dont really understand this article! are they using a nerve from a swine(pig) for a donor or are they just using the intercostal nerve? if its the intercostanl nerve, thare has been many members have underwent this procedure an has gotten worse an is formerly known as ICNG that DR. T performs ,..the only thing different is the da vinci device which Dr. Nath uses for nerve grafting!.. very wonderful device , but i would not use or consider nerve graftinf as a feasable approach for repair at all.. i would not touch this procedure with a 50 foot pole! THANKS JIN
