Nitinol Tube Minimally Invasive Catheter Material

Description

• Precision Nitinol Tube: Shape Memory Solutions for Advanced Applications

  Generally speaking Nitinol tubes—engineered from an exact alloy composition of 55% nickel and 45% titanium—are revolutionizing performance standards in next-generation medical devices. Notably, by leveraging their shape memory and superelastic properties, these advanced tubes automatically return to their original form when heated. Therefore, they have become essential components in life-saving, minimally invasive procedures. Moreover, thanks to our proprietary process innovations, we now offer Nitinol tubing with outer diameters up to 16 mm—significantly unlocking new dimensions in device design and function.

  Why Choose Nitinol Tubes Over Conventional Tubing?

  Compared to stainless steel or polymer alternatives, Nitinol tubes offer several transformative advantages. First of all, they exhibit:

  1️⃣ 8% strain recovery – delivering up to 300% greater flexural endurance in steerable catheters
  2️⃣ Body-temperature activation (Af = 37 ± 2°C) – precisely customized for human physiology
  3️⃣ Nanofinished surfaces (Ra ≤ 0.05 μm) – significantly reducing fluid drag by up to 40%, thereby improving flow and accuracy

  Consequently, Nitinol tubing enables performance levels that conventional materials simply cannot match.

  Frequently Asked Questions (FAQs)

  Q1: Why use Nitinol tubes in medical devices?
  Nitinol combines shape memory with superelasticity, enabling both transient deployment and long-term structural integrity—ideal for implantable and flexible tools.

  Q2: How is fatigue resistance achieved?
  We use VAR-melted feedstock and a multi-stage cold-working process. Consequently, our tubes demonstrate fatigue life exceeding 10 million cycles.

  Q3: What are the lead times for custom sizes?
  Standard outer diameters ship within 72 hours. On the other hand, ultra-thin wall tubing (≤ 0.1 mm) requires 15 business days.

  Q4: Do you offer additional services?
  Yes. In addition to raw tubing supply, we provide laser cutting, shape-setting, and complete OEM component solutions.
