Abstract
Apparatus for depositing a cell product, such as endothelial cell product, in a graft and inserting the graft in a vessel is disclosed. The apparatus preferably comprises a tunneler tube that has a hollow portion for supporting the graft therein, apertures to permit the flow of cell product, and a pointed end cap attached to a distal end of the tunneler tube. The apparatus also has a handle connected to the graft and releaseably connected to a proximal end of the tunneler tube that provides an inlet for cell product and outlet in fluid communication with the lumen of the graft. During deposition, the cell product thus flows through the handle, into the graft and exits through the apertures. During insertion, the tunneler tube is manipulated by the handle to enter a vessel, and is then released from the handle and removed to accommodate anastomoses.
