An infusion set (101) includes an inserter (121) pivotally connected to a base (111). The inserter (121) includes a catheter (173) and an introducer needle (167). The catheter (173) is movable from a first catheter position disposed substantially entirely within the inserter (121) to a second catheter position in which a free end of the catheter (173) is disposed externally of the inserter (121) and the base (111). The introducer needle (167) is movable between a first introducer needle position disposed substantially entirely within the inserter (121) and a second introducer needle position in which a free end of the introducer needle (167) is disposed externally of the inserter (121) and the base (111). An activation button (141) is movable between first and second button positions. When the button (141) is moved from the first button position to the second button position, the catheter (173) is moved from the first to the second catheter position, and the introducer needle (167) is moved from the first to the second introducer needle position to facilitate insertion of the catheter (173) and back to the first introducer needle position to store the introducer needle (167) within the inserter (121). The inserter (121) is then pivotable from an insertion position to a storage position within the base (111) of the infusion set (101).
