Design and function: a physical and electrical description of the 3M House cochlear implant system

Area of Science:

• Otolaryngology
• Biomedical Engineering
• Prosthetics

Background:

• The first patient-wearable, single-electrode cochlear implant was utilized in 1972.
• A redesigned cochlear implant system has been in clinical use since early 1982.

Purpose of the Study:

• To describe the 3M House cochlear implant system.
• To highlight improvements over the previous system.
• To detail features relevant for pediatric use.

Main Methods:

• Description of the implanted receiver.
• Description of the patient-worn signal processor, transmitter, and microphone.
• Mention of audiologist and patient fitting/testing instruments.

Main Results:

• The 3M House cochlear implant system comprises an implanted receiver and external components.
• The system includes tools for fitting and testing.
• Improvements over the older system are noted.

Conclusions:

• The 3M House cochlear implant system is a clinically available device.
• The system's design considers ease of use and effectiveness, particularly for children.
