Abstract

Implantable medical device adapted to be implanted in a patient having a plurality of neurological disorders. First and second therapy modules are adapted to provide first and second outputs to the patient for the treatment of first and second of the plurality of disorders, respectively. Also, a method for the treatment of a plurality of neurological disorders in a patient. A first output is provided to the patient for the treatment of a first one of the plurality of neurological disorders and a second output is provided to the patient for the treatment of a second one of the plurality of neurological disorders.

Claims

1. An implantable medical device adapted to be implanted in a patient having a plurality of neurological disorders, comprising:

a first therapy module providing a first output to said patient for the treatment of a first one of said plurality of disorders; and

a second therapy module providing a second output to said patient for the treatment of a second one of said plurality of disorders;

wherein said first therapy module and said second therapy module provide concurrent treatment of said plurality of neurological disorders.

2. An implantable medical device as in claim 1 wherein at least one of said first therapy module and said second therapy module is operative in a closed loop.

3. An implantable medical device as in claim 2 wherein another of said first therapy module and said second therapy module is operable in open loop.

4. An implantable medical device as in claim 2 wherein said at least one of said first output and said second output being a function of another of said first output and said second output.

5. An implantable medical device as in claim 2 further comprising a sensor detecting a sensed event from said patient associated with at least one of said plurality of neurological disorders and wherein at least one of said first therapy module and said second therapy module being operatively coupled to said sensor and being responsive to a sensed event from said patient.

6. An implantable medical device as in claim 1 wherein said first therapy module comprises a drug delivery module and wherein said first output comprises delivery of a medicament.

7. An implantable medical device as in claim 6 wherein said second therapy module comprises an electrical stimulator module and wherein said second output comprises an electrical stimulus signal.

8. An implantable medical device as in claim 7 wherein at least one of said drug delivery module and said electrical stimulator module is operative in a closed loop being responsive to the other of said drug delivery module and said electrical stimulator module.

9. An implantable medical device as in claim 7 further comprising a sensor detecting a sensed event from said patient, wherein at least one of said drug pump module and said electrical stimulator module is operatively coupled to said sensor and responsive to a sensed event from said patient.

10. An implantable medical device as in claim 1 wherein said first output and said second output are delivered based at least in part on cross feedback between said first therapy module and said second therapy module.

11. A method for the treatment of a plurality of neurological disorders in a patient using an implantable medical device having a first therapy module and a second therapy module, comprising the steps of:

providing a first output from said first therapy module to said patient for the treatment of a first one of said plurality of neurological disorders; and

providing a second output from said second therapy module to said patient for the treatment of a second one of said plurality of neurological disorders;

wherein said providing said first output step and providing said second output step provide concurrent treatment of said plurality of neurological disorders.

12. A method as in claim 11 wherein at least one of said first therapy module and said second therapy module is operated in a closed loop.

13. A method as in claim 12 wherein the other of said first therapy module and said second therapy module is operated in open loop.

14. A method as in claim 12 wherein said at least one of said first output and said second output being a function of another of said first output and said second output.

15. A method as in claim 12 further comprising the step of detecting a sensed event from said patient associated with at least one of said plurality of neurological disorders and operating at least one of said first therapy module and said second therapy module responsive to said sensed event.

16. A method as in claim 11 wherein said first therapy module comprises a drug delivery module and wherein said first output comprises delivery of a medicament.

17. A method as in claim 16 wherein said second therapy module comprises an electrical stimulator module and wherein said second output comprises an electrical stimulus signal.

18. A method as in claim 17 wherein at least one of said drug delivery module and said electrical stimulator module is operated in a closed loop being responsive to the other of said drug delivery module and said electrical stimulator module.

19. A method as in claim 17 further comprising the step of detecting a sensed event from said patient and wherein at least one of said drug pump module and said electrical stimulator module is responsive to said sensed event.

20. A method as in claim 11 further comprising the step of implanting said implantable medical device in said patient.

21. A method as in claim 11 wherein said providing said first output step and said providing said second output step occur based at least in part on cross feedback between said first therapy module and said second therapy module.
