ABSTRACT:
A catheter system for percutaneous insertion into the lumen of a vessel which includes a hollow introducer needle coaxially mounted within the catheter. Mounted with the introducer needle is a guide wire which is attached to the proximal end of the needle and formed in the shape of a loop of a length sufficient to provide the necessary amount of wire to guide the catheter within the lumen. The catheter has a notched tip to help maintain the tip in the vessel lumen during guide wire placement and to inhibit passing through the opposite wall of the vessel lumen during insertion of the device.
