Document Type and Number:
WIPO Patent Application WO/2013/145134
Kind Code:
A1
Abstract:
This ventricular assist device pump is a ventricular assist device pump provided with a rotating part having an impeller, and a housing for accommodating the rotating part, the ventricular assist device pump being characterized in that the difference between the maximum and minimum flow of fluid, when the ventricular assist device pump is connected to a fluid-discharge source for discharging a fluid while increasing/decreasing the flow at fixed periods, is 40% or more of the difference between the maximum and minimum flow of fluid when the ventricular assist device pump is not connected to the fluid-discharge source. This ventricular assist device pump makes it possible to suppress the degree to which the health of a user deteriorates during long-term use, in comparison to conventional ventricular assist device pumps.
