When I began working on my technique in 1985,I was unaware that Dr.Ichiro Okutsu in Japan and Dr.John Agee in California were both working on similar goals at approximately the same time.Through trial and error of different approaches,a major breakthrough for the development of a slotted cannula came sometime in late 1986.After 4–5 months of persistent practice on cadavers,the procedure was completed in May 1987 and it was first applied to a patient later in September of thesameyear.Afterwards,there were continuous efforts for the improvement of this procedure.
