Cochlear Implants—Med-El

Med-El Tempo+ Cochlear Implant Audio Processor (demo)

The Med-El Tempo+ cochlear implant audio processor was made by Med-El GMBH of Innsbruck, Austria in 2004.

This cochlear implant audio processor worked with the Pulsar or earlier Combi 40+ cochlear implants.

Note: this is a demo model put out by Med-El so potential cochlear implant users could see and handle it.

The Tempo+ consisted of two parts—the behind-the-ear microphone/audio processor and the transmitting coil.

There were two versions of the battery pack. The angled one (shown here) and the straight one (not shown) where the battery compartment is in line with the audio processor.

Side view of the MedEl Tempo+ cochlear implant audio processor showing the ear hook extended. The ear hook could be extended up to about 5/16" (0.9 cm) to fit different-sized ears. The extension pins just pushed in and out to suit the wearer, or could be pulled right out to change the ear hook to a different size.

There were 8 different-sized ear hooks. The one shown here is the size "H", the medium angled ear hook.

Close-up view of the top "shoulder" of the MedEl Tempo+ cochlear implant audio processor module showing the "door" (upper left) to the auxiliary audio input jack. "Door" shown in closed position. The ridges (line on the left and another one on the other side) gave you something to grip as you pulled the "door" out to open it.

Close-up view of the top "shoulder" of the MedEl Tempo+ cochlear implant audio processor module showing the "door" to the auxiliary audio input jack.

To access the audio input jack, you first pulled the "door" straight out, then rotated it upwards to access the input jack. The "door" is here shown half opened.

Close-up view of the back of the Med-El Tempo+ cochlear implant transmitting coil showing the beige cover hiding the electronics.

Covers for the transmitting coil were beige (shown here), black (called anthracite), white and brown.

The transmitting coil measured 1¼" in diameter by ¼" thick (3.2 x 0.6 cm).

The cable joining the coil to the audio processor was 3¼" long (8.2 cm).

Close-up view of the inside of the Med-El Tempo+ cochlear implant transmitting coil with the beige cover removed showing the circuit board with the magnet in the center.

There were different sizes of magnets with different strengths. You used the one with enough strength to hold the transmitting coil on the outside of your head to the corresponding magnet in the implanted module.

Close-up view of the reverse side of the circuit board of the Med-El Tempo+ cochlear implant transmitting coil showing the 8 turns of the transmitting coil with the magnet in the center.

The magnet in the center of the coil was oriented such that it attracted the corresponding magnet in the the center of the Pulsar cochlear implant, thus holding the transmitting coil in place on the outside of the head.

View of the battery compartment of the MedEl Tempo+ cochlear implant audio processor module showing the three No. 675 batteries in place.

Cochlear implants used a more powerful version of the No. 675 batteries than hearing aids used to give them longer life such as the PowerOne No. p675 Zinc-Air Cochlear Implant battery.
