Biomedical Inventions

Many of the biomedical inventions were created by biomedical engineers. One example was the insulin. Leslie Geddes, a professor emeritus at Purdue University, is an electrical engineer and inventor who has taught over two thousand biomedical engineers. He received the 2006 National Medal of Technology from President Bush for his contributions to the field. He also invented the miniature defibrillator. In addition, he contributed to the development of burn treatments and insulin. Some of his other co-discoverers include John Macleod of Case Western Reserve University and Robert M. Nerem of the Georgia Institute of Technology.

Bio-artificial liver

Bio-artificial liver tissues are synthetic organs that can replace missing liver tissue in the absence of a donor liver. The technology involves using an autogenic source of cells for transplantation and a biocompatible scaffold for implantation. The biocompatible scaffold is commonly made of collagen-based hydrogels. However, collagen-based scaffolds are susceptible to contraction, which can cause abscesses, which can be fatal. A novel collagen-based scaffold is being developed to minimize this contraction.

The process begins by drawing blood from the patient. The blood is then separated into plasma and blood cells, which are then introduced into a bioreactor. The slices are then arranged between two stainless-steel meshes, preferably parallel, in the bioreactor. The meshes are then pressed to ensure they are flat and have an open surface.


Hemodynamic instability can be the result of a variety of health problems. It can be sudden and unexpected, but symptoms like shortness of breath, weight changes, …
