e g one opened and then one closed operated simultaneously operated on a delay or a combination thereof for example only one valve may be open at a time in another example one may close and after a time delay another may open the one or more valves may be part of a common fitting located proximate to a common fitting or both the one or more common fittings may function to connect two or more lines into a common line the one or more common fittings may function to connect a suction line and an irrigation line to a common port the one or more common fittings may connect a single line to multiple devices so that multiple devices may be used simultaneously in series in parallel or a combination thereof for example the common fitting may connect a suction line and an irrigation line to a common line that is connected to a sheath and during operation an irrigation fluid may be applied and then after a delay and or immediately when the irrigation fluid ceases to be applied suction may be applied to the suction line so that irrigation fluid excess irrigation fluid debris particles opaque fluids.
