Intended Use

The BRANEMARK Bone-Anchored Hearing Aid (BAHA™) System is intended to be used as a bone-anchored, bone-conduction hearing aid. The device is indicated for use in patients requiring hearing amplification and with the following conditions:

  • Otological 1)
  • . congenital malformations of the external ear or microtia
  • . chronically draining ear which does not allow use of an air conduction hearing aid (e.g. external otitis, draining mastoid cavity)
  • other acquired malformations of the middle or external ear which . preclude the wearing of a conventional hearing aid
  • patients presently wearing, but dissatisfied with, traditional bone . conduction hearing aids or patients who are satisfied with their bone conduction aids but could benefit from the features of the BAHA-type device.
  • patients with conductive hearing loss due to ossicular disease and ● not appropriate for surgical correction or unable to be aided by conventional air conduction hearing devices.
    1. Audiological
  • . Pure tone average bone conduction threshold of the indicated ear better than or equal to 45 dB HL for model, Classic 300 and 60 dB HL for model HC-220 (average 500, 1k, 2k and 3k Hz); and a speech discrimination score better than 60% or reasonably good speech discrimination as evaluated by a qualified audiologist, based on the patient's particular needs.
    1. Psychosocial
  • patients (either by themselves or with the aid of others) must be ● able to maintain the abutment/skin interface of the BAHA. Therefore, careful consideration must be given as to the patient's psychological, physical, emotional and developmental capabilities to maintain hygiene. Patients should be at least 3 years of age.
  • Anatomical and Biological 4)
  • Biologically, titanium implants can be installed in most patients. ● Sufficient bone volume and bone quality should be present for a successful fixture implantation. Alternative treatments should be considered for patients having a disease state that might jeopardize osseointegration.
Device Description

The BRANEMARK Bone-Anchored Hearing Aid (BAHA™) System includes a titanium fixture which is placed in the temporal bone just behind the ear, an abutment, various accessories necessary for the placement and use of the fixture/abutment pillar, and a sound processor which is attached to the abutment. The fixture/abutment pillar is used as an anchor for the sound processor.

  • Device Name and Manufacturer: Nobelpharma USA, Inc., BRANEMARK Bone-Anchored Hearing Aid (BAHA™) System.
  • Predicate Products: BRANEMARK SYSTEM® - Bone-Anchored Craniofacial Prosthetic Attachment System (K945154), Audiant Bone Conduction Hearing Aid (K861971, K872168 and K841432), and other bone conduction hearing aids.
  • Device Description: A titanium fixture placed in the temporal bone, an abutment, accessories, and a sound processor.
  • Intended Use: Bone-anchored, bone-conduction hearing aid for patients with specific otological, audiological, psychosocial, and anatomical/biological conditions.
  • Comparison to Predicate: Stated that technological characteristics are "substantially identical and no additional questions regarding safety and effectiveness exist."

Therefore, I cannot fulfill your request for the specific details outlined in your prompt based on the provided text. The document is a "Summary of Safety and Effectiveness" from a 1995 FDA submission (K955713), which typically provides a high-level overview rather than detailed study results or performance data.

§ 874.3302 Bone-conduction hearing aid.

(a)
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.(b)
Classification. Class II.
