Product Group

Metal Shafts & Hypotubes

TE is a leading provider of high-precision metal shafts and hypotubes that are utilized in the development of minimally invasive medical devices solutions, including structural heart intervention, electrophysiology mapping and ablation catheters, and surgical robotics.

Connect to a strong legacy of innovation. With a strong foundation of expertise stemming from our acquisitions of MicroGroup and Creganna Medical, we are well-equipped to assist you from prototyping to large-scale production. We offer an extensive inventory of hypotubes that can be tailored to meet your specific requirements, enabling you to enhance performance, reduce lead times, and optimize costs in the development of your next-generation medical devices. 

Achieving optimal clinical performance for your hypotube begins with an in-depth understanding of the performance requirements for your product application. Attaining the best performance in one characteristic can often directly affect other characteristics. We have the engineering and manufacturing experience and expertise to support you in making these critical design decisions.

Hypotube Design Considerations for Optimal Performance

  • Transition – Custom engineered transitions to optimize product performance using process technologies and features such as laser spiral cutting, a skive feature or corewire weld. 
  • Trackability – A wide variety of coating technologies to maximize trackability, including discrete polymer overjacketing. 
  • Push and Torque – Optimization of these key performance characteristics ensures consistent and reliable location of the treatment site. 
  • Kink Performance – We offer both design advice and PoleVault™ hypotube product to optimize kink performance. 
  • Compression Resistance – Requirements should be defined in specific terms prior to prototype development e.g., a 1,000 mm shaft must exhibit less than 1% compression where a 4lb force is applied. 
  • Flexibility – Flexibility requirements can be specified in terms of the bend radius that must be achieved e.g., the shaft must be capable of bending around a 30 mm diameter. 

Partnering with us enables you to access a wide range of materials, engineering and manufacturing expertise, backed by a global footprint. Delivering the optimal hypotube for clinical performance and usability requires an advanced range of technical solutions.


  • Distal shaft technologies - The transition or finish of the distal end of the metal shaft is of vital importance to the overall metal shaft design, as it plays a pivotal role in overall clinical performance. Technology features of distal transition zones range from simple burr-free cuts to more complex spiral, skive, slot, crimp, taper, or flare designs. Additional features can be added to the distal transition zone such as corewires, coils, or custom micro-machined components to add additional flexibility or smooth the transition to the distal assembly.
  • Intermediate shaft design - Working with you, we can develop the optimal intermediate shaft design for your delivery device. We assist with critical design decisions relating to material choices, properties, and design alternatives. Advanced laser processing techniques can dramatically transform a metal shaft to increase flexibility and torque response. Appropriate femoral, radial, or brachial markers can also be applied. We also provide a range of coating solutions along the intermediate shaft from simple FEP coatings to polymer overjackets that combine the strength of a metal shaft with the flexibility of an outer polymer jacket. Your choice of coating solutions will impact catheter shaft lubricity and overall device trackability.
  • Proximal Shaft Design - Design choices for the proximal shaft will affect the overall usability of the delivery device or catheter. The most common and simple solutions include luers or hubs which facilitate basic access to the catheter lumen for the injection of fluids or drugs or the introduction of guidewires and sheaths. These components can be combined with an appropriate strain relief mechanism and over-molded to create a finished metal catheter shaft sub-assembly. More advanced proximal designs include complex handles and deployment mechanisms that integrate mechanical, electronic, or diagnostic mechanisms – all of which we can design and develop for you.
