Abstract
An implantable blood pump includes a control unit storing patient specific settings. The control unit is configured to store patient specific settings. The patient specific settings can be used to determine a target operating speed for the blood pump and/or a target operating mode for the blood pump. The patient specific settings can include at least one of an operating mode for the pump, a set speed for the pump, a lower speed limit for the pump, a patient hematocrit value, a patient hematocrit date, a patient blood density, and a periodic log rate for event and periodic data.
Claims26
A blood pump assembly, comprising:
- an implantable blood pump configured to supplement or replace a pumping function of a heart;
- an implantable control unit communicatively coupled with the blood pump and storing preprogrammed patient specific settings on which control of the implantable blood pump is based;
- and
- a non-implanted external control unit configured to be operatively coupled with the implantable blood pump and to control operation of the implantable blood pump based at least in part on at least one of the preprogrammed patient specific settings communicated to the external control unit by the implantable control unit.
A blood pump assembly, comprising:
- an implantable blood pump configured to supplement or replace a pumping function of a heart;
- an implantable control unit communicatively coupled with the blood pump and storing preprogrammed patient specific settings on which control of the implantable blood pump is based, the preprogrammed patient specific settings including one or more of:
- (a) a patient specific set speed of the blood pump, (b) a patient specific low speed limit for the blood pump, (c) at least one of a patient specific hematocrit and a patient specific hematocrit date, (d) a patient specific blood density, (e) a patient specific periodic log rate for event and periodic data, and (f) a patient specific spoken language;
- and
- a non-implanted external control unit configured to be operatively coupled with the implantable blood pump and to control operation of the implantable blood pump based at least in part on at least one of the preprogrammed patient specific settings communicated to the external control unit by the implantable control unit;
- wherein the implantable control unit is configured to transmit the preprogrammed patient specific settings to the external control unit in response to a data request transmitted by the external control unit to the implantable control unit.
