Abstract: A cannula assembly having a hollow elongate cannula with a proximal end, a distal end, and a central axis. A coiled reinforcing member is disposed along a portion of the hollow elongate cannula and is adapted to provide structural support to the elongate cannula. An intermediate reinforcing band is disposed on the elongate cannula between the proximal end and the distal end to reinforce a perforated section in the wall of the cannula and includes a forward edge, a rearward edge, at least one rib and at least one protrusion extending orthogonally from the forward edge and at least one protrusion extending from the rearward edge. A distal reinforcing band is disposed at the distal end of the elongate cannula and has a plurality of fingers that taper slightly inwardly toward the central axis of the hollow elongate cannula.
