Ultra-Thin Wall PTFE Liner for Low-Profile Catheters

The catheter outer diameter is one of the most commercially sensitive specifications in minimally invasive device design. Shaving fractions of a millimeter from a catheter's profile can determine clinical access, patient outcomes, and regulatory pathway. Junkosha's 0.00075-inch wall PTFE Liner achieves this reduction without compromising the lubricity and tensile properties that catheter builders depend on.\n\nAt 0.00075 inches (approximately 19 microns), this liner sits at the practical lower boundary for PTFE liner wall thickness — thin enough to meaningfully reduce catheter OD while thick enough to peel consistently without tearing. The peel-away construction leaves a clean lumen surface with no adhesive residue.\n\nTarget applications include neurovascular microcatheters where access through tortuous intracranial anatomy demands the smallest possible profile, coronary guide catheters where French size directly affects patient tolerance, peripheral vascular delivery systems, and structural heart catheters where sheath OD governs vascular access site selection.\n\nLubricity is maintained through Junkosha's PTFE compound and surface finishing process. Tensile strength meets standard pull-out test requirements for catheter liner applications. The liner is available in the diameters required for the application ranges above.\n\nAvailable in Israel through Koto Electronics.
