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 readily available Pebax heat shrink tubing can streamline the process.
Cobalt Polymers’ Pebax heat shrink tubing is a key component in the design of a new generation of flexible, low-profile interventional devices used for delivery and access in applications including neurovascular, cardiac, and peripheral vascular surgery.
Interventional device design today 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.
Pebax heat shrink tubing is playing a major role in this trend. This flexible, durable, thin-wall heat shrink tubing offers a unique …
