Abstract
A medical apparatus which comprises a sharpened outer needle and a blunt inner needle slidingly disposed within the outer needle is provided.

The position indicator may be a mechanical visual indicator, an electronic visual indicator, a tactile indicator, an audible indicator or any combination of the above.
