1. A device for providing therapy to a patient comprising:
- an implantable portion for implantation in the patient, said implantable portion including a receiver for receiving signals;
an external portion for generating signals, said external portion including a transmitter for transmitting signals to said receiver when said external portion is positioned to provide inductive coupling between said transmitter and said receiver; and
a protective device disposed in said transmitter provided to suppress the effect of electrostatic discharge to prevent propagation of said discharge energy to said implantable portion.
