In order to better understand what hypotubes is, as a professional CNC machining manufacturer, we will discuss the complete guide to hypotubes with you in this article
What is Hypotube?
A hypotube is a thin-walled metal tube designed with extreme precision to support medical and industrial applications. These tubes are typically used in catheters, hypodermic tubing, and surgical instruments, providing flexibility, strength, and corrosion resistance. Unlike standard tubing, hypotubes are manufactured with micron-level accuracy, making them ideal for fluid management, minimally invasive surgery, and high-performance engineering.
The most commonly used materials in hypotube production include:
- Stainless Steel (304 & 316L) – Provides high strength, corrosion resistance, and cost-effectiveness. Ideal for general medical applications.
- Nitinol (Nickel-Titanium Alloy) – Offers shape memory and superelasticity, making it perfect for catheter systems that need to navigate anatomical pathways.
- Titanium & Magnesium Alloys – Emerging biocompatible materials that are lightweight and strong, with potential applications in bioabsorbable implants.
Hypotube's main features and benefits
- High Precision: Manufactured to extremely tight tolerances for medical device applications.
- Corrosion Resistance: Withstands harsh sterilization environments and biological exposure.
- Thin Walls & Lightweight Design: Enables better patient outcomes in minimally invasive procedures.
- Customizable Wall Thickness & Diameters: Adaptable for specific medical and industrial needs.
Key Applications of Hypotube
Medical Applications
1. Hypotube in Catheter Systems
Hypotubes are a key component in catheter-based interventions, where they serve as the structural backbone of balloon catheters, stent delivery systems, and micro-guidewires. Their ability to maintain pushability, trackability, and flexibility allows them to navigate through complex anatomical pathways, making procedures such as angioplasty, neurovascular interventions, and electrophysiology more effective.
2. Minimally Invasive Surgery
The demand for thin-walled tubes in minimally invasive surgery (MIS) is growing rapidly. Laser-cut hypotubes with burr-free edges enable surgeons to perform precise, controlled movements while reducing tissue trauma. These innovations are particularly beneficial in:
- Endoscopic procedures
- Laparoscopic surgeries
- Robotic-assisted surgeries
3. Hypodermic Tubing for Medical Needles
Stainless steel hypotubing is the foundation of hypodermic needles, which require ultra-precise wall thickness for smooth fluid transfer and injection control. The manufacturing processes behind these tubes ensure sharp, burr-free bevels, allowing for reduced patient discomfort and consistent dosing accuracy.
