   Medical devices


Origins of medical device technology

Advances in general anesthesia and sterile techniques enabled serious developments in medical - surgical technology to finally get underway in the early 1900s.  At that time, physicians were equipped with only a few instruments and a limited selection of medicines. In those days, doctors with small black bags made home visits and, using only a few instruments and their medical skill, diagnosed, prescribed and healed. 


A trip to a doctor's office or hospital would not find much more in the area of diagnostic instruments.  The X-ray machine had just been invented.


More recently, developments in medical devices have become more complex and diverse as engineering and medicine have become increasingly interdisciplinary, and the human body has been understood as a complex system of electrical fields, bio-mechanics, chemistry and motion.


Improvements in the fermentation processes through which many pharmaceuticals are grown, and the large-scale manufacturing techniques that mix, shape, package and deliver drugs in all their forms, have made life-saving medicines universally available. Modern pharmaceuticals have also provided greater protection from infection, which has enabled physicians to repair and replace damaged or worn-out body parts with engineered materials (bio-materials) and implants.


Today, engineers and scientists continue to work closely with medical professionals to develop artificial organs, replacement joints, life-enhancing systems, diagnostic and imaging technologies and other remarkable machines, materials and devices that save lives and improve the quality and effectiveness of health care services.
