Delamination is a challenging failure mode in catheter construction; it carries both risk and cost burden for device manufacturers. Detection typically does not occur until final testing – after catheter assembly is complete – resulting in significant product loss. Delamination can also lead to failures in the field and product recalls.

By creating a stronger bond between the outer catheter jacket and inner liner, Zeus’ Tie Layer solution increases consistency in catheter performance and ultimately improves patient safety. Tie Layer reduces inspection requirements, increases product yield, and lowers manufacturing costs. Tie Layer is a true total solution in catheter design and manufacturing.

Multiple Options

Tie layers can be used wherever there is a need to bond one surface to another.

Catheter Assembly

Tie layers are a convenient and highly useful option that can be used to enhance bonding of surfaces to the catheter or wire jackets. For catheter components, tie layer options include:

• Tie layer-coated PTFE liners and multi-lumen tubing
• Tie layer-coated FEP liners
• Tie layer-coated polyimide tubing

Tie Layer can also be used to promote adhesion of a coated liner to the ID of a metallic tube. In fact, Tie Layer can be applied to almost any round substrate.

Available Tie Layer Materials Include:

• Pebax® – 35D to 72D durometers
• Vestamid® 75D (Nylons)

Coating thicknesses can be as low as 0.0001″ (0.0025 mm).
