Acoustic monitoring system
First Claim
1. An acoustic monitoring device for verifying the pressure setting of a valve mechanism in an implantable device having a plurality of adjustable valve settings, comprising:
- an extracorporeal housing having a top surface, a bottom surface, and a central opening;
a transmitter contained within the housing having a plurality of electromagnetic coils configured to generate an energy field sufficient to effect movement of the valve mechanism of the implantable device;
an acoustic sensor disposed within the central opening in the housing and electronically coupled to the transmitter for detecting acoustic signals generated by the valve mechanism during an adjustment cycle; and
a microprocessor configured to compare the detected acoustic signals to expected acoustic signals to verify the pressure setting of the valve mechanism.

Abstract
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.
