Braided Tubing for Medical Applications
Braid reinforced tubing is an extrusion which fully encompasses a metal or fiber braided profile between two layers of polymer. The addition of braided fortification to plastic tubing can drastically expand burst pressure resistance, column strength, and torque transmission.
Braided Catheter Tubing for Medical Applications
Duke’s wire and filament braided tube products and braid reinforced tubing are ideal for catheter shafts and other medical applications that require certain beneficial features, some of these include:
- Torque response
- Axial stiffness
- Kink resistance
- Crush resistance
- Resistance to ovalization
- Electrical shielding
- Higher burst pressure resistance
Braided Tube Options
With our in-house braided tube spooling capabilities, and a large inventory of stock wire and polymer filaments, we can provide lead times as short as one week for our custom braided tubing extrusions. We have numerous options available for our braided catheter tubing, including:
- Multiple ends
- Carriers of 16, 24, or 48
- Variable braid angles
- Dense pics per inch
- Woven braided axial elements
- Flat and round wire ends as small as 0.0005”
- Diameters as small as 0.2 mm, and as large as 17 mm
Additionally, we can also braid single lumens, multi-lumens, eccentric lumens, single- and multi-lumen tapered tubing—we can even add wire braiding to a single lumen within a multi-lumen configuration.
Custom Configurations for Braided Tubing
Using state-of-the-art computer-controlled equipment, Duke Extrusion can control and customize the braid configuration of our wire braiding for optimum effectiveness regarding your medical application. Our advanced, proprietary braiding techniques allow compression loads to be increased, which helps our braided tube avoid buckling during excessive compression loading of retrievable, implantable medical devices such as catheters, stent grafts, and heart valves.
Braided Tube Patterns
Braid patterns are created by controlling the pitch of the filament, the filament gauge size, and filament shape (round, flat, etc.). Examples of patterns for braided tubes include “standard” 1 over 2 under 2, diamond patterns, and 1 over 1 under. Patterns can vary within the length of a single shaft, and increase or decrease the flexibility and stiffness of the braided tubing.
Material Options for Braided Catheter Tubing
There are many unique types of material that can be used to manufacture braid reinforced tubing, some of the more common filaments used include:
- Flat or round metal wire (including stainless steel, nitinol, and others)
- Carbon fiber
Duke Extrusion are experts at selecting the right braiding material and pattern for customers’ needs, and we will work with you to create the ideal solution for your application needs.
