ABSTRACT:
An internally carbon coated graft or catheter and method of coating said grafts and catheters through the use of a carbon rod or a metal rod having a carbon pellet at its end coaxially positioned within the substrate's lumen. The graft may be concentrically supported by a metal tube. The rod and metal tube are placed into a vacuum chamber and the rod is subjected to a laser beam to cause the carbon end portion of the rod to transform into gaseous carbon and be deposited on the lumen of the substrate. The process is continued by moving the rod axially along the catheter or graft while being subjected to the effects of the laser beam.
