Microcatheters

You can count on our microcatheters for exceptional torque control, kink and pressure resistance, lubricity, and push-ability.

Choose From a Wide Range of Easily Customizable Configurations

Whether you require PTFE lined, multiple durometer, variable shaft diameter, imbedded marker bands, or thin wall construction, Teleflex Medical OEM should be your outsourcing partner for microcatheters. We have the experience and expertise to meet your rigorous specifications. Our microcatheters are available with flat or round wire, and coil reinforced configurations. Flat wire is generally used for thin-walled applications where "anti-kink" performance is critical. Coiled shafts are more flexible, but they do not have the same torque capabilities as a braided shaft.

Braid Wire Density

Braid wire density is described as picks per inch (PPI), which is the number of wire crossovers per inch of shaft. Depending upon wire and tube sizes, Teleflex Medical OEM can supply up to 250 PPI.

Braid Patterns

  • Regular Braid Pattern – This common pattern uses 16 wires in a one under two, over two pattern.
  • Diamond Braid Pattern - This pattern uses 16 wires but in a two wire under two over two pattern. This pattern tends to provide better torque and more kink resistance than the standard pattern, but the diamond braid has a slightly higher cost.
  • Diamond Braid Pattern, Half Load - By utilizing half the number of wires, the diamond pattern can be produced in a one wire under one, over one pattern. This pattern provides more torque than the regular diamond pattern but incurs a much higher cost due to the reduced wire load.
