Rotational Localized Drug Delivery Device

摘要

A drug delivery device that uses centrifugal force to deliver a drug to a body lumen wall. The drug delivery device comprises an impeller that includes an impeller shaft; an impeller head at the distal end of the impeller shaft; a drug lumen; an impeller housing; and a housing shaft attached to the impeller housing. In use, the drug is advanced along the drug lumen to the impeller head; at least the impeller head is rotated so that when drug exits the drug lumen, the centrifugal force of the rotating impeller causes the drug to move radially outward from the drug delivery device, towards and into the body lumen wall.
