Abstract
An embodiment of the invention includes an entry needle. The entry needle may include a cannula, a needle extending within a lumen of the cannula, and a hub operatively associated with a proximal portion of the cannula. The hub may include a branch in communication with the lumen of the cannula. The needle may be movable between a first position and a second position. In the first position, the needle may prevent communication between an opening in an outer wall of the cannula and the branch. In the second position, the needle may allow communication between the opening in the outer wall of the cannula and the branch.
