Abstract
A needle assembly that includes a hub, a cannula and a retractable sheath. The retractable sheath has a tubular portion that initially encases the cannula and is further slideably mounted about a portion of the hub such that the sheath is retractably slidable relative to the hub and along at least the substantial length of the cannula so that (a) at least a substantial portion of the cannula is exposed when the sheath is in its retracted position and (b) a length of the cannula is at least essentially encased when the sheath is in it non-retracted position. In a preferred embodiment, the method of reencasing the cannula after use can be achieved with one hand.
