The needle is configured to move between a first position and a second position. In its first position, the needle is contained within the housing. In its second position, at least a portion of the needle extends from the housing. The first energy storage member is disposed within the housing, and is configured to produce a first force when actuated. The second energy storage member is disposed within the housing, and is configured to be actuated in response to the first force to produce a second force to move the needle from the first needle position to the second needle position.
