Partially-implantable middle ear implant system

37 GUDID devices

A battery-powered assembly of devices intended to compensate for impaired hearing by transmitting vibrations, from transduced sound waves, to the middle ear. It primarily consists of an external microphone and a vibrator implanted in the middle ear that is ...

Fully-implantable middle ear implant system

49 GUDID devices

An implanted assembly of sterile devices intended to compensate for impaired hearing by transmitting vibrations to the middle ear. It is powered by a battery that is recharged inductively, via an external device. It consists of a capsule, containing the bat...

Auditory cranial bone vibrator

27 GUDID devices

An electromechanical transducer intended to produce the sensation of hearing by vibrating the cranial bones. It can be used as an output device with an audiometer to measure bone-conduction hearing thresholds, and thus serve as an adjunct to air-conduction ...

Bone vibrator

7 GUDID devices

An electromechanical transducer intended to produce the sensation of hearing by vibrating the cranial bones. It can be used as an output device with an audiometer to measure bone-conduction hearing thresholds, and thus serve as an adjunct to air-conduction ...

Optical surgical navigation device tracking system

244 GUDID devices

A mobile assembly of mains electricity (AC-powered) devices intended to provide a physician with optical tools to track manual surgical instruments and locate target anatomical structures with respect to pre-acquired images (e.g., CT/MRI scan) or real-time ...

Optical surgical navigation device tracking system

121 GUDID devices

A mobile assembly of electrically-powered devices intended to provide a physician with optical tools to track manual surgical instruments and locate anatomical structures with respect to pre-acquired images (e.g., CT/MRI scan) or real-time data [e.g., endos...

Electromagnetic/optical surgical navigation device tracking system

62 GUDID devices

A mobile assembly of electrically-powered devices intended to provide a physician with both electromagnetic (EM) and optical tools to track manual surgical instruments and locate target anatomical structures with respect to pre-acquired images (e.g., CT/MRI...

Flexible video otorhinolaryngoscope, single-use

25 GUDID devices

An endoscope with a flexible inserted portion intended for the visual examination of some or all of the ear (external, middle and inner), nasal passages, paranasal sinuses, pharynx, and/or larynx. It is inserted into the body through the appropriate natural...

Electromagnetic/optical surgical navigation device tracking system

23 GUDID devices

A mobile assembly of mains electricity (AC-powered) devices intended to provide a physician with both electromagnetic (EM) and optical tools to track manual surgical instruments and locate target anatomical structures with respect to pre-acquired images (e....

Tympanic membrane contact hearing aid

9 GUDID devices

A collection of electronic devices intended to compensate for mild/severe sensorineural impairedhearing by transmitting transduced sound waves, either via light waves or an oscillatingelectromagnetic field, to a vibrator component in direct contact with the...

Tympanic membrane contact hearing aid ear tip transmitter

9 GUDID devices

An electronic component of a tympanic membrane (TM) contact hearing aid intended to be placed inthe external auditory canal to convert electrical signals from a sound processor into light signals orelectromagnetic energy for transmission to another componen...

Tympanic membrane contact hearing aid tympanic transducer

6 GUDID devices

An electronic component of a tympanic membrane (TM) contact hearing aid intended to be placed indirect contact with the TM and to convert signals into vibrations, which are then passed alongthe normal sound conduction pathway in the middle ear. The TM trans...

Flexible video otorhinolaryngoscope, reusable

5 GUDID devices

An endoscope with a flexible inserted portion intended for the visual examination of some or all of the ear (external, middle and inner), nasal passages, paranasal sinuses, pharynx, and/or larynx. It is inserted into the body through the appropriate natural...

Rigid video otorhinolaryngoscope

2 GUDID devices

An endoscope with a rigid inserted portion intended for the visual examination of some or all of the ear (external, middle and inner), nasal passages, paranasal sinuses, pharynx, and/or larynx. It is inserted into the body through the appropriate natural or...
