Catheter and methods related thereto

A method for vascular insertion of a catheter, the method comprising:

• providing the catheter, the catheter comprising:
• a conduit comprising a distal end configured for vascular insertion and a proximal end;
• wherein the proximal end comprises a straight portion when the conduit is unconstrained;
• wherein the conduit comprises a general U-shaped bend near the distal end of the conduit;
• wherein the conduit further comprises a compound curve disposed between the general U-shaped bend and the distal end;
• wherein a length of the conduit from the straight portion to the compound curve is not tapered;
• wherein the compound curve comprises a first curve and a second curve, the first curve disposed between the U-shaped bend and the second curve;
• wherein the first curve comprises a concave curve such that a distal segment of the first curve extends away from the straight portion of the proximal end;
• wherein the second curve comprises a convex curve such that a distal segment of the second curve extends toward the straight portion of the proximal end;
• wherein the distal end of the conduit is oriented towards the straight portion of the proximal end and away from the general U-shaped bend;
• wherein a length of the conduit distal to the general U-shaped bend is about 5 centimeters to about 15 centimeters;
• wherein a length of the conduit proximal to the general U-shaped bend is sized to extend from a femoral artery to a bifurcation of both common iliac arteries from an aorta artery;
• and
• wherein the conduit further comprises a lumen with an inside diameter;
• disposing the catheter within both common iliac arteries such that the U-shaped bend is disposed at the bifurcation, the distal segment of the first curve extends away from an internal iliac artery, and the distal segment of the second curve extends toward a mouth of the internal iliac artery.
