Our products

Product category: Braided tubings


MicroLumen offers custom braid and coil reinforced PTFE and polyimide tube shafts. Primary advantages of using PTFE and polyimide tubing include increased column strength, torque transmission and increased burst strength. Reinforced PTFE and polyimide tubes are available in a wide range of diameters and configurations. The construction of a typical reinforced tube consists of a substrate layer, a braided or coiled layer, and an exterior layer. Substrates can include Polyimide, PTFE Composites, or Pure PTFE liners. Pure PTFE liners and PTFE Composites offer reduced surface friction. The exterior layer is typically constructed of Polyimide, but can consist of thermoplastics like Pebax®, Nylon & Urethanes for varying durometer & color.
Steel Coil Reinforced PTFE and Polyimide Tubing Specifications
The most common braid/coil material is 304V stainless steel.
Both round and flat wires are available. Common wire sizes:
Round wire 0.0010" to 0.0020"
Flat wire 0.0005" x 0.0025" and larger
"PIC" count = per inch crosses (Braid)
"WPI" count = wraps per inch (Coil)
Higher PIC counts improve flexibility, while a lower PIC count increases longitudinal stiffness
The PIC count can be varied within a specific length to provide variable flexibility (this can also be achieved via selective laser removal of OD layers)
Selective laser removal of Polyimide top-layers increases flexibility and helps in secondary processes & assembly
Coil reinforced designs offer better overall flexibility
Axial reinforcement provides added tensile strength and minimized elongation
Band swaging facilitates visualization during clinical use

PTFE Liners
Our PTFE tubing expands the capability of our medical tubing, allowing us to combine physical properties of multiple materials into one high-performance product. PTFE has one of the lowest coefficients of friction against any solid.
Our liners are typically built with a thickness at 0.00075" +/- 0.00025".
We can supply tubing with the PTFE liner or provide an etched OD PTFE on a mandrel for catheter building at your facility.
ETO sterilization is required with PTFE liners.
PTFE Composites
Our unique process of incorporating fluoropolymers with Polyimide provides excellent mechanical properties while reducing the coefficient of friction.
PTFE Composite Tubing can withstand gamma and e-beam sterilization.
Coefficient of Friction
Both PTFE composites and ultra-thin PTFE liners reduce the coefficient of friction:
Coefficient of friction:

Pure PTFE = 0.1
PTFE composite = 0.3
Polyimide = 0.5

Polyimide is a polymer thermoset plastic that has exceptional thermal stability, chemical resistance, and tensile strength. These characteristics make polyimide an ideal material for high-performance surgical and medical tubing applications. The tubing is lightweight, flexible, and resistant to heat and chemical interaction. Surgical tubing requires the high quality physical properties of polyimide to make it possible to achieve thin walls, tight tolerances, low friction, transparency, stiffness, and strength.

Cardiovascular catheters
Urological retrieval devices
Neurological applications
Fiber optics
Intravascular drug delivery
Balloon angioplasty & stent delivery

Sub-Assembly / Composites
MicroLumen medical tubing products offer a tremendous range of options to address the most complex medical tasks. Sub-assemblies and composites allow us to provide the multi-functionality you want in a product that is still minimally invasive, repeatable and reproducible. Sub-assemblies reduce your number of suppliers and can increase the speed to market. The most common thermoplastic materials used are Pebax®, Nylon and Urethanes. Our value-added sub-assemblies offer:

Variable flexibility throughout the length of the shaft via multi-durometer constructions
Combining different materials within a tube can optimize performance
Marker bands embedded for radiopacity
A-traumatic tips
Tapered and flared tube ends
Multi-lumen profiles
