An acoustic monitoring system that is able to verify the success or
failure of the positional adjustment of a valve without the need for
additional energy during non-invasive reprogramming is provided. The
acoustic monitoring system includes a programmer for generating a
sequence of commands to adjust the valve mechanism, and for receiving
acoustic signals for analysis, a transmitter to implement the command and
adjust the valve, and a sensor for detecting an acoustic signal generated
from the valve during execution of the commands. A method for using the
acoustic monitoring system is also provided.
