#### Device Description

A bone anchored hearing system consists of a sound processor connected to an implant with a skin penetrating abutment. The implant is surgically anchored in the skull bone behind the ear. Vibrations generated by the sound processor are transmitted via the implant directly through the skull bone to the cochlea as bone conduction sound processor has a coupling so that it can be easily connected to and disconnected from the abutment by the user. Alternatively, it can be connected to head band accessories, to function as a conventional bone conductor. Using a computer based fitting system the sound processor can be adjusted to the patient's individual hearing requirements. The Ponto family is intended to be used with either the Ponto implant system or with specific compatible BAHA abutments/implants from Cochlear Bone Anchored Solutions (BAS).

#### Intended Use / Indications for Use

#### Intended use

The Ponto 4 sound processors are intended for improvement of hearing for patients with conductive and mixed hearing losses, bilateral fitting and single sided deafness.

#### Indications for use

Ponto 4 sound processors are intended for the following patients and indications:

· Patient with conductive or mixed hearing losses, who can still benefit from amplification of the sound. The pure tone average (PTA) bone conduction (BC) threshold (measured at 0.5, 1, 2 and 3 kHz) of the indicated ear should be better than or equal to 45 dB HL for use with the Ponto 4 sound processor.

· Bilateral fitting is applicable for most patients having a symmetrically conductive or mixed hearing loss. The difference between the left and right sides' BC thresholds should be less than 10 dB on average measured at 0.5, 1, 2 and 4 kHz, or less than 15 dB at individual frequencies.

• Patients who have a profound sensorineural hearing loss in one ear and normal hearing in the opposite ear (i.e. single sided deafness or "SSD"). The pure tone average (PTA) air conduction (AC) threshold of the hearing ear should then be better than or equal to 20 dB HL (measured at 0.5, 1, 2 and 3 kHz).

• Also indicated for any patient who is indicated for an air-conduction contralateral routing of signals (AC CROS) hearing aid, but who for some reason cannot or will not use an AC CROS.

The placement of a bone anchored implant is contraindicated for patient below the age of 5.

The Ponto 4 sound processors are intended to be used with either the Ponto implant system or with specific compatible BAHA abutments/implants from Cochlear Bone Anchored Solutions (BAS) (refer to the Ponto 4 labeling for specific compatible Cochlear models). In addition, selected Cochlear Baha sound processors can be used with the Ponto implant/abutment system (refer to the Ponto labeling for compatible Baha sound processor models).

{5}------------------------------------------------

#### Technological Characteristics

The Ponto 4 is a modification of the previously cleared sound processors (the Ponto 3, Power and Ponto 3 SuperPower in K161671), more specifically the Ponto 3 model, and represents the latest sound processor model in the Ponto bone anchored hearing system.

The Ponto 4 sound processor incorporates Velox S platform that is also used in the reference Oticon Opn S™ air conduction hearing aid legally marketed as class II, 510(k)-exempt devices. The Velox S platform introduces wireless 2.4 GHz Bluetooth connectivity and minor changes to the sound processing features. compared to the predicate Ponto 4 is smaller in size, which is enabled by moving the user controls to wireless accessories from Oticon A/S, and by smaller transducer and battery. Ponto 4 has a tamper resistant exchangeable battery drawer, side-neutral design, and a LED indicating status (e.g. low battery) of the sound processor.

The Ponto 4 housing and coupling are made of medical grade plastics that have been shown to be biocompatible and safe for human use.

This submission also includes minor modifications to the previously cleared accessory Genie Medical fitting software, and addition of compatibility with wireless accessories from Oticon A/S.

#### Discussion of testing

Testing of the Ponto 4 sound processors includes electroacoustic and EMC performance testing and firmware validation.

The Ponto 4 hardware is similar to Ponto 3 hardware, though smaller in size enabled by a smaller transducer and battery. The sound processing platform has been updated and a series of tests were conducted on the Ponto 4 sound processors to verify the design criteria and device performance with respect to electro acoustical performance. These tests include: Maximum output responses. Output for full-on gain at 50 dB SPL and 60 dB SPL, Equivalent input noise level, Total harmonic distortion, Frequency range, Battery voltage, Current Consumption, Battery lifetime, IRIL (input related interference level) and Processing delay, i.e. electro acoustical testing.

Ponto 4 sound processors have also been tested to (1) not emit excessive amounts of electromagnetic energy (EMC emissions); (2) operate as intended without performance degradation in the presence of an electromagnetic disturbance (EMC immunity) and ESD.

The above-mentioned tests verify that the Ponto 4 sound processors are as safe and efficient as the Ponto 3 sound processors. In all instances, the Ponto 4 sound processors functioned and the performance observed was as expected. Hence, we have come to the conclusion that further testing will not raise new issues of safety and efficacy.

#### Substantial Equivalence

The Ponto 4 sound processors have the same intended use as the Ponto 3 sound processor in K161671.

Ponto 4 sound processors have the similar principles of operations as the Ponto 3 sound processors. The sound processor is connected via an abutment to an implant placed in the temporal bone behind the ear, and the vibrations from the sound processor are transmitted directly to the inner ear through bone conduction. The implant and abutment are installed by a surgical procedure, and the sound processor can be connected and disconnected by the user by the snap coupling.

{6}------------------------------------------------

The sound processor is individually adjusted to the patient audiogram and needs by the Genie Medical fitting software by the audiologist. The volume and listening program can be changed by the user. On the predicate Ponto 3 sound processors this is done either on the sound processor itself or via the wireless accessories, whereas on the Ponto 4 the user can change the volume and program by using wireless accessories only. The same wireless remote functions are available for the predicate Oticon A/S 's Oticon S™ air conduction hearing aids, legally marketed as class II, 510(K)-exempt devices.

The sound processing platform and the wireless technology in the Ponto 4 sound processors are the same as those used in the legally marketed, class II 510(k)-exempt Oticon A/S air conduction hearing aids. The maximum force output and gain of the Ponto 4 sound processor are equivalent to those provided by the predicate Ponto 3 sound processors.
