About Littmann

Now it is possible not onlypossible to listen to crystal clear heart sounds, but to record, playback, store and share digital auscultation sounds.

Dr. Littmann revolutionised the stethoscope world when he introduced his patented diaphragm, transforming the stethoscope into the instantly recognised format still used today. Dr. Littmann went on to form Cardiosonics and sold two models of scopes, one for nurses, one for doctors. In 1967 3M acquired the Littmann stethoscopes brand and worked with Dr. Littmann to develop the range for generations of doctors.
