Longitudinal Change: Refers to the percentage change in length after heating. To ensure the precision of instrument assembly, high-quality products require this indicator to be controlled within ±5%. Biocompatibility: The material must pass relevant biological evaluations to ensure safety when in contact with human tissue. Wall Thickness: With the trend towards miniaturization of interventional devices, ultra-thin wall technology can now reduce thickness to less than 0.005mm. Understanding the different types of medical heat shrink tubing can help R&D personnel select the most suitable solution during the initial product design phase. Whether pursuing extreme lubrication or ultra-thin walls, choose a partner like LINSTANT with a strong GMP manufacturing background and co-extrusion technology capabilities.

In the development of minimally invasive medical devices, the choice of liner material directly determines the success of the procedure. PI tubing (polyimide tubing) and PTFE tubing have always been core components of high-performance catheters. Key conclusion: If extremely thin wall thickness, excellent torque transmission, and kink resistance are required, medical-grade PI tubing is the best choice; if ultimate lubricity is needed, PTFE offers advantages. As a professional manufacturer deeply rooted in the field of interventional medical consumables, our business scope covers the entire range of medical-grade PI tubing solutions, from basic materials to complex structures, dedicated to solving material challenges for medical device engineers worldwide. In-depth Comparison of Key Performance Characteristics of Medical-Grade PI and PTFE Tubing Before deciding which material to choose, we recommend a thorough evaluation of PI and PTFE tubing based on the following four core dimensions: Wall Thickness Limit and Space Efficiency This is the core strength of medical-grade PI tubing. It can achieve extremely thin wall thicknesses (as low as 0.0005 inches) while maintaining extremely high strength. Compared to the susceptibility of PTFE to deformation at thin wall thicknesses, PI tubing significantly optimizes the inner diameter (ID) space of the catheter. We provide extruded single-layer/multi-layer tubing, which can be precisely customized according to requirements, helping devices achieve miniaturization. Mechanical Strength and Structural Support PI tubing has extremely high tensile strength. For catheters that need to navigate tortuous blood vessels, our spiral/braided reinforcement sheath technology maximizes the physical properties of medical-grade PI tubing, ensuring excellent torque response. Coefficient of Friction and Surface Treatment Although PTFE has better inherent lubricity, we can effectively improve the smoothness of PI tubing through various surface treatment solutions, making it possess both strength and passability, meeting the clinical needs of various single-lumen/multi-lumen tubing. Stability under Complex Conditions In high-temperature or high-pressure environments, special engineering materials such as PEEK/PI tubing exhibit superior dimensional stability compared to PTFE, especially in the manufacturing process of single-layer/double-layer/triple-layer balloon catheters, providing more reliable support.

Flaring or tipping medical PEEK Tubing is primarily achieved through precision thermal processing. Due to PEEK's (polyether ether ketone) extremely high melting point (approximately 343°C), traditional cold working methods cannot permanently deform it. The typical process involves placing the catheter end in a precisely temperature-controlled induction heating coil. Once the material reaches its softening point, a precision mandrel or mold is used to physically extrude and shape it. As a professional medical device component partner, LINSTANT, with its advanced production facilities, ensures that every medical PEEK Tubing catheter maintains excellent biocompatibility and mechanical strength after shaping. Why are the forming processes for medical PEEK Tubing so demanding? In the medical device manufacturing field, medical PEEK Tubing are known for their excellent strength-to-weight ratio and chemical inertness. However, achieving perfect secondary processing (such as flaring or welding) requires stringent requirements on the original extrusion quality of the tubing. LINSTANT has nearly 20,000 square meters of cleanroom space, fully compliant with GMP requirements. We understand that even the slightest dust particle or impurity can lead to cracks during the thermoforming process. Through eight dedicated PEEK extrusion production lines, we can provide global customers with dimensionally stable, highly pure, high-performance tubing, addressing the pain points of carbonization and brittleness during the forming process. Core Technical Steps in Medical PEEK Catheter Forming In the design of cardiovascular intervention or endoscopic instruments, the following fine processing of medical PEEK Tubing is usually required: 1. Mold Forming (Tipping & Flaring) Flaring: Expanding the end of the tubing for connection with Luer connectors. Tipping: Shaping the end of the tubing into a rounded bullet shape to reduce trauma when entering the human body. 2. Integrated Reinforcement Technology For complex medical device designs, LINSTANT's 40 sets of welding and molding equipment and nearly 100 sets of weaving/spring equipment can be used in conjunction with PEEK tubing.

In interventional procedures, guiding catheters are vital "lifelines" connecting the external system to the lesion site. To achieve precise positioning and support in complex vascular pathways, high-quality guiding catheters commonly employ a sophisticated braiding process. As a leader in this field, LINSTANT leverages its deep manufacturing expertise to provide high-performance catheter solutions to customers worldwide. Why do guiding catheters need a braided wire structure? A guiding catheter is more than just a plastic tube; its internal structure determines the success of the procedure. The braided layer, typically located in the middle of the catheter wall, provides the catheter with the following core properties: Superior flexural strength and stability: The braided structure ensures the catheter is less prone to flexing in tortuous blood vessels, maintaining lumen patency. Higher torque control: When the surgeon rotates the catheter externally, the braided layer transmits force 1:1 to the distal end. Maneuverability and maneuverability: The braided layer provides the necessary longitudinal strength, making the catheter more maneuverable in complex interventional pathways. Features of High-Quality Guiding Catheters Whether standard models or customized OEM guiding catheters, a high-performance catheter needs to meet multiple clinical requirements for flexibility, support, and patency. LINSTANT guiding catheters possess the following core technological advantages: Multi-Level Hardness Design: A multi-level design with varying hardness levels enhances the catheter's flexibility. Tip Softening: A soft tip reduces damage to blood vessels and tissues. Optimized Braided Structure: A precise braided structure provides higher torque, stability, and maneuverability. Ultra-Thin Wall, Large Lumen: Ultra-thin walls combined with a large internal cavity facilitate the passage of complex instruments.
