BiVACOR bionic heart in development in Texas

(Medical Xpress)—A bionic heart is under development in Houston, Texas, which has been steadily generating interest over the past several years.

The invention's roots are attributed to Daniel Timms, who is the founder of BiVACOR. Timms, a biomedical engineer from Australia, instigated the project in 2001 while studying at the Queensland University of Technology.
