Intraspinal Stem Cell Transplantation
This narrated video demonstrates the process of intraspinal microinjection with use of a floating cannula. The cannula is introduced into the cord in rigid confirmation. After the microinjection needle is firmly seated into the spinal cord, the rigid outer cannula is withdrawn. The flexible silastic inner cannula is then able to move with cardioballistic and respiratory-associated cord movement. At microinjection completion, the outer cannula is returned to its original position and the injection cannula is withdrawn.
