Abstract
According to an aspect, an implantable medical device includes an inflatable member, a fluid reservoir, and an electronic pump device. The electronic pump device includes a power converter configured to provide a voltage, a fluidic device including an actuator, a switch connected to the power converter and the actuator, and a controller configured to transition the switch between a closed state in which the power converter is connected to the actuator and an open state in which the power converter is disconnected from the actuator.
Claims20
An implantable medical device comprising:
- an inflatable member;
- a fluid reservoir;
- and
- an electronic pump device configured to transfer fluid between the inflatable member and the fluid reservoir, the electronic pump device including:
- a power converter configured to provide a voltage;
- a fluidic device including an actuator;
- a switch connected to the power converter and the actuator;
- and
- a controller configured to transition the switch between a closed state in which the power converter is connected to the actuator and an open state in which the power converter is disconnected from the actuator.
An electronic pump device for an implantable medical device, the electronic pump device comprising:
- a power converter configured to provide a voltage;
- a valve;
- a switch connected to the power converter and the valve;
- and
- a controller configured to transition the switch between a closed state in which the power converter is connected to the valve and an open state in which the power converter is disconnected from the valve.
A method for controlling a fluidic device of an implantable medical device, the method comprising:
- detecting a first signal to open a valve to transfer fluid between an inflatable member and a fluid reservoir;
- in response to the first signal, applying a voltage provided by a power converter to the valve;
- detecting a second signal to close the valve to maintain pressure in the inflatable member;
- and
- in response to the second signal, not applying the voltage provided by the power converter to the valve.
