What is 14Fr PEBAX 7233 Medical Sheath Catheter Semi-Finished？

This 14Fr medical introducer sheath semi-finished product is precision extruded from medical-grade PEBAX 7233 resin, completed with three core post-processing techniques: laser scale marking, proximal flared hub forming, and distal bevel cutting. It serves as a critical foundational component for manufacturing interventional, minimally invasive surgical, and drainage medical devices.

As an unsterilized, uncertified industrial-grade semi-finished product, it is exclusively designed for medical device manufacturers with valid production qualifications and certification capabilities. It can be directly used for subsequent assembly, sterilization, and regulatory compliance processes, significantly shortening product development cycles and reducing production costs.

We offer full customization services for all dimensions and processes, allowing adjustments to tube diameter, length, scale style, and tip structure based on your clinical requirements to meet personalized application needs across different surgical scenarios.

Core Specifications

Three Core Post-Processing Techniques

1. High-Precision UV Laser Scale Marking

Medical-grade UV laser etching technology is used to create clear, permanent scales on the tube surface with a depth of 10-20μm. The markings are abrasion-resistant, chemical-resistant, and will never peel off, eliminating clinical risks associated with ink shedding from traditional screen printing. Scales are evenly distributed from 1cm to 10cm, with numerical markings every 1cm and short tick marks every 1mm, enabling accurate insertion depth judgment during surgery and improving procedural accuracy and safety.

2. Proximal Flared Hub Forming

The proximal end of the tube is processed into a standard flared hub structure using precision thermal forming technology. The flared edge is smooth without burrs or flash, with a uniform inner diameter transition. This design significantly reduces insertion resistance for guidewires, balloon catheters, and other interventional instruments, prevents instrument jamming or tube deformation, and facilitates quick connection to syringes, negative pressure devices, and other supporting equipment.

3. Distal 45° Bevel-Cut Tip

The distal end of the tube is cut into a 45° bevel using CNC precision cutting technology, and the tip is polished to a rounded, sharp-free finish. The beveled tip effectively minimizes tissue damage during puncture, reduces patient bleeding and infection risks, and improves sheath deliverability through blood vessels, body cavities, and soft tissues, allowing surgeons to quickly establish surgical access.

Key Advantages of PEBAX 7233 Material

PEBAX 7233 is one of the most widely used high-performance thermoplastic elastomers in interventional medical devices, offering unmatched comprehensive performance compared to traditional PVC, TPU, and nylon materials:

• Excellent balance of rigidity and flexibility: 72D high hardness ensures sufficient support to maintain lumen patency without collapse, while retaining excellent flexibility to conform to natural body cavity curvatures

• Superior kink resistance and fatigue durability: Resists permanent deformation or fracture after repeated bending, ideal for procedures involving complex anatomical structures

• Low friction coefficient: Smooth inner and outer surfaces significantly reduce instrument delivery resistance and tissue friction damage

• Outstanding biocompatibility: Non-cytotoxic and non-sensitizing, safe for contact with human tissues and blood

• Excellent chemical resistance: Tolerates common disinfectants such as alcohol and iodine, and is compatible with most clinical medications

• High processability: Supports extrusion, injection molding, thermoforming, and welding, enabling complex structural designs

Typical Applications

This 14Fr PEBAX 7233 introducer sheath semi-finished product is widely used in the manufacturing of various minimally invasive interventional surgical instruments, including:

• Vascular access sheaths (femoral artery sheaths, radial artery sheaths, venous sheaths)

• Non-vascular drainage sheaths (thoracic drainage, abdominal drainage, abscess drainage)

• Endoscopic surgical working channel sheaths

• Guidewire protectors and instrument protective sleeves

• Custom medical catheter prototype development and small-batch trial production

• Interventional device R&D for animal experiments
