Jacket required: Our flexible Pebax Heat Shrink Tubing is ideal for jacketing laser-cut hypotubes

Interventional device design is trending away from braided shafts towards laser-cut hypotubes. Thanks to cutting technology advances that have ­­reduced cost, it’s now possible to create a thinner, higher-performance device at a cost comparable to traditional methods.

Designing a flexible catheter shaft used to involve a PTFE liner plus braiding plus multiple Pebax® layers. Now, a laser-cut hypotube and a single jacket of Pebax Heat Shrink Tubing can streamline the process. Pebax Heat Shrink Tubing remains on and integrates with the device, eliminating the cumbersome reflow process and reducing manufacturing yield loss.

What makes Pebax so ideal for jacketing laser-cut hypotubes?

1. Flexibility

Unlike other heat shrink tubing, our Pebax Heat Shrink Tubing allows the underlying hypotube to remain flexible.

2. Thin walls

Pebax is super thin, so it does not significantly add to the device profile. Typical wall thickness for a robust jacket ranges from 0.001”—0.003” (0.025 mm—0.075 mm).

3. Strong adhesion

When brought to its shrinking temperature, Pebax Heat Shrink Tubing will thermally bond to an underlying material, whether it’s a metal or a polymer. This also eliminates delamination issues and the need for an adhesive or tie layer.
