Junkosha launched its Clear Peelable Heat Shrink Tubing product this week at the Medical Technology Ireland Show (Sept. 24-25), Europe’s second largest and fastest-growing medical device design and manufacturing event. The company is touting the product as a next-level solution that provides catheter manufacturers with exceptional clarity, reduced assembly risk, and streamlined processes.

During the event, Junkosha explained how the company’s significant expansion in both capacity and manufacturing capabilities has provided customers with increased options in both its Peelable Heat Shrink Tubing and Etched PTFE Liner ranges. 

Between 2021 and 2025, Junkosha has increased production capacity by 300% across its medical device affiliated product portfolio. This includes a doubling of capacity for its Peelable Heat Shrink Tubing and Liner ranges, thanks to investments in new machines and resources. In a sector where both innovation and reliable availability are critical, Junkosha is ensuring its solutions are accessible to customers as they continue to push the boundaries of new interventional products and therapies that improve patient outcomes.

“Over the last few years, we have significantly expanded our capacity, all while keeping open communication at the core of how we work with customers to fulfill their unmet needs,” Junkosha USA Chief Operating Officer Mike Winterling said. “This approach means we are able to build stronger partnerships and ensure expectations are set through our process.”

Junkosha used the Ireland event to showcase its Peelable Heat Shrink Tubing products that support various interventional medical devices. From micro-catheters to larger diameter catheter delivery systems, including structural heart and abdominal aortic aneurism (AAA) repair, all have the key feature of being easy to remove from the catheter during reflow, needing only slits at one end to get it started. This solution reduces the total cost of ownership for catheter manufacturers by eliminating the skiving step, which increases throughput, improves yields and streamlines inspection in a more ergonomically safe process. 

“As minimally invasive procedures are increasingly more sophisticated, catheter features like multi-durometer shafts, braided or coiled reinforcements and laser-cut structures are becoming standard,” Junkosha Global Product Specialist Caroline Herdman explained. “At the same time this added functionality is driving the complexity of devices ever higher. Device manufacturers are utilizing multiple pebax durometers to increase flexibility where it is needed, but also maintain the mechanical performance necessary for a smooth delivery. Junkosha is committed to advancing assembly solutions that meet these evolving needs, leveraging Clear Peelable Heat Shrink Tubing and future innovations to support OEMs and engineering teams.”
