En médecine interventionnelle moderne mini-invasive, Micro-cathéter sont devenus un outil essentiel permettant aux médecins d’accéder aux minuscules vaisseaux sanguins et cavités du corps humain pour un traitement précis. Étant donné que leur diamètre extérieur est généralement inférieur à 1 mm, le fonctionnement de ces dispositifs médicaux de haute précision nécessite des compétences professionnelles extrêmement élevées et une compréhension approfondie du produit.| I. Procédures opératoires et techniques de base pour le micro-cathéter Les microcathéters sont conçus pour atteindre des sites complexes tels que les nerfs et les vaisseaux sanguins. Voici les étapes clés de l’utilisation clinique : Préparation et rinçage Avant utilisation, la lumière du microcathéter doit être soigneusement rincée avec une solution saline héparinée pour éliminer l'air et activer le revêtement hydrophile interne, réduisant ainsi la friction. Fixation du fil de guidage Les microcathéters sont généralement utilisés conjointement avec des fils microguides en utilisant une « technique coaxiale ». Le fil microguide est inséré dans le cathéter et le guidage directionnel de la pointe du fil guide aide le microcathéter à passer en douceur à travers les vaisseaux sanguins tortueux. Pousser et suivre Tirant parti de la flexibilité et de la maniabilité supérieures du cathéter, le médecin le pousse lentement vers la zone de lésion cible sous la surveillance d'une fluoroscopie à fluorescence X. Administration précise du médicament ou placement du stent Une fois que le microcathéter atteint l'emplacement désigné, il peut être utilisé pour administrer des matériaux emboliques, des médicaments de chimiothérapie ou servir de canal pour les systèmes de pose de stents.

In the design and manufacturing of minimally invasive medical devices, the choice of catheter material directly determines the product's performance and clinical safety. Medical PI tubing (polyimide tubing) and medical PTFE tubing (polytetrafluoroethylene tubing) are currently the two most widely used high-performance polymer materials in interventional medicine. Although both possess excellent biocompatibility, they differ significantly in mechanical properties, processing techniques, and specific applications. As a professional supplier of medical-grade tubing, LINSTANT is committed to providing high-performance material solutions for global medical device development. Our business scope covers a comprehensive product line from basic extrusion to complex reinforced structures, including extruded single/multilayer tubing of various sizes, single-lumen/lumen tubing, single/double/triple-layer balloon tubing, coil/braided reinforced sheaths, as well as specialty engineering materials PEEK/PI tubing and various surface treatment solutions. I. Comparison of Core Material Properties To understand the differences between the two, we must first start with their physical and chemical properties: 1. Medical PI Tube (Polyimide) Medical PI tubes are renowned for their extremely high strength and extremely thin wall thickness: High Strength and Hardness: PI material has extremely high tensile strength, providing excellent compressive strength and kink resistance. Extremely Thin Wall Thickness: It can be processed into micro-tubes with a wall thickness of only about 0.01mm, which is crucial for interventional procedures requiring passage through extremely fine blood vessels. High Temperature Resistance and Chemical Stability: It maintains structural stability under various sterilization environments. 2. Medical PTFE Tube (Polytetrafluoroethylene) PTFE is known worldwide for its "slippery" properties, being one of the solid materials with the lowest coefficient of friction: Extremely High Lubricity: The ultra-low friction of the inner surface of Medical PTFE Tube makes it an ideal choice for guide wires and liners in delivery systems. Excellent Flexibility: Compared to medical PI tubes, PTFE is more flexible and easier to bend. Non-stickiness: It adheres to virtually no substances, effectively preventing thrombosis. II. Main Differences Between Medical PTFE Tubes and Medical PI Tubes Physical Strength and Support: Medical PI tubes possess extremely high tensile strength and rigidity, exhibiting metal-like physical properties, providing excellent resistance to kinking and structural support. In contrast, Medical PTFE Tube products are softer and more flexible, but are prone to deformation under pressure. Wall Thickness and Dimensional Accuracy: In interventional medical devices requiring extremely miniaturization, medical PI tubes offer significant advantages. They can be processed into extremely thin tubes with a wall thickness of less than 0.02 mm while maintaining strength. Medical PTFE tubes, due to material limitations, typically have thicker walls, making it difficult to achieve the same level of strength in ultra-thin specifications. Surface Friction and Lubrication: Medical PTFE tubes possess the lowest known coefficient of friction among solid materials, exhibiting natural super-slippery properties, making them ideal as liners for delivery systems. While medical PI tubes have a smooth surface, their friction is relatively high, usually requiring the application of a hydrophilic coating to improve their slipperiness. Bonding and Composite Processing Capabilities: Medical PI tubing has good chemical polarity, making it easy to bond and composite with medical adhesives (such as UV adhesives) or thermoplastic elastomers (such as Pebax); Medical PTFE Tube tubing, on the other hand, has extremely strong non-adhesive properties and usually requires complex sodium curing treatment or LINSTANT's PTFE surface treatment before being composited with other materials. Visual Characteristics and Transparency: Medical PI tubing typically exhibits a characteristic amber, golden yellow, or dark brown color; while medical PTFE tubing usually appears as an opaque milky white or translucent waxy appearance. III. Differences in Clinical Application Scenarios Due to their different properties, these two types of medical catheters play different roles in interventional medical devices: Applications of Medical PI Tubing Due to its excellent electrical insulation properties and rigidity, it is often used as a reinforcing layer for electrophysiological catheters, microcatheters, and as a support cannula in cardiovascular interventional devices. When it is necessary to pass through narrowed lesions, the pushing force provided by medical PI tubing is unmatched by other materials. Applications of Medical PTFE Tubing Primarily used as a catheter liner. In multilayer composite catheters, PTFE, as the innermost layer, ensures smooth passage of guidewires or other instruments through the catheter lumen, reducing operational resistance. IV. How to Choose the Right Catheter Material for Your Needs? During the development process, the choice between medical PI tubing and PTFE tubing depends on your design goals: If your device requires an extremely small outer diameter and a very large inner diameter (i.e., thin-walled), while also demanding extremely strong support, medical PI tubing is the preferred choice. If the core requirement of your device is smooth delivery of internal instruments, then a PTFE liner is indispensable. Composite Solutions: Modern high-end microcatheters typically employ a "combination of inner and outer layers." LINSTANT can provide customized coil/braided reinforced sheaths, perfectly integrating PTFE liners with medical PI tubing or other reinforcing layers. LINSTANT consistently focuses on the cutting-edge needs of minimally invasive medicine, helping medical device manufacturers achieve more precise and safer clinical procedures by providing precision-engineered PEEK/PI tubing and multilayer/multi-lumen tubing.

