Developing an interventional medical device is rarely a linear process. Clinical conceptsevolve,physician feedback reshapes priorities, and engineering teams must continually balance performance, manufacturability, regulatory requirements, and commercialization goals. At the same time, early-stage companies face pressure todemonstrateprogress to investors while advancing intellectual property and reducing technical risk.
Accelerating development is not simply about working faster. It requires making better engineering decisions earlier, rapidly validating ideas through functional prototypes, andmaintainingenough flexibility to adapt asnew informationemerges.
VivaCathfaced these same challenges as it worked to transform an innovative clinical concept into a functional medical device. Rather than waiting for every requirement to become fully defined, the company partnered with the engineering team now part ofAVto accelerate development through close engineering collaboration, rapid prototyping, and continuous iteration while reducing downstream risk.
“From the very first conversations,the engineeringteam [now part of AV]made us feel welcome. They were open, transparent, and willing to really show us their capabilities and technologies, which made it easy to see the potential for astrong partnership.”Mike Mirizzi, a seasoned R&D executive at VivaCath.
How Do You Turn Evolving Clinical Ideas into Functional Medical Devices?
One of the greatest challenges in early-stagemedical devicedevelopment is translating physician insight into designs that canactually bebuilt and evaluated. Physicians naturally focus on clinical outcomes and procedural workflows, while engineers mustdeterminehow those ideas can be transformed into manufacturable devices.
ForVivaCath, physician input arrived continuously, often reshaping the direction of the design. Rather than forcing premature specifications, engineers built an iterative development process that allowed ideas to be explored, tested, and refined through successive prototype cycles.
As Mirizzi explains:
“Our physician has a lot of ideas, and they come fast. The team [now part of AV] has been really good at listening to all of them, then distilling that input into something that can actually be built and tested.”
The valuewasn’tsimply producing prototypes quickly. It was combining rapid iteration with the engineering judgment needed to convert evolving clinical concepts into practical solutions.
Early-Stage Development Challengesand How to Turn Them intoOpportunities
| Challenges | How theAVTeam Responded |
| Physician requirements evolved continuously | Rapid design iterations incorporated clinical feedback. |
| Concepts needed to become functional devices | Engineering translated ideas into manufacturable prototypes. |
| Development timelines remained compressed | Continuous prototyping accelerated learning. |
| Funding milestones required tangible progress | Functional prototypesdemonstratedmeasurable advancement. |
Why Does Engineering Judgment Matter as Much as Prototype Speed?
Speed alone rarelydeterminesthe success of a development program.
The real advantage comes from shortening the time between learning cycles while ensuring every iteration moves the design in the right direction.
Eachmedical deviceprototype answered one question while raising another. Clinicians evaluated devices under realisticconditions,engineers interpreted the feedback, and design improvements followed quickly. Instead of debating theoretical concepts, the team made decisions using tangible devices and real-world observations.
As Mirizzi noted:
“The engineers [now part of AV] were experienced enough to say, ‘We can’t do it exactly like that, but here’s a solution that will work.'”
That ability to balance clinical intent with engineering practicality became one of the defining characteristics of the collaboration.

How Can Rapid Prototyping Accelerate Funding and Product Development?
Rapid prototyping does far more thanvalidateengineering concepts.
For early-stage medical device companies, prototypes help communicate ideas to investors, strengthen intellectual property, gather meaningful physician feedback, anddemonstratemeasurable progress toward commercialization.
As Mirizzi ofVivaCathindicates, these benefits extended well beyond the engineering team.
“Being able to dream something up and then have it in your hands fairly quickly has been critical for us, especially when raising capital and filing intellectual property.”
Instead of describing future possibilities, the company coulddemonstratetangible progress through functional devices.The project required rapid design iteration and close collaboration between the customer’s team andthe prototypingengineers to quickly evaluate and refine concepts.
Why Rapid Prototyping Matters
| Business Outcome | Development Benefit |
| Faster funding milestones | Demonstrates tangible progress to investors |
| Stronger intellectual property | Ideas become functional devices sooner |
| Better clinician feedback | Evaluate real devices instead of concepts |
| Reduced development risk | Identifyissues earlier when changes are less costly |
Today,AVexpands upon this approach throughLightspeed Lab®,AV‘ dedicated rapid prototyping organization. Engineers rapidly build, evaluate, and refine prototypes,often completing multiple design iterations in a single day. Integrated with our product development team,Lightspeed Lab® helps accelerate development from concept through commercialization.
Why Do Early-Stage Companies Need More Than a Prototype Shop?
As the program matured, conversations expanded beyond building prototypes.
The engineering team continually evaluated manufacturability, materialselection, cost reduction opportunities, and design simplification while preserving clinical performance.
According to Mirizzi:
“The team [now part of AV] does a great job communicating options. If there’s a way to simplify a design, reduce materials, or keep prototyping costs down, they explain that clearly so we can make informed decisions.”
The value extended beyond execution. It came from helpingVivaCathmake informed engineering decisions throughout development.
When compatibility with other technologies became important, the team responded quickly, helpingmaintainmomentum as the company continued advancing its program.
What Can Early-Stage Medical Device Teams Learn fromVivaCath?
VivaCath’sexperience reinforces several principles that consistently help accelerate development while reducing downstream risk:
- Build and evaluate prototypes early.
- Keepphysiciansclosely engagedthroughout development.
- Pair rapid iteration with experienced engineering judgment.
- Design for manufacturability from the beginning.
- Choose development partners that can support the journey from concept through commercialization.
Many of these practices also help reduce technical, manufacturing, and commercialization risk during early-stage development. For a broader discussion of risk management strategies, seeReducing Risk inInterventional DeviceDevelopment: Lessons from Early-Stage Programs.
How Does an Integrated Product Development Partner Accelerate Commercialization?
VivaCath’sexperience illustrates an important shift occurring across the medical device industry. Increasingly, early-stage companies are seeking integratedproductdevelopmentpartnersand Contract Development and Manufacturing Organizations (CDMOs)that can contribute far beyond engineering drawings or prototype fabrication.
The engineering team that partnered withVivaCathis now part ofAV, combining product design and development, rapid prototyping, testing, manufacturingexpertise, and commercialization support within one integrated team.
