Abstract
A percutaneous lead is provided which includes a generally tubular, multi-duct, flexible lead body. The lead body supports a distal set of electrodes and a proximal set of contacts which are connected by conductors in the ducts. The lead body further houses an optical fiber with a side firing section. The side firing section is held adjacent an optical transmission window, integrally formed with the flexible lead body. A cylindrical ferrule is provided to position the fiber in the header of an IPG.
Claims24
An implantable pulse generator casing for connection to a set of leads comprising:
- a shell;
- a header, operatively attached to the shell, having a set of parallel lead channels;
- an optical window, positioned in the shell, adjacent the set of parallel lead channels;
- a set of light emitting devices, adjacent the optical window, perpendicular to the set of parallel lead channels;
- a set of light detecting devices, adjacent the optical window, perpendicular to the set of parallel lead channels;
- an optical signal processor, having a memory, operatively connected to the set of light emitting devices and the set of light detecting devices;
- and,
- the memory incorporating a set of instructions that when executed cause the optical signal processor to:
- set a first emitter current on a light emitting device of the set of light emitting devices;
- read an initial detector voltage of a light detecting device of the set of light detecting devices;
- read a steady state detector voltage of the light detecting device of the set of light detecting devices;
- compare the initial detector voltage to the steady state detector voltage;
- and,
- if the steady state detector voltage is less than the initial detector voltage, then increase the first emitter current to a second emitter current.
