Leaderflex is a radiopaque polyurethane catheter with fixation wings and integral extension tube 4.4 cm long (except codes 1212.20/205: 9.8 cm long).When it comes with straigth guidewire, Leaderflex is suitable for a variety of venous and arteriel applications in adults and children. The references with a J Nitinol guidewire (1212.062/082) are only indicated for CVC application. Leaderflex, used as Midline, is an alternative to short I.V. cannulae for patients who require intravenous therapy for more than 5 days, improving the quality of patient care: no need for repeated venipunctures with short I.V. cannulae, less risk of chemical and mechanical phlebitis because Leaderflex is made of supple material and can be inserted above the antecubital fossa (improved stabilisation of the catheter, higher blood flow rate in the vessel).
