Peelable Tubing Technology Could Transform Miniaturized Catheters

- Sep 12, 2018-

The future of the medical tubing industry is an interesting area, not only because organizations in this area face a variety of pressures, but also need to provide cost-effective, high-quality products in less time. This is mainly driven by the global medical market. The global healthcare market continues to demand products and solutions that break through the boundaries at a highly competitive price point.

Take the catheter market as an example. In the world of neurovascular technology, clinicians are working hard to find solutions that enable them to implement complex surgeries more efficiently, thus reducing costs in terms of both time and money, and providing patients with higher quality treatments. . In the next few years, all technologies, including implants, coils, and, in some cases, signaling/treatment through catheters, have changed from "very good" to mainstream.

Development of peelable heat shrinkable tubing

The market for peelable heat shrinkable tubing (PHST) is an exciting area. Not only does it meet the unmet needs of medical customers, it also paves the way for smaller and smaller catheter-based procedures – a continuing need for medical device manufacturers.

The peelable heat shrinking process requires a very specific set of tasks, typically using a mandrel, an etched PTFE liner (EPL), a braided sleeve, a Pebax tube, a PHST, and a laminator. After stretching the EPL liner on the mandrel and knotting it at both ends, the catheter manufacturer should place it in a vertical laminate with a heated chuck on top and a weight on the bottom to ensure continued Heat and stretch. An important consideration for catheter manufacturers at this stage is the tensile strength of the EPL. In general, high tensile strength is desirable, and many manufacturers have specialized processes to develop this strength.

Once the first stage is completed, the etched Teflon-lined mandrel is the first metal braided sleeve of the laminator placed on the lining (this will bend the surgeon to help the catheter around the snake body reach the desired container or partially relieve ) Next is Tube Pebax and finally, PHST. The next stage is to put all of this on the laminate, where the PHST allows all the material to flow back in a continuous, sturdy tube. The catheter manufacturer can easily disengage the PHST, place the mandrel on the neck and pull it out.
