# Extrusion Technology
## Medical Extrusion Technology
One Medical Extrusion’s technical and engineering expertise provides with the skills to extrude a wide range of materials, diameters, thicknesses, and tolerances.  This allows us to offer a custom extrusion solution specific to your extrusion requirements.
We offer a comprehensive range of extrusion processes including the following:
* Single Lumen
* Multi-Lumen
* Profile Tubing
* Multi-Layer
* Thin Wall Tubing
* Co-Extrusion
* Balloon Tubing
* Spooled
* Over Core
* Taper (Bump)
### Single Lumen & Microbore
* Diameters ranging from 0.003” to 0.450” & tolerance for most polymers and sizes: ± 0.0003″
* Wall thickness ranging from 0.0005” to 0.035″ & tolerance for most polymers and sizes: ±0.0003″
* Tolerances may vary depending on the durometer, material, and size of the extrusion
* Discrete lengths or spools available
* In-house die design and fabrication
* Internal annealing advanced measurement systems
* Critical visual inspection for implantable extrusions
### Multi-Lumen Tubing
Our team will work with you to develop and produce customized multi-lumen tubing to meet your specific requirements such as lumen geometry, material, and lumen rating. All extrusion tools required are designed in-house by our core design team. Our multi-lumen tubing is often used in demanding applications such as minimally invasive surgery where lumens allow multiple functions or instruments to be placed within a limited space.
Our multi-lumen tubing allows you to achieve the best possible flow rates and customizable configurations are unlimited. Your final configuration will be specific to your needs, and all aspects will be kept confidential for each customer.
### Balloon Tubing
In order to manufacture high-quality balloons, you must start with high-quality balloon tubing. We produce tubing with consistent wall thickness and excellent concentricity. Plus, we have the extrusion expertise to hold tight tolerances and control mechanical properties, such as elongation.
Materials:
* Grilamid® and Vestamid®
* Thermoplastic elastomers, such as Pebax®
* Thermoplastic Urethanes, such as Pellethane®
Size Range:
* OD ranges from 0.2mm (.007”) to 11.43 mm (.450”) and tolerances as low as +/-0.0127mm (0.0005”).
* Concentricity: >90% depending on size
### Multi-Layer (Co-extrusion & Trilayer) Tubing
A tri-layer extrusion is a single-lumen tube comprised of three discrete layers. Our team designs and manufactures a wide range of three-layer material combinations. These combinations can include, but are not limited to:
* Pebax
* Polyurethane
* Polyethylene
* Tie-Layer Material
* Blends
* Multi-layered medical tubing
Tri-layer structure allows the extrusion to have unique characteristics throughout the tube:
* Lubricious ID: Inner layer material having a low coefficient of friction.
* Lubricious OD: Outer layer material having a low coefficient of friction.
* Physical Properties: Layer materials can be tailored to increase burst strength, decrease elongation or improve tensile strength.
* Bendability: Outer layer material that allows for bonding to other polymeric materials or ink.
* Tri-Layer: Tri-layer tubing provides two non-compatible materials with the ability to bond together.
* Encapsulation: Encapsulate a radiopaque or filled resin between two unfilled resin layers.
* Tri-Layer Bump Tubing: Allows two individual outer and inner diameters within the same tubing.
OD sizes typically range from 0.4mm to 4mm.
Typical tolerance +/- 0.015mm. As material changes so can tolerances.
Typical testing: Tensile, elongation, burst pressure, wall measurement, and delamination are all available on-site.
### Solid Rod/Mandrel Extrusions
Solid rod thermoplastic extrusions are used as mandrels to assist in the reprocessing of catheters, as push rods, and to deploy implantable devices in catheter shafts, among other applications.
We can produce custom solid plastic rod extrusions in numerous configurations, including crescent or half-moon shapes, tapered plastic mandrels, and square profiles. We can manufacture solid plastic rod extrusions from a wide range of materials, including HDPE, Nylon, and other high-lubricity thermoplastics that aid in the removal of plastic mandrel devices.
# Catheter Technology
## Braiding
We can provide you with braided catheter solutions as a sub-assembly thereby enabling you to benefit from our expertise in braiding technologies.
From braid-on coil, multi-lumen, and stepped shaft catheter systems, we can deliver a custom-made design for your project’s needs.
We offer high-quality braided medical tubing, that can be customized to fit your design needs. We frequently work with flat and round stainless-steel wire in addition to monofilaments. Regardless of your requirements—be it torque control, kink resistance, or column strength, One Medical Extrusion can custom manufacture braided tubing for you.
Shaft Dimensions
* OD range: 2 French (0.0026”, 0.66mm) through 24 French (0.315”, 8.00mm)
* Wall thickness: 0.005” (0.13mm) – 0.038” (0.97mm)
### Braid Construction
Types:
* 304 Stainless Steel
* 316 Stainless Steel
* Nylon
* Nitinol
Wire Size:
* Round: 0.001” (0.0025mm) – 0.0004” (0.10mm)
* Flat: 0.0005” X 0.0003” (0.013mm X 0.08mm) – 0.002” X 0.007” (0.05mm X 0.18mm)
Braiding patterns:
* Diamond (2 wires under 2 over 2)
* Herringbone (1 wire under 2 over 2)
* Half Diamond (1 wire under 1 over 1)
Braiding cores:
* Directly onto catheter, PTFE, HDPE
* OD: 0.2mm – 8.00mm

* 5 – 250 PPI
## Over-Coating/Over-Jacketing
Extrusion (Over-Coating of Mandrels/ Over-Jacketing of Hypotubes)
In over-coating/over-jacketing, a core mandrel or hypo-tube (which can be a braided component, profiled mandrel, or hypo-tube) is fed through an extruder to coat a layer of thermoplastic polymer.
Our team can provide coatings as thin as 0.001″, depending on the size of the substrate. We can over-jacket laser cut hypo-tube for balloon catheter applications also. Our team works with numerous materials, including but not limited to Polyurethane, Pebax®, and various Blends.We will work with you to determine the ideal over-coating/over-jacketing material for your unique application.
