Med-Dyne was originally founded as Johnson Medical Specialties, Inc. in Louisville, Kentucky in August of 1993 by E.W. Johnson, Jr.; at which time, the company's main focus was on the wholesaling of filters for oxygen concentrators. Within a few months of operation, Johnson Medical was able to acquire the assets of Terra-Con, Inc., a Vermont based company also specializing in air filtration devices. The Terra-Con operation was relocated to Louisville and operated under the name of Johnson Medical Specialties, Inc.

The following year, in 1994, Johnson Medical Specialties, Inc. purchased Medical Specialties Products, Inc., a Santa Ana, California company specializing in infant apnea monitoring accessories. The two companies merged to become Premier Medical Products, Inc., which operated from the Louisville location.

In 1995, Premier Medical Products, Inc. began manufacturing its own filters for oxygen concentrators. The company also acquired TransAmerica TENS, located in Connecticut who specialized in Transcutaneous Electrical Nerve Stimulation (TENS) units and accessories. The TransAmerica TENS operation was moved to Louisville and operated under the Premier Medical Products, Inc. name.

A year later, Premier Medical Products, Inc, changed the company name to Med-Dyne and still continues to operate under this logo. In 1997, Med-Dyne began manufacturing filters for Continuous Positive Airway Pressure machines, or CPAP filters. Med-Dyne continued to grow and in 1999 the production of infant apnea, ECG and sleep monitoring accessories began. During the next ten years, Med-Dyne has continued to develop and market Bio-Feedback accessories and devices. In 2005, Med-Dyne acquired Kentucky Kutters, Inc., a die press facility, as well as ElectraMold, a wire processing and injection molding company.

In 2006, Med-Dyne relocated to a state of the art facility near the University of Louisville campus. The current location houses our office facility, warehouse facility, and manufacturing site. Since 2006, Med-Dyne has submitted applications for and been approved by the Food and Drug Administration to manufacture pediatric electrodes and patient cables. These Class III medical devices each carry their own 510(k) appointed number, with the most recent being approved in June of 2008. The acquisition and merging of these companies has allowed Med-Dye to maintain a stable progression of medical device manufacturing and distribution over the years. Additionally, our outstanding customer service and commitment to above quality products has been upheld through our employees.

Thank you,
