Customized Pebax Medical Single Lumen Catheter with Drilling

Introduction to PEBAX Single-tube Drilling

Pebax medical perforated single tubes are single-lumen medical tubing made from medical-grade Pebax® (polyether block amide, PEBA) material through precision extrusion and perforation. They combine the strength of plastic with the elasticity of rubber and are widely used in medical scenarios such as minimally invasive intervention, drainage and irrigation, and drug delivery. They achieve functions such as liquid/gas exchange, drug release, or tissue anchoring through precise perforations in the tube wall.

Material:

Pebax® is a block copolymer of rigid polyamide (PA12) hard segments and flexible polyether soft segments. Medical grade (SA01MED) meets USP Class VI and ISO 10993 biocompatibility standards, and is free of plasticizers and allergens.

• Mechanical Properties: Wide hardness range of 25D-74D, high elastic memory, anti-kink and anti-bending, precise torque transmission, small change in internal modulus, and low hysteresis.

• Biosafety: Non-toxic, non-antigenic, non-carcinogenic/teratogenic, resistant to body fluid corrosion, and does not precipitate or adsorb.

• Processing Compatibility: Can be extruded into extremely fine tubes (inner diameter from 0.1mm), supports laser/ultrasonic drilling, and can be added for barium sulfate imaging.

• Sterilization Compatibility: Tolerates mainstream medical sterilization methods such as ethylene oxide and gamma rays.

Drilling process：

Laser drilling（Non-contact, small heat-affected zone, precise aperture (±25μm), and round aperture shape）.

Typical application scenarios of PEBAX medical single-tube punching

Interventional treatment: balloon dilation catheter (irrigation port), angiography catheter (side-port angiography), guiding catheter (irrigation port).

Drainage systems: ventricular drainage tube, chest drainage tube, abdominal drainage tube (multi-port anti-blockage).

Drug delivery: local anesthesia catheters, pain management catheters, drug elution catheters (precision controlled release).

Other: Dialysis catheters, endoscopic instrument access tubes, minimally invasive surgical aids.

PEBAX Medical Single-lumen Tube Core Advantages

• Performance balance: Combining rigidity and flexibility, pushing ability and compliance, suitable for complex anatomical pathways (such as cardiovascular and neurovascular pathways).

• Precise Functionality: Uniform and controllable orifice opening ensures stable drainage/infusion flow and predictable drug release rate.

• Safe and reliable: Excellent biocompatibility, reducing the risk of tissue irritation and thrombosis, and resistant to bending and clogging.

• Durable and long-lasting: Resistant to chemical corrosion and repeated bending, stable internal and external properties, and long shelf life.
