Abstract
A catheter including an outer conduit and an inner conduit positioned within the outer conduit, the inner conduit having a smaller diameter that that of the outer conduit. A volume between the outer conduit and the inner conduit define a first lumen which may deliver a first fluid to a patient, and an inside diameter of the inner conduit defines a second lumen which may deliver a second fluid to the patient such that the fluid flow of the first fluid and the second fluid exiting the catheter has a flow profile where the first fluid surrounds the second fluid and the second fluid is prevented from contact with inner walls of a blood vessel of the patient in a vicinity of a tip of the catheter.
