Abstract

System and method of neuromodulation therapy for urinary incontinence disorders comprises a lead to selectively stimulate the sacral plexus and an implantable pulse generator for providing the appropriate pulses. The implantable pulse generator having prepackaged/predetermined programs stored in the memory of the pulse generator, and means for accessing these with an external magnet. The pulse generator adapted to selectively activate predetermined programs with the external magnet, thereby eliminating the need for an external programmer. The elimination of the external programmer resulting in significant cost reduction with essentially the same functionality.

Claims

1. An apparatus for neuromodulation of sacral nerves, comprising:

a) an implantable lead having at least one electrode adapted to be in contact with sacral nerves and connected to a programmerless pulse generator;

b) said programmerless pulse generator comprising circuitry, power source, and at least two predetermined programs to control electrical signals;

c) means to control said at least two predetermined programs by an external magnet,

whereby said implantable pulse generator provides neuromodulation therapy which is controllable by an external magnet.

2. The apparatus of claim 1 wherein said sacral nerves comprises sacral plexus and its branches.

3. The apparatus of claim 1, wherein

a) said electrical signals comprises at least one variable component selected from the group consisting of the current amplitude, pulse width, frequency, on-time and off-time, and;

b) said at least two predetermined programs control the variable component of said electrical signals.

4. The apparatus of claim 1, comprises treatment for one of urinary incontinence, neuro-urological disorders, bladder control, bladder inflammation, and bladder pain such as may be caused by Interstitial cystitis disease or the like.

5. A method of treatment for one of urinary incontinence, neurourological disorders, bladder control, bladder inflammation, bladder pain such as may be caused by Interstitial cystitis disease or the like, comprising:

a) providing a programmerless pulse generator with circuitry, power source, and at least two predetermined programs to control the electrical signals;

b) providing an implanted lead having at least one electrode in contact with sacral nerves and connected to the pulse generator; and

,

c) providing a means for controlling said at least two predetermined programs by an external magnet;

whereby said implanted pulse generator provides neuromodulation therapy which is controllable by an external magnet.

6. The method of claim 5 wherein said sacral nerves comprises sacral plexus and its branches.

7. The method of claim 5, wherein said electric signals comprises at least one variable component selected from the group consisting of the current amplitude, pulse width, frequency, on-time and off-time.

8. The method of claim 5, wherein said at least two of predetermined programs control the variable component of said electrical signals.

9. A method of neuromodulation of sacral nerves comprising:

a) providing a programmerless implantable pulse generator comprising circuitry, power source, at least two predetermined programs to control the electrical signals to said sacral nerves;

b) providing an implantable lead having at least one electrode in contact with said sacral nerves and connected to said pulse generator;

c) activating selectively one of said at least two predetermined programs;

whereby said implanted pulse generator provides neuromodulation therapy to said sacral nerves.

10. The method of claim 9, wherein said pulse generator comprises means to control said predetermined programs with an external magnet.

11. The method of claim 9, wherein said sacral nerves comprises sacral plexus and its branches.
