Leslie Geddes | Biomedical inventor, 88

Purdue University bioengineering professor Leslie Geddes, 88, credited with more than 30 patents for biomedical devices, has died.

Purdue said Mr. Geddes died Sunday in West Lafayette, Ind. He retired as a distinguished professor in 1991 but continued the teaching and research work that resulted in his receiving the National Medal of Technology during a 2007 White House ceremony from President George W. Bush.

Mr. Geddes had said the invention he was proudest of was a material derived from hogs' small intestines that promotes new tissue growth. It has been turned into products used in more than 200,000 patients for soft-tissue repair and orthopedics.
