A dual well port (200) for implantation within a body is proposed. The dual well port comprises a septum (204), a lower housing portion (220) and an upper housing portion (216). The lower housing portion (220) defines first and second wells (206, 208), each of the wells (206, 208) being sealed by the septum (204). The upper housing portion (216) overlies the septum (204) and the lower housing portion (220). The upper housing portion (216) and the lower housing portion (220) are joined to form a leak-proof housing (222).
