Abstract

The systems and methods provide effective neuromuscular stimulation to meet a host of different prosthetic or therapeutic objections. The systems and methods also provide convenience of operation, flexibility to meet different user-selected requirements, and transportability and ease of manipulation, that enhance the quality of life of the individual that requires chronic neuromuscular stimulation.

Claims

1. A controller to provide functional neuromuscular stimulation comprising

a housing,

an output device carried by the housing that can be coupled to an electrode,

a first input device carried by the housing to receive a control signal from a first signal source, and

a second input device carried by the housing to receive a control signal from a second signal source different than the first signal source, and

a microprocessor carried by the housing coupled to the output device and the first and second input device including a processing element operative to generate a signal pattern to an electrode to control at least one neuromuscular stimulation function in response to a control signal received from either the first or second input devices.

2. A controller according to claim 1

further including a keypad carried by the housing, and

wherein one of the first and second input devices comprises the keypad.

3. A controller according to claim 2

wherein the other one of the first and second input devices receives the control signal from an element external to the housing.

4. A controller according to claim 1

wherein at least one of the first and second input devices receives the control signal by wireless transmission.

5. A controller according to claim 1

wherein at least one of the first and second input devices receives the control signal by a cable connection.

6. A controller according to claim 1

wherein the processing element operates in a first state to generate the signal pattern in response to a control signal received from first input device and in a second state to generate the signal pattern in response to a control signal received from second input device.

7. A controller according to claim 6

wherein one of the first and second states comprises a default condition for the microprocessor.

11. A method of providing functional neuromuscular stimulation using a controller as defined in claim 1 or 8.

12. A method of providing functional neuromuscular stimulation comprising the steps of providing a controller as defined in claim 1 or 8, and operating the controller to affect at least one motor function.

13. A method of providing functional neuromuscular stimulation comprising the steps of providing a controller as defined in claim 1 or 8, and operating the controller to affect a bladder or bowel control function.

14. A method of providing functional neuromuscular stimulation comprising the steps of providing a controller as defined in claim 1 or 8, and operating the controller to affect an erection control function.

15. A method of providing functional neuromuscular stimulation comprising the steps of providing a controller as defined in claim 1 or 8, and operating the controller to concurrently affect at least one motor function and at least one other neuromuscular stimulation function.

16. A method of providing functional neuromuscular stimulation comprising the steps of providing a controller as defined in claim 1 or 8, and operating the controller to affect at least two neuromuscular stimulation functions.

8. A controller to provide functional neuromuscular stimulation comprising

a housing,

a microprocessor carried by the housing including a processing element operative to generate signal patterns to control neuromuscular stimulation functions,

a first output device carried by the device and coupled to the microprocessor to convey a signal pattern to a first neuromuscular stimulation assembly, and

a second output device carried by the device and coupled to the microprocessor to convey a signal pattern to a second neuromuscular stimulation assembly different than the first neuromuscular stimulation assembly.

9. A controller according to claim 8

wherein the microprocessor enables concurrent selection of conveying a signal pattern to both first and second neuromuscular stimulation assemblies.

10. A controller according to claim 8

wherein the microprocessor enables selection of conveying a signal pattern to either the first or second neuromuscular stimulation assemblies.
