Flexible double-lumen (FDL) catheter was designed as a temporary blond access (TBA). Silicone rubber is used for the material to enable the patients to walk around freely even if the FDL catheter is inserted through the femoral vein. An inner tube was placed inside of the lumen to insert the catheter using Seldinger's method. The maximum blood flow is more than 300ml/min and V pressure is below 100mmHg under the condition of 200ml/min. A new micropump using two syringes was designed to prevent clotting of the lumens by continuous in-jection of heparin. Clinical application was undertaken in 219 patients and the catheters were used for 1-4 weeks without serious complications FDL catheter is thought superior to external shunt because it can be used as a CVP or infusion line in addition to TBA.
