EDL is an American Manufacturing Company

The genesis of EDL was support of NASA's Life Sciences Space Shuttle program.

The EDL crew successfully designed, turnkey manufactured, tested and flew 5 medical equipment systems aboard NASA Life Sciences Space Shuttle Missions supporting human physiology research.

These equipment systems and supporting apparatus were:

  • Single and Dual Channel Physiological Signal Conditioners (PSCs) worn by astronauts to accurately monitor key vital signs when outside the Space Shuttle (during Extra Vehicular Activities).
  • Precision Pressure Controller and Neck Chamber System (Baroreflex System) used to generate accurate and rapidly changing positive and negative pressures about the neck to measure Carotid BaroReflex response (controls blood pressure) while in a weightless environment.
  • Automatic Blood Pressure/Heart Rate Measurement System (ABPS).
  • System Venous Occlusion Plethsmograph (SVOP) worn by astronauts to measure body fluid shifts while in a weightless environment.
  • System Measurement Central Venous Pressure (SMCVP) – first invasive (In Vivo) human physiology response study performed by NASA Life Sciences, using sensor-instrumented catheter inserted into vein and worn by (the lucky!) astronaut to measure pressures around the heart region during lift-off, ascent and several hours into orbit. Also required custom design and fabrication of Bio Instrument Port (BIP) to provide safe penetration of astronaut's pressurized flight suit during lift-off and ascent.

"I wanted to say thanks for over 10 years of fantastic service. It's rare to find an assembly company that can do prototyping and handle medium to large scale production. When I first started my company I was doing work on a small scale and now it's rare not to have a product in the cue for assembly. The level of service has not changed. I'm always impressed with the quality of the assembly. Rarely ever an issue, but if there is you are always on top of figuring a solution to the problem. Read more ...
