This specialized case study explores Kymanox’s approach to Human Factors (HF) regulatory strategy and User Interface (UI) evaluation through comprehensive validation study design. Our team of Subject Matter Experts (SMEs) collaborated closely with medical device stakeholders to implement measurable improvements across HF testing, intended user definition, Use-Related Risk Analysis (URRA), and FDA 510(k) submission preparation for connected central monitoring systems.
CHALLENGE
SOLUTION
RESULTS
- Medical device manufacturer required expert support developing HF regulatory strategy and effectively evaluating UI for connected devices.
- Device previously cleared in Asia market needed clearly defined intended users and user groups to produce results supporting FDA 510(k) submission.
- Efficient study design required for dual-device system comprising central monitor and transmitter used together by healthcare professionals.
- Navigation of software changes during validation necessary to ensure comprehensive UI evaluation.
- Updated and refined task-use error analysis and URRA, establishing foundation for design comprehensive HF validation study.
- Determined single Healthcare Professional (HCP) user group adequate for evaluating both central monitor and transmitter devices used together, building efficiency into study design.
- Strategically design validation protocol meeting FDA HF guidance and 510(k) submission requirements.
- Navigated additional software critical task changes during study conduct, ensuring full UI adequately evaluated and documented.
- Provided ongoing regulatory strategy consultation aligning study outcomes with FDA expectations.
- Successfully achieved FDA 510(k) clearance through robust HF validation demonstrating safe and effective use.
- Delivered efficient study design reducing timeline and resource requirements while maintaining regulatory rigor and data quality.
- Effectively managed dynamic software changes during validation without compromising study integrity or regulatory compliance.
- Established continued partnership with manufacturer for ongoing HF solutions and future regulatory support.
