More Information
Summary:An apparatus for delivery of a vascular arteriovenous graft comprises a tubular sleeve defining an interior lumen adapted for being slidably positioned over a tunneling instrument. Once the tunneling instrument has been advanced to a desired subcutaneous anatomical location the shaft is removed while the sleeve remains in the tissue. The sleeve has a linear slit extending from a proximal end to a point intermediate the length of the sleeve. The lumen receives the distal end of the graft and at least a portion of a cannulation chamber such that the end of the sleeve progressively expands along the slit to provide an enlarged diameter for accommodating the cannulation chamber. Longitudinal force to the sleeve during removal of the sleeve from the tissue secures the graft in the sleeve by radial compression of the sleeve for pulling the graft and the sleeve through the tunnel and deploying the vascular graft.
