Leading materials specialist addresses increasing demand for larger-diameter delivery systems used in minimally invasive vascular applications at MD&M West

January 29th, 2026 - Junkosha, pioneers of sophisticated fluoropolymer application technologies, is set to launch an expanded range of its Etched PTFE catheter liner portfolio to support the evolving needs of the peripheral vascular market. Building on its established expertise in neurovascular and cardiovascular applications, Junkosha now offers larger sized Etched PTFE liners with inner diameters up to 0.2” (5 mm) to enable the development of larger-profile device delivery systems. Alongside this latest product, Junkosha will feature its thin wall Etched PTFE Liner range with wall thicknesses as thin as 0.00075” (19 µm) and market leading Peelable Heat Shrink Tubing at booth 1867.

The Junkosha® Etched PTFE Liner is widely recognized for its uniform quality, high tensile strength, precise stretch control and reliable mechanical performance in demanding clinical environments. Drawing on over 70 years of expertise in fluoropolymer application technologies, Junkosha has supported device manufacturers with liners featuring inner diameters up to 0.13 inches (3.3 mm), primarily for neurovascular and cardiovascular applications. In recent years, however, the growing adoption of minimally invasive therapies in the peripheral vasculature has driven demand for similar performance characteristics in larger-diameter catheters.

The latest addition to the Etched PTFE Liner range supports the growing use of medical devices for catheter-based treatments for stenosis and occlusion, including drug-coated balloon angioplasty, stent and stent graft deployment, thrombectomy, and atheroma removal. These procedures are commonly used in the treatment of conditions such as Peripheral Arterial Disease (PAD) and Deep Vein Thrombosis (DVT), a trend that is accelerating adoption in both emergency and elective care settings where device reliability and controlled deployment are critical to clinical success.

“In these applications, Etched PTFE liners play a key role within delivery systems, enabling smooth device tracking and the safe, predictable deployment of stents and stent grafts within complex vascular anatomy,” explains Yohei Washiyama, Junkosha’s PTFE Liner Product Specialist. “By extending liner inner diameters to 5 mm, our aim is to support device manufacturers as they design delivery systems for larger vessels, without compromising mechanical integrity or process consistency.”

Washiyama continues: “This latest capability underscores Junkosha’s commitment to meeting customers’ unmet needs through cutting-edge innovations. As minimally invasive, catheter based peripheral vascular procedures continue to expand in scope and complexity, we are focused on advancing liner design, manufacturing precision and size availability to meet increasingly specialized device requirements.”

Alongside larger sized Etched PTFE liners, Junkosha’s thin wall Etched PTFE Liner will also be on show. The thinner liner expands the company’s capabilities, enabling catheter designs with either a larger lumen diameter or a slimmer outer profile, thereby providing greater design freedom for multi-lumen catheters and other complex configurations. Additionally, Junkosha’s full range of Peelable Heat Shrink Tubing products will be on display at MD&M West booth 1867.
