circuit at Arnold Palmer Hospital, a Biomedicus BP-50 with kinetic assist venous drainage (KAVD) and 1/4″ tubing was converted to a rol...
متن کاملMagnetic drive system for a new centrifugal rotary blood pump.
The purpose of this investigation was to design a novel magnetic drive and bearing system for a new centrifugal rotary blood pump (CRBP). The drive system consists of two components: (i) permanent magnets within the impeller of the CRBP; and (ii) the driving electromagnets. Orientation of the magnets varies from axial through to 60 degrees included out-lean (conical configuration). Permanent ma...
