Abstract
An apparatus for starting operation of a motor of an implantable blood pump including a memory storing one or more default parameters for at least one of controlling and monitoring the startup operation. A processor operatively coupled to the motor is included, the processor is configured to: commence the startup operation based on the one or more default parameters; detect an error during the startup operation; adjust at least one of the one or more default parameters in response to the detected error; store the at least one adjusted parameter in the memory; and commence subsequent startup operations based at least in part on the at least one adjusted parameter.
Claims20
An apparatus for starting operation of a motor of an implantable blood pump, comprising:
- a memory storing one or more default parameters for at least one of controlling and monitoring the startup operation;
- and
- a processor operatively coupled to the motor, the processor being configured to:
- commence the startup operation based on the one or more default parameters;
- detect an error during the startup operation, the error including a failure to start the motor based on a plurality of pulses associated with a physiological state of a patient;
- update at least one of the one or more default parameters to an updated parameter different than the one or more default parameters in response to the detected error;
- store the at least one updated parameter in the memory;
- and
- commence subsequent startup operations based at least in part on the at least one updated parameter.
A method of adaptively adjusting operational parameters of a motor of an implanted medical device, comprising:
- commencing a startup operation based on one or more preset operational parameters;
- detecting an error during the startup operation, the error including a failure to start the motor based on a plurality of pulses associated with a physiological state of a patient;
- updating at least one of the one or more preset operational parameters with an updated parameter different than one or more preset operation parameter in response to the detected error;
- replacing at least one of the one or more preset operational parameters with the at least one updated parameter as a default parameter in the memory;
- and
- commencing subsequent startup operations based at least in part on the at least one updated parameter.
