Abstract:
A patient-interactive neurostimulation system, comprising:a plurality of neurological stimulator devices implanted in the body of a patient, said neurological stimulator devices being adapted for receiving a specific one of a plurality of predetermined programming codes and responding thereto to provide electrical stimulation to nervous tissue according to said specific one predetermined programming code; a patient-interactive computer having processing means, said processing means defining which one of said plurality of said specific predetermined programming codes has to be transmitted to said neurological stimulator devices; and a transmitter interface unit operatively coupled to said patient interactive computer and controlled by said processing means to generate either of said plurality of said predetermined programming codes, and to transmit said specific one predetermined code towards said neurological stimulator devices, said transmitter interface unit comprising: a control interface unit communicating with said patient-interactive computer through a communication channel to transmit data defined by said processing means; a data memory unit adapted to store a plurality of parameters for said plurality of said specific predetermined programming codes, said data memory unit interfacing with said control interface unit and exchanging data therewith; a direct digital synthesizer interfacing with said control interface unit for receiving data therefrom and outputting a carrier signal in response thereto; antenna means actuated for transmitting signals corresponding to said predetermined programming codes to said neurological stimulator devices, transistor circuitry operatively coupled to said antenna means for driving said antenna means in an ON/OFF manner, and a driving unit interfacing with said direct digital synthesizer for generating gating pulses supplied to said transistor circuitry to drive same in a manner defined by said processing means within said patient-interactive computer.
