Abstract
A portable external device for a mechanical circulation support system includes first and second power sources, e.g. batteries and control electronics for redundant uninterrupted operation of an implantable blood pump. The control and power source module may be configured to accommodate a variety of wearable configurations for patient convenience and comfort.
Claims60
A portable external device for a mechanical circulation support (MCS) system comprising:
- a housing;
- a first power source removably connected to the housing;
- a second power source arranged within the housing;
- and
- control electronics arranged within the housing, powered by at least one of the first or the second power sources, and configured to control an implantable pump.
The device of claim 26, further comprising a second telemetry module configured to communicate information between the portable external device and one or more other devices according to a second wireless communication technique.
The device of claim 27, wherein the first wireless communication protocol is different than the second wireless communication technique.
The device of claim 29, further comprising a depression in which the capacitive sensor is arranged.
A mechanical circulation support system comprising:
- an implantable pump;
- and
- a portable external device comprising:
- a housing;
- a first power source removably connected to the housing;
- a second power source arranged within the housing;
- and
- control electronics arranged within the housing, powered by at least one of the first or the second power sources, and configured to control an implantable pump.
The system of claim 32, wherein the first power source comprises a first rechargeable battery configured to operate without recharge for a period of time in a range from approximately 4 hours to approximately 12 hours.
The system of claim 33, wherein the first rechargeable battery is configured to operate without recharge for a period of time approximately equal to 8 hours.
The system of claim 35, wherein the second rechargeable battery is configured to operate without recharge for a period of time approximately equal to 1 hour.
The system of claim 40, wherein the latch comprises two push buttons, each of which is biased into a locked position that inhibits removal of the first power source from the housing, and both of which are configured to be pushed into an unlocked position simultaneously to release the first power source for removal from the housing.
The system of claim 41, wherein the two push buttons are arranged on opposing sides of the housing such that the two buttons are configured to be pushed in approximately opposite directions to one another.
The system of claim 45, wherein the ratio of power consumed by the control electronics to power consumed by the implantable pump is approximately equal to 4/20.
The system of claim 48, wherein each of the energy dense power source and the power dense power source is configured to power the implantable pump.
The system of claim 57, further comprising a second telemetry module configured to communicate information between the portable external device and one or more other devices according to a second wireless communication technique.
The system of claim 57, wherein the first wireless communication protocol is different than the second wireless communication technique.
The system of claim 60, further comprising a depression in which the capacitive sensor is arranged.
