A vascular access port (202) has a housing (210) that includes a base (226) and a cap (228) that capture compound septum (310) to seal each of a pair of distinct fluid reservoirs (250, 252) in the base (226). Distinct target domes (212, 214) of the compound septum (310) are interconnected and encircled by a planar septum web (312) and exposed through respective access apertures (234, 236) in the cap (228). An isolation groove (324) and sealing ridges (326, 328) traverse the lower surface (316) of the septum web (312) between the target domes (212, 214). The outlet stem (222, 370, 390) of the access port (202) is integrally formed with the base (226) of the housing (210). An open fluid channel (262, 264) communicates from each fluid reservoir (250, 252) to a corresponding enclosed fluid passageway (272, 276) in the outlet stem (222, 370, 390) and is closed by a portion (352) of the compound septum (310).
