U-Handle R&D Kit

The Complete Catheter Prototyping Ecosystem

Stop designing handles. Start validating your delivery systems.

What is the ProtoBrix System?

R&D engineers spend months designing and machining custom handles just to test a simple catheter prototype. 

ProtoBrix changes the paradigm. 

We provide a universal, off-the-shelf mechanical platform that replicates the ergonomics and functionality of a final clinical handle.

• The Concept: A modular housing with two independent actuators.

• The Workflow: Select your internal inserts, bond your catheter tubes (inner/outer) in 30 minutes, and start your bench tests immediately.

• The Compatibility: One system that scales from 6 Fr to 24 Fr.

Why the R&D Kit is your best option?

Prototyping is an iterative process. Your tube diameters, materials, or stroke requirements will likely change between Monday and Friday.

The R&D Kit is designed to ensure your lab never hits a technical dead end. It is the most cost-effective and flexible way to equip your cleanroom for any upcoming project.

Key Advantages of the Kit:

1. Iterative Freedom: With a full library of internal inserts (6 Fr to 24 Fr included), you can change your catheter size without re-ordering parts.

2. Parallel Testing: Two full U-Handle bodies allow you to compare two different designs side-by-side or run durability tests while assembling a second prototype.

3. Risk Mitigation: No more waiting for weeks if a tube diameter changes. You have the solution in the box.

4. Steerability Ready: Includes the components to configure your handles for either Dual-Translation (Sheath/Implant) or Steerable (Deflection/Translation) applications.

Need a more surgical approach? If you are working on a fixed-design project and only require one specific configuration, you can purchase the Single U-Handle here
