`v. Troy R. Norred, M.D.
`Case No. IPR2014-00395
`
`
`
`I, Stephen J. Lombardo, declare as follows:
`
`1. I am a citizen of the United States and a resident of Columbia,
`
`Missouri. My post office address is the Department of Mechanical & Aerospace
`
`Engineering, University of Missouri, Columbia, Missouri 65211
`
`2.
`
`I am currently employed as a Professor in the Mechanical and
`
`Aerospace Engineering Department at the University of Missouri.
`
`3.
`
`From 1997 until 2003, I was employed as an Assistant
`
`Professor in the Chemical Engineering Department at the University of Missouri.
`
`4.
`
`In spring 2000, while I was employed as an assistant professor
`
`in the Chemical Engineering Department at the University of Missouri, I was
`
`approached by Dr. Troy R. Norred about a project he was working on concerning
`
`a prosthetic aortic valve adapted for percutaneous placement.
`
`5.
`
`Dr. Norred explained to me his ideas about prosthetic aortic
`
`valve adapted for percutaneous placement and we discussed if I could supply an
`
`engineering perspective on this. These discussions lead to the question of whether
`
`or not a prosthetic aortic valve could be held in place by a stent that was within
`
`the size range tolerated by the adult human anatomy without rupturing the aorta
`
`using mainly the frictional forces between the stent and the aorta. I indicated I
`
`could work on such a model if he provided me with detailed anatomical
`
`information.

`
`
`
`6.
`
`Over a period of weeks, Dr. Norred and I spoke as I
`
`gathered from him information about the aorta and the conditions within the
`
`aorta that might affect the ability of a stent to anchor in place.
`
`7.
`
`In early-to-mid June, 2000, I worked on developing initial
`
`drafts of the model. The model addressed aspects of whether a prosthetic aortic
`
`valve could be held in place by a stent that was within the size range tolerated by
`
`the adult human anatomy. A copy of the model I provided to Dr. Norred is
`
`Exhibit 2286. My handwritten notes are Exhibit 2219.
`
`I hereby declare under the penalty of perjury under the laws of the United States
`
`of America that the foregoing is true and accurate to the best of my knowledge
`
`and understanding.
