In Frazer v. McGowan, 198 Conn. 243, 248-49, 502 A.2d 905 (1986), a foreign defendant hospital was held to be subject to suit here because of its significant connections with residents of this state other than the plaintiff. Id., at 253-54. The hospital had no structural linkage with Connecticut. It had no treatment facilities here, was not registered here as a foreign corporation and was not licensed to provide medical services here. Id., at 245. Nonetheless, the hospital conferred admitting privileges upon Connecticut physicians, allowed its physicians to maintain Connecticut offices, and provided services to Connecticut patients who made up approximately one third of its clientele. Id., at 253.
