Abstract:
1. A intraluminal cannula placement apparatus and specially adapted cannula for placing the cannula into a previously inserted I.V. catheter that has a female Luer connector comprising: a) a cannula having proximal and distal ends; b) a flexible seal attached to the proximal end of the cannula and shaped to engage the interior of the female Luer connector; c) a sheath encasing the cannula and seal and having an interior diameter greater than the outer diameter of the cannula; d) a rod having proximal and distal ends and passing through the seal and extending through the interior of the cannula and having an outer diameter less than the interior diameter of the cannula; e) a slit in the sheath partially extending along the length of the sheath; f) a pusher comprising: g) a modified male Luer coupling at the distal end of the sheath; wherein the modified male Luer coupling lockingly engages the female Luer connector thereby permitting the pusher to engage the seal to advance the cannula into and through the I.V. catheter until the flexible seal compressively engages the interior wall of the female Luer connector thereby securing the cannula in place and preventing leakage.
