Introduction
EPMD was a medical technology startup later acquired by Philips. The product supported physicians during complex cardiac imaging and mapping procedures, where dense clinical information, real-time decision-making, and precise interaction design were critical.
I worked on the redesign alongside another UX designer, helping improve the information architecture, workflow clarity, and usability of the interface.
The challenge was not to simplify the product by removing complexity. The users were experts, and the clinical workflow required advanced controls and detailed information. The challenge was to make that complexity easier to navigate during high-pressure procedures.
Problem Statement
The existing system supported powerful clinical capabilities, but the user experience created unnecessary friction.
Physicians and clinical operators needed to move between imaging views, mapping data, procedural controls, and patient-related information while maintaining focus during a procedure. The interface contained many important tools, but hierarchy, navigation, and workflow structure made it harder to understand what required attention at each moment.
The product needed a clearer structure that could support expert users without slowing them down or hiding critical information.
Research
Because this was a specialized medical product, the research focused on understanding expert workflows rather than broad consumer behavior.
We reviewed the existing system, studied how physicians interacted with the product, and gathered feedback around procedural pain points. We looked for moments where the interface increased cognitive load, made navigation slower, or forced users to remember information that should have been visible in context.
We also analyzed adjacent medical and imaging systems to understand common patterns in clinical software: dense workspaces, persistent tool panels, real-time visual feedback, and clear separation between primary procedure views and secondary controls.
The research helped us understand that the interface needed to be redesigned as a working environment, not just a collection of screens.
Design Process
We started by mapping the procedural workspace: primary visualization, supporting tools, patient or procedure information, and secondary controls.
The key design challenge was how to organize complexity for expert users without oversimplifying the product.
We explored ways to improve hierarchy between primary clinical views and secondary controls, reduce unnecessary visual noise, create more predictable panel behavior, make key procedural information easier to locate, support expert users without over-explaining the interface, and create reusable UI patterns for complex clinical states.
Low-fidelity wireframes helped test structure before visual design. The goal was to explore layout logic: where the main clinical visualization should live, how supporting tools should be grouped, how panels should behave, and how users could move through the procedure without losing context.
Solution
The high-fidelity redesign translated the workflow structure into a more focused clinical interface.
The solution focused on clearer workspace composition, improved visual hierarchy, more consistent panels and controls, better separation between primary and secondary actions, a darker interface optimized for clinical visualization, and reusable components for procedural controls and supporting data.
The redesign aimed to help users stay oriented inside a dense system.
Impact
The redesign created a clearer foundation for a complex medical product used in high-stakes clinical procedures.
It helped the team communicate the product direction, align around core workflows, and move from fragmented interface patterns toward a more structured and scalable clinical workspace.
