According to a recent MedCity News piece, the common reasons medical device prototypes fail to reach the market all share a root cause: early-stage programs focus on the technology problem while neglecting the business problem. The analysis suggests that this imbalance, rather than a lack of engineering skill, is what creates the commercialization gap.
The article implies that a prototype can be technically sound and still fail if the team has not defined who will pay for it, how it will be reimbursed, or why a customer would adopt it. In other words, moving beyond technical viability requires treating the business model as a core part of the development process, not an afterthought.
Because only one source was provided, the piece represents a single viewpoint. Still, it offers a practical warning for medtech founders: the hardest transition may not be from idea to prototype, but from prototype to a product that someone actually buys.
