Cochlear Bone Anchored Solutions

Cochlear Bone Anchored Solutions is a company based in Gothenburg, Sweden that manufactures and distributes bone conduction hearing solutions under the trademark Baha.

It is a semi-implantable, under the skin bone conduction hearing device coupled to the skull by a titanium fixture.

[2] Professor Per-Ingvar Brånemark discovered osseointegration in the 1950s, which allows titanium implants to fuse with human bone.

In the mid-1970s, Brånemark, together with his ENT colleague Dr Anders Tjellström, glued an Oticon bone vibrator to a snap coupling fitted to a dental implant and then connected it to an audiometer.

[3] Doctors Anders Tjellström at Sahlgrenska University Hospital in Gothenburg, Sweden, implanted and fitted the first patient with a Baha sound processor in 1977.
