Abstract
A method of anesthetizing a patient includes the steps of providing a plurality of gas permeable tubes, providing means for injecting an anesthetizing gas onto the tubes, inserting the tubes within a blood vessel of a patient and injecting an anesthetizing gas into the tubes so that the gas can diffuse through the tubes into the blood steam to anesthetize the patient. The anesthetizing gas may be an original source of such gas or a vaporizer may be added to a gas line passing to the gas permeable tubes so that oxygen can be passed through the line and a liquid anesthetic vaporized in the vaporizer so that the oxygen carries the vaporized anesthetic into the tubes.
