Warren Hancock (October 12, 1927 – July 17, 1999) was an American inventor and biomedical engineer, best known for his pioneering work in the development of heart valve technology.[1] He founded Hancock Jaffe Laboratories, which played a crucial role in advancing prosthetic heart valves and other biomedical innovations.[2]
Early life and education
[edit]Warren Hancock was born in 1927.[3] He attended Pepperdine University, where he developed an interest in biomedical engineering.[4] His educational background provided a strong foundation for his future endeavors in medical device innovation.[5]
Career and inventions
[edit]Hancock's career is marked by significant contributions to the field of cardiovascular surgery. In 1967, he founded Hancock Jaffe laboratories in Anaheim, California, to develop and commercialize innovative heart valve technologies.[6] Hancock's inventions have had a profound impact on the medical field, particularly in heart valve replacement and repair.[7]
