16.5 Detailed analysis of relevant patents

The PATS is a steerable, rigid nasal scope comprising a ring with two concentric holes going
through its diameter; two dumbbell-shaped pins; a tip incorporating four holes and a groove,
connected to said ring via said pins; four wires, in which two connect to the holes in said ring
and passing through the said tip, another two passing through the other two holes in said tip;
and a hollow rigid tube incorporating a complementary groove that fits to said tip.
