Tech

Responsible for the assessment of the fatigue, process, and expanded size design of the nitinol
frame for the Cephea TMVR valve. Successful acquisition; now an Abbott subsidiary.
•	Cyclic Fatigue - Developed fatigue methods, protocols and reports, test fixturing, and in-house frame fatigue testers for cyclic strain life assessment of processed nitinol
components after final conditioning for intended nominal use case. Worked with contractual testing lab and FEA consultant for material assessment and safety factor
development. Interpreted clinical data for relevant boundary conditions.
David C Wang	•	Expanded Size Design - Understanding of nitinol material properties for design
considerations of expanded valve sizes. Worked with material and manufacturing
vendor, FEA consultant to prototype and verify nitinol frame design. Familiarity with target strain values during heat treatment, sheathing, and cyclic loading.
San Jose, CA	•	Process Development - Worked with manufacturing vendor to create a capable
process across whole workflow of nitinol part manufacturing: laser cutting, surface
conditioning, heat expansion, dimensional (optical) and visual inspection. Maintained
design intent while maximizing capability through feedback loops (visits, weekly
408.691.4852	meetings) with vendor and drawing releases. Travelled internationally.
•	DV Testing - Responsible for retention, corrosion, and rivet studies for FIH submission.
