Project Overview
GPS Shoulder is an FDA-cleared intraoperative navigation system for total shoulder arthroplasty. The system provides surgeons with real-time positional data during shoulder replacement procedures, improving accuracy in component placement.
I developed prototypes and refined the navigation system through iterative testing with surgeon feedback, translating surgical workflow requirements into engineering specifications validated through bench testing and cadaver studies.
Technical Contributions
- Prototyping & Testing: Built and validated functional prototypes through benchtop testing and cadaver studies
- Clinical Collaboration: Observed shoulder surgeries to inform design decisions for ergonomics and tracker placement
- CAD & Tolerance Analysis: Precision 3D modeling with sub-millimeter tolerances for surgical accuracy
- Technical Documentation: Design specifications and validation protocols for FDA clearance
- Clinical Research: Co-authored peer-reviewed research on navigation accuracy and clinical outcomes
