1. 1 HCMDSS Workshop PANEL 1: Design for Future Medical Devices November 16, 2004 Presentation by: Robert Kircher, Jr. Dose Safety Company P.O. Box 22865 Seattle, WA 98122 bob@kontact.com 206-856-1995

2. 2 About Dose Safety Company Formed in 2003. Early phase. Developing IDC (Insulin Dosing Controller) software for closed loop control of blood sugar for insulin- dependent diabetics. Artificial pancreas = IDC + insulin pump + sensor. Ongoing preliminary clinical trial. Started September 2003. Beginning to address regulatory process.

3. 3 Safe and effective for its intended use Insulin pump BGL sensor By insulin pump mfgr. By Dose Safety The Future Challenge Insulin Dosing Controller (IDC)

4. 4 Meeting the Challenge 1)Executable, PVS formal design specification and provable correct implementation of the IDC system which meets Safety and Efficacy Requirements (in work.) 2)Need: PVS libraries for infusion pumps, glucose sensors, infusion sets, etc. 3)Need: Formal Methods compliance with FDA regulation. 4)Need: High fidelity human subject simulation model.

5. 5 2)Need: PVS libraries for infusion pumps, glucose sensors, infusion sets, etc. Customizable, building blocks required for the development and certification of medical device combinations. 3)Need: Formal Methods approach in compliance with FDA regulation. Tailor FM processes and artifacts as needed to comply with applicable regulation. Support development of new FDA guidance as necessary to minimize cert. efforts. Example: 21 CFR Part 820 Quality System Regulation, Subpart C Design Controls ( Google 21 CFR Part 820 ) 4)Need: High fidelity human subject simulation model Customizable model: gender, age, health, etc. Run real-time life scenarios: eat meals, get exercise. Use as plant model for closed-loop system development and test. Focus on areas that have most immediate benefit to public health and have the highest chances of success.
