Clinical overview: Little bit of what gets done in these phases and how it gets allocated, timelines associated w/IRB approvals, CMS submissions, contracts,… Typical costs and cost drivers of each type study. Perspectives of startup (time &. burn rate) vs. strategic (multiple commercial product lines; NPD is not the focus of the entire organization).

  • Feasibility – Internally confirm that we know it works and address rules around FIH/EFS
  • Pivotal Study - Prove to everyone else that it works
  • Post Market Study

Clinical costs

  • Compare types of studies
  • Per patient, per site, per geography

Does the existence of bridging stent in a branch/fenestrated device affect the loads on proximal stent (as compared to a more standard infrarenal repair)?

Pre-market
Reimbursement: How does the device get paid for?
Pre-market considerations for reimbursement that factor into the business case. What if this device is different that it doesn’t match anything currently available and needs its own code?

Adam Borden

Post-Market
Clinical perspective – cost of complex repair.  How much does cost affect clinical decisions?  Do surgeons know what various items cost at their hospital? How is cost discussed with patients?

Sunita Srivastava, MD

4:20-4:30pm

Steps 2 and 5/6 (VC and strategics)

VC Funding
NOTES: What is an attractive VC investment?  How do they arrive at a valuation? What do they look for? Market, team, maturity of the technology, customer obstacles to adoption, clear regulatory path? What exit value is needed to be a viable investment for a particular device?
