Abstract

An implantable electrical stimulation device configured to treat multiple pelvic conditions of a patient includes a pulse generator, memory, first and second electrode leads comprising one or more electrodes, a switch and a controller. The switch has a first state, in which the first electrode lead is electrically coupled to the pulse generator, and a second state, in which the second electrode lead is electrically coupled to the pulse generator. The controller includes at least one processor that is configured to execute at least one stimulation program stored in the memory. The controller is also configured to selectively set the switch in the first or second state. Electrical stimulation pulses generated by the pulse generator responsive to the execution of the stimulation program are delivered to the first or second electrode lead depending on the state of the switch.

Claims

1-15. -15. (canceled)

16. Implantable electrical stimulation device for treating one or more pelvic conditions comprising:

an implantable control unit comprising;

memory;

at least two stimulation programs stored in the memory;

a controller comprising at least one processor configured to execute at least two stimulation programs stored in the memory; and

at least one pulse generator; and

first and second electrode leads coupled to the control unit, the first and second leads each comprising one or more electrodes;

wherein electrical stimulation pulses generated by the at least one pulse generator are delivered to the first and second electrode leads in response to the execution of the at least two stimulation programs.

17. The device according to claim 16, wherein:

electrical stimulation pulses generated by the at least one pulse generator in response to the execution of a first stimulation program of the at least two stimulation programs are delivered to the first electrode lead; and

electrical stimulation pulses generated by the at least one pulse generator in response to the execution of a second stimulation program of the at least two stimulation programs are delivered to the second electrode lead.

18. The device according to claim 17, wherein:

the stimulation pulses generated by the pulse generator in response to the execution of the first stimulation program are configured to treat a first pelvic condition; and

the stimulation pulses produced by the pulse generator in response to the execution of the second stimulation program are configured to treat a second pelvic condition that is different from the first pelvic condition.

19. The device according to claim 18, wherein the first and second pelvic conditions are selected from the group consisting of urinary incontinence, fecal incontinence, pain due to interstitial cystitis and urine retention.

20. The device according to claim 19, wherein the at least one pulse generator comprises first and second pulse generators, the first pulse generator produces electrical stimulation pulses in response to the execution of the first stimulation program, and the second pulse generator produces electrical stimulation pulses in response to the execution of the second stimulation program.

21. The device according to claim 16, further comprising a switch having a first state in which the first electrode lead is electrically coupled to the at least one pulse generator, and a second state in which the second electrode lead is electrically coupled to the at least one pulse generator, wherein the controller controls the state of the switch.

22. The device according to claim 21, wherein:

the controller sets the switch in the first state and electrical stimulation pulses generated by the pulse generator are delivered to the first electrode lead responsive to the execution of a first stimulation program of the at least two stimulation programs; and

the controller sets the switch in the second state and electrical stimulation pulses generated by the pulse generator are delivered to the second electrode lead responsive to the execution of a second stimulation program of the at least two stimulation programs.

23. The device of claim 22, wherein:

the stimulation pulses generated by the pulse generator in response to the execution of the first stimulation program are configured to treat a first pelvic condition; and

the stimulation pulses produced by the pulse generator in response to the execution of the second stimulation program are configured to treat a second pelvic condition that is different from the first pelvic condition.

24. The device according to claim 23, wherein the first and second pelvic conditions are selected from the group consisting of urinary incontinence, fecal incontinence, pain due to interstitial cystitis and urine retention.

25. A method of treating at least one pelvic conditions of a patient comprising:

implanting an electrical stimulation device in a patient, the electrical stimulation device comprising a control unit, memory, at least one pulse generator, a first electrode lead, and a second electrode lead;

delivering electrical stimulation pulses from the at least one pulse generator through the first electrode lead in response to executing a first stimulation program stored in the memory using at least one processor of the control unit;

delivering electrical stimulation pulses from the at least one pulse generator through the second electrode lead in response to executing a second stimulation program stored in the memory using the at least one processor of the control unit;

treating at least one pelvic condition in response to the delivery of electrical stimulation pulses through the first and second electrode leads.

26. The method according to claim 25, wherein treating at least one pelvic condition comprises treating a first pelvic condition in response to the delivery of electrical stimulation pulses through the first electrode lead.

27. The method according to claim 26, wherein the first pelvic condition is selected from the group consisting of urinary incontinence, fecal incontinence, pain due to interstitial cystitis and urine retention.

28. The method according to claim 26, wherein treating at least one pelvic condition comprises treating a second pelvic condition in response to the delivery of electrical stimulation pulses through the second electrode lead.

29. The method according to claim 28, wherein the second pelvic condition is different than the first pelvic condition.

30. The method according to claim 29, wherein the first and second pelvic conditions are selected from the group consisting of urinary incontinence, fecal incontinence, pain due to interstitial cystitis and urine retention.

31. The method according to claim 30, wherein implanting an electrical stimulation device in a patient comprises:

implanting one or more electrodes of the first electrode lead at a first stimulation site; and

implanting one or more electrodes of the second electrode lead at a second stimulation site that is different from the first stimulation site.

32. The method according to claim 31, wherein the first and second stimulation sites are selected from the group consisting of the urinary sphincter of the patient and the anal sphincter of the patient.
