Importance of 0.2mm Wall Thickness Nitinol Tubing for Micro Catheters

Unique Properties of Nitinol

Nitinol is special because of its amazing traits. These make it great for medical tools like microcatheters. Its shape memory effect lets it return to its original shape after bending when heated. This helps devices stay useful even if twisted or bent. Another important trait is superelasticity, which lets nitinol bend a lot without breaking. This flexibility is key for moving through narrow blood vessels.

The table below shows nitinol's unique traits:

Property	Description
Shape Memory Effect	Goes back to its original shape when heated.
Superelasticity	Bends a lot and recovers without needing heat.
Biocompatibility	Safe for the body due to a protective titanium oxide layer.
Corrosion Resistance	Stays strong and resists damage in the body.
Fatigue Resistance	Handles repeated stress without wearing out.

These traits make 0.2mm wall thickness nitinol tubing reliable for tough conditions.

Role of Nitinol in Micro Catheter Design

Nitinol is very important in making microcatheters, especially with a 0.2mm wall thickness. Its strength and flexibility help the tubing fit into blood vessels easily. This makes it safer and easier to use. Nitinol is also lightweight but strong, which keeps the tubing durable.

Some design benefits include better visibility and easy adjustments. Radiopaque marker bands, added to nitinol microcatheters, help doctors place them accurately. Also, nitinol's superelasticity lets doctors move or adjust the catheter during procedures. This gives them more control.

The table below explains nitinol's role in microcatheter design:

Feature	Description
Material	Nitinol braiding adds strength and flexibility.
Design Benefit	Fits blood vessels for smoother movement.
Migration Minimization	Helps keep the catheter in place during use.
Visibility	Radiopaque markers make placement easier.
Repositioning Capability	Lets doctors adjust the catheter's position as needed.

These features make nitinol tubing with a 0.2mm wall thickness essential for top-quality microcatheters.

Dimensions and Specifications of 0.2mm Wall Thickness Nitinol Tubing

Inner Diameter, Outer Diameter, and Wall Thickness

Precision is key for 0.2mm wall thickness nitinol tubing. The outer diameter is 0.6mm, and the inner diameter is 0.4mm. These sizes give the tubing strength and flexibility. The 0.2mm wall thickness keeps it strong but bendable. This helps it move through narrow blood vessels easily.

These dimensions make the tubing perfect for microcatheters. The outer size works with many medical tools. The inner size allows guidewires or fluids to pass smoothly. Careful design improves how the tubing works in delicate medical tasks.

Length and Customization Options

The tubing length can change based on what’s needed. Standard lengths range from 10cm to over 150cm. This lets you pick the right size for short or long procedures.

Customization is another big benefit. Companies like AccuPath can make tubing to fit your needs. You can ask for specific lengths, sizes, or extra features like radiopaque markers. These markers help doctors see the tubing better during procedures. Custom options ensure the tubing fits your medical needs perfectly.

Manufacturing Tolerances and Standards

Making 0.2mm wall thickness nitinol tubing follows strict rules. Medical-grade tubing usually has a wall thickness between 0.1mm and 0.3mm. Sizes are kept accurate within ±0.01mm or better. This ensures top quality.

The table below shows size tolerances for outer diameters:

Outer Diameter (OD) Range mm	Tolerance mm
≤ 0.3	±0.005
0.3 ≤ OD ≤ 0.5	±0.007
0.5 ≤ OD ≤ 1.5	±0.015

Manufacturers must also follow strict safety rules. Standards like FDA 21 CFR Part 820 and ISO 13485 guide the process. Each batch is tested for safety, material quality, and sterilization. ASTM F2063 ensures nickel levels stay safe for patients.

These rules and tests make sure the tubing works well in medical use. Choosing trusted companies like AccuPath gives you safe and reliable tubing for your procedures.

Performance Implications of 0.2mm Wall Thickness
