Estimating Flap Thickness For Cochlear Implants
First Claim
1. A method of configuring a cochlear implant system, the method comprising:
- collecting individualistic data in a medical implant system comprising a medical implant implanted within a user and an external portion affixed external to the user, wherein the individualistic data comprises a plurality of measurements indicative of energy received at the medical implant in response to transmission from the external portion at a plurality of different powers;
comparing the collected individualistic data with reference data, wherein reference data is indicative of distances between a transmitter and a receiver in a reference medical implant system; and
configuring the cochlear implant system based at least in part on a result of the comparison.

Abstract
A flap thickness measurement system includes a reference cochlear stimulation system. The reference cochlear stimulation system includes a sound processor, a transmitter that transmits a telemetric signal, and a cochlear stimulator having a receiver that receives the telemetric signal and transmits a signal back to the transmitter. The system further includes one or more flap simulators having one or more known thicknesses that is positioned between the transmitter and receiver. Also included is a microprocessor that receives and processes data representative of tank voltage from the reference cochlear stimulation system.

8. A method of configuring a cochlear implant system comprising a cochlear implant implanted within a user and an external headpiece affixed external to the user, the method comprising:
-
transmitting a plurality of signals from a transmitter in the external headpiece affixed external to the user to a receiver in the cochlear implant implanted within the user, wherein each signal comprises a different power; measuring a voltage at the receiver in response to each signal; and determining a distance between the transmitter and the receiver by comparing the measured voltages to reference data. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A cochlear implant system, comprising:
-
an external headpiece, comprising a transmitter, and a microprocessor for storing reference data, wherein the reference data comprises data indicative of a receiver-to-transmitter distance as taken from a reference system, wherein the microprocessor further is configured to compare individualistic data received from the cochlear implant to the reference data to estimate a distance between the transmitter and the receiver; and a cochlear implant comprising the receiver, the cochlear implant configured to transmit the individualistic data to the external headpiece, wherein the individualistic data comprises a plurality of measurements indicative of energy received at the cochlear implant in response to transmission from the transmitter at a plurality of different powers. - View Dependent Claims (19, 20, 21, 22, 23)
