  • Patent number: 5114401
    Abstract: Disclosed are an apparatus and methods for initial, or replacement, central venous catherization using a flexible guidewire with markings thereon and a substantially translucent non-thrombogenic catheter. In operation, the guidewire is inserted along a catheter positioned in a vein. The marks on the guidewire are then used to establish, and maintain as constant, the position of the guidewire. Next, the catheter already in the vein is removed by sliding it over the guidewire, and a new catheter is slipped over the guidewire into position. Once the new catheter is positioned, the guidewire is removed.
