Cast-film PTFE Catheter Liners Set New Performance Benchmark, Claims ZeusCast-film PTFE Catheter Liners Set New Performance Benchmark, Claims Zeus
A new proprietary cast-film process enables production of the most flexible ultra-thin-walled catheter Zeus has ever manufactured.
January 30, 2025

Medical extruder Zeus has developed a film-cast PTFE catheter liner. It will unveil this newest addition to its Streamliner series of ultra-thin-walled catheter liners at MD&M West in Anaheim, CA, on Feb. 4 to 6, 2025.
A new proprietary film-cast process results in improved consistency, reducing imperfections and pinholes, according to Zeus. This consistency, combined with the expansive sizing and tolerances of existing StreamLiner offerings, is a hallmark of the new ultra-thin StreamLiner NG catheter liner.
Zeus’ PTFE catheter liners are available in wall thicknesses measuring 0.001 in. (0.025 mm) or smaller.
“For years, the Zeus StreamLiner series has set the standard for ultra-thin-walled, high-performance PTFE catheter liners,” noted Zeus Chief Technology Officer Suresh Sainath. “Now, we’re adding to this incredible product portfolio by introducing our first film-cast offering to the PTFE StreamLiner family, one that will raise the bar for what engineers can expect in performance from film-cast liners.”
StreamLiner NG catheter liners are suited for traversing complex vasculatures, such as those found below the knee and above the neck, to deliver critical therapies.
“Given the flexibility film-cast liners provide, engineers prefer them for certain applications but face performance challenges due to surface imperfections and pinholes,” Suresh added. “Our new film-cast liner is the solution. By reducing surface imperfections and pinholes, StreamLiner NG can navigate the most tortuous paths and deliver superior strength and performance, significantly reducing these challenges.”
Zeus is showing the new PTFE catheter liners, which it claims are the most flexible it has ever made, in booth 3001 at MD&M West at the Anaheim Convention Center in Anaheim, CA, from Feb. 4 to 6, 2025.
