Abstract
A method of inducing retrograde blood flow may include extending a sheath through opposite walls of one of an artery and a vein of a subject and through a wall of the other of the artery and the vein such that a distal end of the sheath may be positioned within one of the artery and the vein. The method may include inducing retrograde blood flow in the artery and delivering the induced retrograde blood flow into the vein of the subject via the sheath.

A method of inducing retrograde blood flow, the method comprising:
- extending a sheath along a straight path through walls of one of an artery and a vein of a subject, and through an adjacent wall of another one of the artery and the vein, such that a portion of the sheath is positioned within the one of the artery and the vein and a distal end of the sheath is positioned within the another one of the artery and the vein;
- inducing retrograde blood flow in the artery;
- and
- delivering the induced retrograde blood flow into the vein of the subject via the sheath.
