Intended Use

The Baha Attract consists of a percutaneously placed Implant Magnet and an external Sound Processor Magnet forming a magnetic connection across healed skin. A Baha Sound Processor is then attached to the Sound Processor Magnet. The Baha Attract is indicated for conductive, mixed and single sided deafness. Patients should have sufficient bone quality and quantity to support successful implant placement. The Cochlear Baha® Attract is intended for the following patients and indications for use: - Patients aged 5 and older - Patients who have a conductive or mixed hearing loss and can still benefit from sound amplification. The pure tone average bone-conduction hearing threshold (measured at 0.5, 1, 2, and 3kHz) should be better than or equal to 45 dB HL for use with the BP100 sound processor, and 55 dB HL for use with the BP110 sound processor. - Bilateral fitting is intended for patients who meet the above criterion in both ears, with bilaterally symmetric moderate to severe conductive or mixed hearing loss. Symmetrical bone-conductive thresholds are defined as less than a 10 dB average difference between ears (measured at 0.5, 1, 2, and 3 kHz), or less than a 15dB difference at individual frequencies. - Patients who suffer from unilateral sensorineural deafness in one ear with normal hearing in the other ear (i.e. Single-sided deafness: SSD™). Normal hearing is defined as a pure tone average air-conduction hearing threshold (measured at 0.5, 1, 2, and 3 kHz) of better than or equal to 20 dB HL. - Baha for SSD is 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.

Device Story

Baha Attract system provides bone-conduction hearing via transcutaneous magnetic coupling; consists of surgically implanted magnet and external sound processor magnet. System bypasses damaged outer/middle ear by transmitting vibrations through bone to cochlea. Used by patients with conductive/mixed hearing loss or single-sided deafness; operated by patient after surgical implantation. External sound processor captures acoustic signals, converts to mechanical vibrations, and transmits through skin via magnetic connection to internal implant. Benefits include improved hearing without percutaneous abutment, reducing skin-related complications. Clinical decision-making based on audiometric thresholds and patient candidacy for bone-conduction amplification.

Clinical Evidence

No clinical data provided in the summary document; substantial equivalence supported by bench testing and design validation.

Technological Characteristics

System comprises an internal implant magnet and external sound processor magnet. Operates via transcutaneous magnetic coupling for bone-conduction stimulation. Compatible with existing Baha BP100 and BP110 sound processors. Non-percutaneous design.

Indications for Use

Indicated for patients aged 5+ with conductive, mixed, or single-sided sensorineural deafness. Requires sufficient bone quality/quantity. Specific thresholds: conductive/mixed loss (PTA bone-conduction ≤45 dB HL for BP100, ≤55 dB HL for BP110); SSD (normal hearing in contralateral ear, PTA air-conduction ≤20 dB HL).

Regulatory Classification

Identification

A bone-conduction hearing aid is a wearable sound-amplifying device intended to compensate for impaired hearing and that conducts sound to the inner ear through the skull. The non-implantable components of a bone-conduction hearing aid, such as the external sound processor, are subject to the requirements in § 801.422 of this chapter.

Dear Mr. Bundy:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28. 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register,
