Designed to Move. Built to Scale.
Bringing Steering and Articulation Designs to Life
Pull rings and articulating joints play a crucial role in the performance of many minimally invasive medical devices, including catheters, endoscopic tools, and robotic-assisted surgical instruments. These components translate physician input into controlled, predictable motion in applications where precision, sensitivity, and repeatability matter.
At AVNA, we help MedTech OEMs bring steering and articulation concepts to life through early-stage collaboration, design-for-manufacturing expertise, and scalable production support. From initial concept review through validation and full-scale launch, our engineering teams work closely with customers to refine component designs, evaluate manufacturing methods, and build confidence in performance at volume.
From Early Concept to Production-Ready Motion
Successful steering and articulation systems begin with a strong design foundation. During R&D, small decisions around materials, geometry, wire routing, weld approach, and assembly methods can have a meaningful impact on how a device feels, functions, and performs in production.
AVNA supports customers early in the development process with dedicated engineering resources, quick-turn prototypes, and collaborative design review. By aligning product performance goals with manufacturability from the start, we help OEMs move from concept to validation with greater speed and confidence.
Engineering Pull Rings and Articulating Joints for Repeatable Performance
Pull rings and articulating joints each play a distinct role in motion control, and each benefits from thoughtful engineering during development.
For articulating joints, AVNA helps evaluate the design and manufacturing factors that influence deflection, torque response, flexibility, and durability. This may include material selection, cut geometry, processing methods, and other features that support consistent motion.
For pull ring systems, AVNA helps focus on the details that support smooth actuation and reliable load transfer, including wire attachment, laser welding, tensile properties, routing, and assembly repeatability.
By addressing these details early, AVNA helps customers develop motion systems that are not only functional in prototype, but ready for validation, launch, and scale.
