Abstract:
1. A method for vascular draining using a self-expanding cannula, the method comprising: providing a self-expandable vascular cannula having a length of between about 30 cm and about 70 cm, wherein the cannula includes a low profile conformation for positioning into a blood vessel and a normal profile conformation after positioning, the cannula having an intravascular interior for receiving and draining the entire volume of blood from the blood vessel when the cannula is expanded in the blood vessel; configuring the cannula for positioning within a blood vessel; positioning the cannula in the blood vessel; expanding, subsequent to the positioning within the blood vessel, the cannula to the normal profile conformation such that nearly the entire length of the cannula conforms to the inside wall of the blood vessel; and applying a driving pressure to the cannula thereby initiating blood draining from the blood vessel via the cannula and draining the entire volume of blood from the blood vessel.
