Abstract
A controller for an implantable blood pump includes processing circuitry configured to initiate a suction response algorithm if a combination of a number of detected suction events multiplied by a suction event variable and a number of non-suction events multiplied by a non-suction event variable exceed a predetermined threshold.
Claims20
A controller for an implantable blood pump, comprising:
- processing circuitry configured to initiate a suction response algorithm if:
- a combination of a number of detected suction events multiplied by a suction event variable and a number of non-suction events multiplied by a non-suction event variable exceed a predetermined threshold.
A method of operating an implantable blood pump, comprising:
- initiating a suction response algorithm if a combination of a number of detected suction events multiplied by a suction event variable and a number of non-suction events multiplied by a non-suction event variable exceed a predetermined threshold.
A controller for an implantable blood pump, comprising:
- processing circuitry configured to initiate a suction response algorithm if:
- a combination of a number of detected suction events multiplied by a suction event variable less than one and a number of non-suction events multiplied by a non-suction event variable less than one and less than the suction event variable exceed a predetermined threshold, each detected suction event and non-suction event being determined over a one-second interval.
