<p>A cannula structure (40, 100), comprising a cannula (42, 94, 102) having a tubular member (70, 92, 110) secured thereon in surrounding relationship by the exertion of sufficient force by an interior wall of the tubular member on the cannula such that at least one fluid flow path is provided between an exterior wall of the cannula and the interior wall of the tubular member. Preferably, the tubular member is squeezed on opposite sides of the cannula so as to secure the tubular member onto the cannula by crimping.</p> |
