4-Wire Nitinol Stone Retrieval Basket

4-Wire Nitinol Stone Retrieval Basket Specifications

The 1×4×0.2 mm configuration refers to a four-wire Nitinol structure using 0.2 mm Nitinol wire. Other wire diameters, lengths, basket sizes, and configurations can be discussed according to the final device design.

Why Use Nitinol for Stone Retrieval Baskets?

Nitinol is widely used in minimally invasive medical devices because of its unique combination of flexibility, superelasticity, and shape memory properties.

For stone retrieval applications, these characteristics can help the basket achieve controlled deformation and recovery during deployment and retrieval.

Superelasticity

Superelastic Nitinol can undergo significant deformation and recover toward its original configuration after the external force is released.

This property is particularly useful for a retrieval basket that needs to pass through a narrow delivery system and then expand into its working configuration.

Excellent Flexibility

Nitinol wire can provide the flexibility required for minimally invasive medical devices.

The 0.2 mm wire diameter provides a compact structure while maintaining the mechanical characteristics required for basket formation.

Shape Recovery

Through appropriate heat treatment and shape setting, Nitinol wires can be formed into a predetermined basket geometry.

After deformation, the basket can recover toward its programmed configuration.

Compact Structure

A four-wire basket design provides a relatively simple and compact structure for stone capture and retrieval.

The wire configuration, basket diameter, length, opening size, and tip design can be customized according to the intended application.

1×4×0.2 mm Nitinol Wire Configuration

The standard configuration of this product is 1×4×0.2 mm.

In this configuration, four Nitinol wires with a nominal diameter of 0.2 mm are formed into a retrieval basket structure.

The final basket geometry can be adjusted according to the customer’s requirements, including:

• Basket diameter
• Basket length
• Wire length
• Opening size
• Tip configuration
• Connection structure
• Heat-setting shape
• Surface condition

For OEM medical device projects, customers can provide drawings or technical specifications for evaluation.

Custom Nitinol Stone Retrieval Basket

Medical device designs often require different basket dimensions depending on the target application.

Haolu Tech can customize Nitinol retrieval basket components according to customer drawings and specifications.

Customization options include:

Custom Wire Diameter

Besides the standard 0.2 mm Nitinol wire, other wire diameters can be evaluated according to the required flexibility and mechanical performance.

Custom Basket Dimensions

Basket diameter and length can be adjusted according to the required working range and device structure.

Custom Shape Setting

Nitinol wires can be heat-set into the required basket configuration.

The shape-setting process is controlled according to the material condition, wire geometry, and required final shape.

Custom Surface Treatment

Different surface conditions can be supplied depending on the application, including clean, bright, ground, or oxidized surfaces.

For medical applications, surface requirements should be confirmed before production.

Manufacturing Process of Nitinol Retrieval Baskets

The manufacturing process of a Nitinol stone retrieval basket generally involves several precision processing steps.

1. Nitinol Wire Preparation

Nitinol wire with the required diameter and material condition is selected according to the basket design.

2. Wire Forming

The Nitinol wires are arranged and formed into the required four-wire basket configuration.

3. Shape Setting

The basket is fixed in the required geometry and heat-treated to establish its programmed shape.

Typical Nitinol shape-setting temperatures are approximately 400–550°C, with the actual parameters determined according to the material and product design.

4. Surface Treatment

After forming and heat treatment, appropriate surface processing can be performed according to the customer’s requirements.

5. Inspection

The finished component can be inspected for dimensional accuracy, appearance, and other specified requirements.

Material and inspection documentation can also be provided according to the project requirements.

Applications

The 4-wire Nitinol stone retrieval basket can be used as a component in minimally invasive stone retrieval devices.

Potential applications include:

• Urological stone retrieval devices
• Endoscopic stone retrieval systems
• Minimally invasive surgical instruments
• Stone capture baskets
• Medical retrieval devices
• Custom endoscopic instruments

The final application and clinical use of the finished device depend on the customer’s complete medical-device design, regulatory requirements, and validation process.
