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.

"For over a decade I have relied on EDL to support a variety of projects, they have never let me down and typically exceed my expectations. The quality of their work, economical pricing, and willingness to work as a team has significantly contributed to the success of numerous projects."

Bill, P. E., Senior Engineer
