Sorry that this reply is five days in coming as I was away from my regular computer
and couldn't get proper access to Investor Village.
The "potential competition" for the daVinci is pretty well summed up in the
following site: http://www.nanalyze.com/2016/07/10-robotic-surgery-companies
As written previously, I continue to believe that competition for ISRG in general surgery will have difficulty gaining traction given ISRG's entrenched position in
hospitals and among surgeons. Furthermore, ISRG's experienced researchers continue
to develop advances in robotic surgery. Of course, no one can predict future
developments but the outlook for continued growth for ISRG is strong.
