Appearance Models & Proof of Concept

Appearance modeling is the first stage of medical device prototyping. In this phase, the team will develop drawings, rendered images, or physical (usually non-functional) mockups of the device. These pieces can be used to gauge investor interest, inform preliminary patent research, or answer key questions about usability and product positioning.

Next up is proof of concept. In this stage, the device should begin to take shape in terms of function, but not necessarily final appearance. This prototype will allow for testing feasibility, investigating risks, evaluating material selection, and assessing initial performance of critical aspects. 

Alpha and Beta for Testing

An Alpha prototype, sometimes done as a proof of concept, is constructed of materials and components that may or may not be the same as the final product. The project team is learning critical aspects of the design or manufacturing process, and at this point is making prototypes with methods quicker than a beta prototype to allow for rapid iterations if needed.

A Beta prototype should resemble as close as possible the commercial product and should be “production-equivalent”. This is a more intensive process that can take months or longer to complete. It may not have been built at the production commercial volume but every process and step should be the same. Beta prototyping allows for verification and validation testing to ensure that the device performs its intended function. This testing will support a regulatory submission.
