Abstract:
1. A method for patient tissue preparation, comprising the steps of: providing a manifold having at least one manifold aperture extending therethrough; placing the manifold aperture in fluid communication with a fluid source; providing an insertion structure having a plurality of interior cavities, each interior cavity being at least partially defined by a structure shell, with at least one interior cavity having at least one of a length, width, and cross-sectional shape which is different from at least one of a length, width, and cross-sectional shape of another one of the interior cavities; placing at least a chosen interior cavity in fluid communication with a corresponding manifold aperture; selectively placing the insertion structure in a penetrating relationship with a patient tissue below a surface of the patient tissue; providing at least one shell perforation extending through the structure shell; placing the chosen interior cavity in fluid communication with a surrounding ambient space through at least one shell perforation; when the insertion structure is in the penetrating relationship with the patient tissue, creating at least one fluid path extending from the fluid source, through the manifold aperture, into the chosen interior cavity, through at least one shell perforation, and at least one of a proximate relationship and a contacting relationship with the patient tissue beneath the outer surface thereof; and directing a fluid along the fluid path to perform a patient tissue preparation task.