PEEK tubing (polyether ether ketone tubing) is highly favored in laboratory analysis, medical device manufacturing, and aerospace engineering due to its exceptional performance. This high-performance polymer can withstand high temperatures up to 250°C (and even 260°C for short periods) and possesses excellent chemical stability and mechanical properties. However, due to the hardness and high toughness of PEEK material, achieving precise and smooth cuts presents a challenge for many engineers. Why is the Cutting Quality of PEEK Tubing Important? Whether used in high-performance liquid chromatography (HPLC), precision medical catheters, or military aerospace applications, the cutting quality of PEEK tubing directly impacts its effectiveness: Reduced dead volume: In analytical instruments, uneven cuts can lead to dead volume at the connection points, causing signal peak broadening or experimental errors. Ensured sealing: Vertical and smooth cuts ensure a tight seal between the tubing and connectors, preventing leaks under high-pressure conditions. Maintaining biocompatibility: Professional cutting methods prevent the generation of debris, ensuring the biocompatibility of PEEK tubing in medical applications (such as cardiovascular, spinal surgery, and endoscopy). Common PEEK Tubing Cutting Methods and Professional Equipment 1. Using a Dedicated Tube Cutter (Preferred for Laboratories) Dedicated tube cutters are usually equipped with a V-groove to securely hold the PEEK tubing, ensuring the blade cuts perpendicularly. Operating tips: Apply even pressure during cutting and avoid rotating the tube to prevent spiral patterns on the cut surface. 2. Automated Precision Extrusion and Cutting (Preferred for Industrial Applications) For large-scale production, more advanced facilities are required. LINSTANT has nearly 20,000 square meters of cleanroom space, fully compliant with GMP requirements. We are equipped with 8 dedicated PEEK extrusion production lines, capable of producing tubing with high strength, high fracture toughness, and dimensional stability. With 40 sets of welding and molding equipment, we can achieve precise length control and end-face treatment directly in the production process, ensuring that every inch of PEEK tubing meets stringent standards. 3. Laser Cutting Technology For extremely fine or complex-shaped medical catheters (such as urological catheters and electrosurgical forceps sheaths), laser cutting offers non-contact, ultra-high precision. About LINSTANT: Your High-Performance Tubing Partner When addressing the application challenges of PEEK tubing, choosing a supplier with strong production capabilities is crucial.

Precautions During the Cutting Process When handling PEEK tubing, its material characteristics should be fully considered: Avoid using ordinary scissors: Ordinary scissors will compress the tube wall, causing deformation and oval-shaped cuts that severely affect fluid flow. Maintain cleanliness: As PEEK is often used in trauma care and orthopedic surgery, the cutting environment and tools should be kept clean to avoid cross-contamination. Pay attention to dimensional stability: Although PEEK has excellent dimensional stability, extra care is required when cutting extremely thin-walled tubes to prevent collapse. Correctly cutting PEEK tubing is the crucial first step in leveraging its high-temperature resistance, wear resistance, and flame-retardant properties. Whether you need precise cutting of a single tube or are looking for a large-scale customized production partner, LINSTANT can provide professional support that meets GMP standards. Avoid using ordinary scissors for cutting, as this will damage the roundness of the PEEK tube.
