Method of controlling an implantable pump system
First Claim
1. A method of controlling an implanted pump comprising the acts of:
- coupling a controller module to the implanted pump, the controller module including a processor, a display device, a user input device, and a digital memory having a first memory segment including a circular buffer and a second memory segment;
collecting operating parameters of the implantable pump;
displaying the collected parameters on the display device as selected via the user input device;
storing the collected parameters in the first memory segment;
continuously updating the stored operating parameters of the implanted pump such that a predetermined time period of the most recent data are stored in the first memory segment;
transferring a predetermined time period of the stored parameters from the first segment to the second segment upon pump failure; and
displaying the stored parameters on the display device as selected via the user input device.

Abstract
A controller module for an implantable pump system which has a pump motor includes a processor, a motor controller electrically coupled to the processor and adapted to power the pump motor such that the pump motor operates at a desired speed. The motor controller outputs digital representations of the pump motor operating parameters to the processor. A first memory device is coupled to the processor for storing the digital signals representing the pump motor operating parameters. The controller module further includes a user interface. The controller module may be coupled to a data acquisition system, which provides power and exchanges data with the controller module. The controller module may alternately be coupled to a home support system which provides power for the controller module and storage for system components.
