Medical PP Uterine Catheter Semi-Finished (Tip Forming + Bend Shaping) - Professional Custom Manufacturer

Product Overview

Core Processes and Product Advantages

1. Medical Grade PP Material Properties

• Excellent biocompatibility: Complies with ISO 10993 biocompatibility standards, non-cytotoxic, non-sensitizing, non-hemolytic, and safe for contact with human mucosal tissues

• Strong chemical stability: Resistant to corrosion by most medical disinfectants, does not react with intrauterine drugs, ensuring the accuracy of drug delivery in finished products

• Ideal mechanical properties: Combines good rigidity and flexibility, pushes smoothly without kinking, while maintaining lumen patency and effectively avoiding blockage

• Optional X-ray visibility: Medical grade contrast agent can be added to achieve real-time imaging positioning during surgery, improving the operational safety of finished devices

• Good processing adaptability: High surface finish, easy for secondary processing such as connector welding, printing and coating

2. Precision Tip Forming Process

• Completely eliminates burrs and sharp edges at the tube end, minimizing mechanical damage to cervical mucosa and endometrium during use of finished devices

• Seamless transition between tip and tube body, no steps or depressions, avoiding tissue scraping and bacterial residue

• Precisely controls tip diameter, length and radian to adapt to different cervical os sizes and finished product design requirements

• Customizable tip hardness to balance insertion guidance and tissue protection

3. Precise Bend Shaping Process

• Bend angle can be precisely customized within 15°-90° with tolerance controlled within ±2°

• No wrinkles, no collapse, no wall thinning at the bend, maintaining the cross-sectional area of the lumen

• Stable bend angle after shaping, no springback deformation under clinical use temperature and pressure

• Multi-segment bend structure can be designed to perfectly fit the physiological curvature of female reproductive tract and reduce patient discomfort
