42. A method of infusing fluid into a body or aspirating fluid from a body comprising:
-
delivering into the body a catheter having a generally elongated catheter body including an exterior surface exposed to the body and an interior surface defining a lumen, the catheter further including an aspiration valve and an infusion valve, wherein at least one of said valves includes a protuberance projecting from the catheter body for permitting one of aspiration or infusion while resisting one of infusion or aspiration, and varying pressure in said lumen to effect infusion or aspiration. - View Dependent Claims (43, 44)
