Jerome Jackson, Roger A Stern: Systems for identifying catheters and monitoring their use. EP Technologies, Ryan Kees & Hohenfeldt, January 24, 1995: US05383874 (633 worldwide citation)

A catheter carries a functional component, like an ablating electrode, having a predetermined operating characteristic. The catheter also electronically retains an identification code that uniquely identifies the predetermined operating characteristic. The catheter is capable of transmitting the ide ...
