From First Balloon to PQ: Why One Team Should Own the Whole Catheter Program

The Handoff Problem

In a lot of balloon catheter programs, the balloon comes from one supplier and the finished catheter gets assembled somewhere else. On paper it looks efficient. In practice, every handoff is a seam, and seams are where programs fail. The balloon house doesn't own the assembly. The assembly house didn't form the balloon. When something drifts at validation, no one owns the whole picture.

What Continuity Looks Like

At ReCurve, one engineering team owns the program from the first balloon formed through PQ and into commercial runs. The same people who form the balloon tip it, bond the shaft, and stand behind the finished device. Process parameters are documented as the program develops, not reconstructed afterward. There's no translation loss between a balloon spec and a catheter build, because it's one conversation the whole way through.

Validation as Confirmation, Not Discovery

Because the process boundaries were defined during development by the team that will run production, IQ, OQ, and PQ confirm what's already known instead of discovering it for the first time. We've taken more than 70 commercial programs through validation this way, across neurovascular, cardiovascular, gastrointestinal, urological, and peripheral applications. The programs that move fastest are the ones where the manufacturer was embedded from day one.

What to Demand

Before you split a program across a balloon supplier and an assembly house, ask what it costs you in ownership. Who answers when a tolerance drifts at validation? Who documented the process? Who stands behind the finished device? If the answer is more than one company, you've built a seam into your program before it started.

The ReCurve Approach

One team. One quality system. One clean room. Balloon forming on equipment we co-developed with BlockWise, full catheter development, and validation, all under one roof and one set of engineers. Whether you're a startup or an established manufacturer outsourcing a program, you get a device built by people who own every step of it.
