Claim Text:
1. A method for vascular flow channel placement, the method comprising: (a) advancing a needle through a skin of a patient at an entry point and into a lumen of a vascular flow channel in a first direction; (b) advancing a first wire into a lumen of the needle and into the lumen of the vascular flow channel in the first direction; (c) removing the needle from the lumen of the vascular flow channel and from the skin of the patient; (d) advancing a curved needle over the first wire in the first direction until a tip of the curved needle is in the lumen of the vascular flow channel; (e) removing the first wire from the lumen of the vascular flow channel and from the curved needle; (f) advancing the curved needle in the first direction until the tip of the curved needle exits the lumen of the vascular flow channel and exits through the skin of the patient at an exit point proximal to the entry point; (g) advancing a second wire into and out of a lumen of the curved needle in an air-to-air placement; (h) removing the curved needle completely from the second wire leaving the second wire in the air-to-air placement; (i) advancing a sheath over the second wire in a second direction until an opening of the sheath is within the lumen of the vascular flow channel; (j) retracting a proximal end of the second wire from the sheath until a distal end of the second wire lies within the lumen of the vascular flow channel; and (k) advancing the distal end of the second wire in the second direction within the lumen of the vascular flow channel, enabling further procedures within the vascular flow channel in the second direction.
