Abstract
A fluid delivery cannula which provides an interface between an access point or port in the body of a patient and a working channel which may receive tools or instruments used during minimally invasive surgery. The cannula allows introduction of fluid(s) at the port site, or another site within the body of the patient. The fluid delivery cannula can releasably attach to a hub associated with a trocar assembly or may be integrally formed with at least a portion of the hub. In one form, an inner cannula member includes a grooved outer surface to define multiple fluid passages and a perforated outer layer is placed over the inner cannula member. Another form provides an expandable sleeve that may itself comprise a cannula through which a trocar or trocar assembly is inserted or which may take the place of the perforated outer layer of the grooved cannula.
