Adjunct Professor
Bioengineering Department


I have advocated and supported the development of pediatric devices for my chosen field, cardiovascular device development, by being the industry lead (and co-PI) for the PediaFlow VAD development consortium that was NIH funded in 2 Phases from 2004 through 2013 and resulted in a de novo implantable Pediatric VAD design from conception to successful pre-clinical animal trials and HUD designation, and preparation for an HDE submission. In this role, I developed the justification and obtained support from my Board of Directors to support the PediaFlow VAD project as its co-Principal Investigator and for my organizations, MedQuest Products Inc., and WorldHeart Corp. to be the industrial partners for the consortium. While there is no doubt that the adult markets for such devices is much larger and it is harder to obtain industrial commitment to support the development of pediatric devices, if the case can be made with this consortium to reduce the costs of such development, then it could lead to better and more pediatric devices being developed. This is of interest since I believe that pediatric devices will not only meet the needs for pediatrics, but the learning and knowledge developed can be then leveraged to make better devices for the adult population as well. In addition, in my role as Coulter Program Director, we have assembled a set of Selection Committee members and Advisors that encompass domain expertise in legal, regulatory, reimbursement, business etc., and have implemented the Coulter process, several elements of which may be applied by the kind of service organization contemplated by this P50 consortium
