  14. 14. A bright idea that worksWhat have you got? Successful research results New scientific discovery Something that you have developed for another market but could find an application in the medical market. A new procedure A new tool As far as a proof of conceptWe have something that we believe in… www.team-consulting.com

  17. 17. Regulatory Framework US & EU Framework – FDA Vs. CE marking 510k vs. PMA, 90d vs. 1yr Must be defined at the beginning and on- going process Define your medical classification Build your Design History File Use of requirement tracking system and test procedure Risk mgt file (60601 3rd ed) Beware of SOUP Design for clinical trials www.team-consulting.com
