Work with the Catheter ExpertsTM

At Teleflex Medical OEM, our technical expertise in thin-wall, reinforced catheter shafts is among the best in the industry. We are a global leader in terms of tubing profiles and tolerances on the inner and outer diameters of reinforced shafts. In addition, we can meet very high concentricity levels on wall thickness.

Our catheter team has the deep expertise and the integrated capabilities that allow us to successfully take on the large-diameter catheter projects others simply cannot handle. This is due to:

  • Proprietary manufacturing techniques and “trade secret” knowledge developed over the 25+ years.
  • Teleflex Medical OEM’s culture of incremental innovation and asking, “Why not?”
  • Comprehensive, in-house, vertically-integrated capabilities, which include product concept development, engineering, material selection, regulatory services, design for manufacturability, prototyping, manufacturing, and finishing operations.

  • ONE: Market-leading capabilities and tolerances
    • Up to 42F braided sheath, wall thickness as thin as .008” (.2mm)
    • ID tolerances: +/-.002”
    • OD tolerances: +/-.002”
  • TWO: Full range of value-added capabilities
    • Bonding of atraumatic tip sections.
    • Over moulding adds complex geometry to catheter components.
    • Proprietary process of joining shaft segments of dissimilar diameters and reinforcement.

    • Broad range of custom and, in many cases, unique solutions.

Guide to Reinforced, Large-Diameter, Thin-Wall Shafts

Pebax®-lined, large diameter braided shafts

  • Extrusion of very thin, walled sheaths from 12F to 42F.
  • Pebax® can provide high clarity in a range of durometers, and allows ease of bonding in terms of adhesives and overmoulding.
  • The material is a good base material to allow addition of a hydrocoat layer.
  • Pebax® is suitable for Gamma, EtO, and autoclave sterilization.

25F .009”
18F .008”
12F .0075”
Note: Assumes the use of standard .001” by .003” braid wire.

FEP/ETFE-lined, large diameter braided shafts

  • Extrusion of extremely thin-walled sheaths from 12F to 42F. These wall thicknesses are as thin as can be manufactured by any means at the given diameter.
  • FEP is a good low-cost alternative for applications requiring good lubricity.
  • Both FEP and ETFE are made with continuous processes and therefore have a low unit cost point.
  • Good lubricity and chemical resistance.
  • FEP and ETFE are suitable for Gamma, E-beam, EtO, and autoclave sterilization.

HDPE-lined, large diameter braided shafts

  • Extrusion of thin-walled sheaths from 12F to 42F.
  • The material is a good, low-cost alternative for applications requiring good lubricity.
  • Extruded using a continuous process and therefore low unit cost point.
  • HDPE liners are particularly suitable for high density braided designs (ensure very good lamination).
  • Good lubricity and chemical resistance.
  • HDPE can be used in continuous extrusion (like Pebax® or FEP/ETFE).
  • HDPE is suitable for Gamma, E-beam, EtO, and autoclave sterilization.
