Asahi Intecc Co., Ltd. is a Japanese medical device manufacturer specialized in making flexible cables and tubes with high torsional rigidity. Besides single cable and tube components, we also offer full coating- and assembly services. Drawing from our vast experience in the medical device field, our in-house wiredrawing, wire-forming, coating, torque and assembly technologies provide a broad range of options for your device.

Single Lumen Tubing

Asahi Intecc custom extrudes thermoplastic and fluoropolymer single lumen tubing in FEP (fluorinated ethylene propylene), PTFE, PFA, PE (polyethylene), NYLON, PEBAX (polyether block amide), TPU, PU (polyurethane) and PP. For size and wall thickness range of each material, please contact us for further information. Tubing can be provided on a spool or precision cut lengths.

Polymer Extrusion Concentricity and Surface Conditions

Manufacturing in an ISO 13485 approved 100,000 Clean Room environment, Asahi Intecc offers the highest level of consistent concentricity for single-lumen extrusions. A polymer tube's concentricity results in stronger resistance to burst pressure and ease to assemble other parts. Concentricity of our extruded polymer shafts naturally results in a consistently superior appearance, compared to the often eccentric shapes of other polymer tubings in the global marketplace. Along with concentricity for extrusions is our attention to polymer surface conditions which are free of gels and melt fractures. As Asahi Intecc has in-house polymer compounding capabilities with a choice of small size and middle size twin screw extruders, we can choose the equipment and the conditions to optimize the concentricity and surface conditions of our polymer extrusions.

Variable Flexibility Tubing

This tubing may be used where a proximal push and rotation along with a delicately flexible distal tip is desirable to access the treatment area. Offered on our catheters and as part of our OEM/ODM and assembly services, the multi-segmented flexibility is seamless without manually connecting joints between the two selected materials with different Shore hardness grades.

Thin Wall Tubing

Thin wall polymer tubing is offered in PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxy), PE, and ETFE (ethylenetetrafluoroethylene). Thin-wall tubes can be custom manufactured for multi-layer tubing and braided tubing, and often as inner liners for our 1-1 torque stainless hollow shafts. For details with your challenging delivery system, material, mechanical, chemical, and dimensional requirements, please contact us.

Custom Compounding Service

Asahi Intecc offers to medical tubing manufacturers and polymer processors a compounding service in materials of FEP, PTFE, PFA, PE (HDPE - high density polyethylene, LDPE - low density polyethylene), NYLON, (Grilamid, Polyamide, Polyamide Elastomer, PEBAX) TPU, PP (polypropylene), in small, affordable quantities and short lead-times. Small lots (5kg) with excellent consistency and dispersion may be blended or pelletized in a wide range of colors. Contrast media options include bismuth trioxide Bi2O3, barium sulphate (BaSO4), bismuth sub carbonate (BiO)₂CO₃ are available for applications which are viewed under fluoroscopy.

PTFE Over the Mandrel

Provided on a spool, PTFE is coated on the mandrel by a dipping process.The mandrel size ranges from 0.45mm to 2.30mm. The PTFE wall thickness (one side can range from 0.008mm to 0.012mm (0.00031" to 0.00047" or 8 to 12 microns).The PTFE is chemically etched on catheter delivery systems, microcatheters, and other delivery systems, where an instrument or a guidewire passes through a PTFE coated lumen.

Multi-Layer Tubing – Polymer and Braided Reinforcement (Nylon, Tungsten, Stainless)

Nylon, tungsten, or stainless braid can be braided over a lubricious, low-friction, drug-resistant PTFE liner with a silver mandrel to provide torque response, kink and fluid pressure resistance (saline, blood, drug, chemical, nutrient). Pitch and pick count may be adjusted on the braid for customized flexibility, kink-resistance, and torque properties.

Mandrel + PTFE Thin Wall Tube+Braiding

Stainless braid for catheter shafts and Nylon braid for catheter shafts

Mandrel + PTFE thin wall tube +braiding is provided on spool.

These are components for Micro Catheters and Guiding Catheters.

ACTONE Cable Tube with Inner Tube (PTFE, PE, ETFE, PEBAX) or Outer Extrusion

Fully extruded torque assemblies with ACTONE CABLE TUBE with high performance PTFE or ETFE inner liners. Inner tubing may be attached by adhesive bonding on both ends, depending on the wall thickness, flexibility, and 1-1 torque requirements.

ASAHI Components Plus Inside Outside Coating

Asahi Intecc offers extrusion, dip coat, and heat shrink (1mm to 1.6mm recovered ID in PTFE or FEP) solutions for customers developing delivery systems with drive cables, ACT-ONE Cable tubes and torque coils to improve lubricity or sealing with high bonding strength. Customers can enjoy a more consolidated supply base with excellent in-house expertise in both metal and polymer solutions.
