The Filao Over the Wire (OTW) catheter benefits from an all new coating on the sleeve, notably improving its push and torsion. Reliable for angioplasty and predilatation. It has an ultra low and soft penetration, highest level or crossability with minimum vessel wall trauma. Comfortable and reliable manipulation with enhanced uniform push and torsion. Controlled transition from hydrophilic coated proximal to highly flexible distal shaft.
