Systems for treating an obese patient include one or more sensors configured to sense one or more physical parameters of the patient and one or more implanted stimulators configured to apply a stimulus to the stomach in response to the sensed parameters. Methods of treating an obese patient include sensing one or more physical parameters of the patient and applying a stimulus to the stomach with one or more implanted stimulators in response to the sensed parameters.

What is claimed is: 1. A system for treating an obese patient, said system comprising: a first stimulator configured to be coupled to a first location of a stomach of said patient; and a second stimulator configured to be coupled to a second location of said stomach of said patient; wherein at least one of said first and second stimulators is further configured to sense distension of said stomach by sensing a separation distance between said first and second stimulators; and wherein said at least one of said first and second stimulators is further configured to apply a stimulus to said stomach of said patient in response to said sensed distension of said stomach. 2. The system of claim 1, wherein said first and second locations of said stomach comprise at least one or more of a lesser curvature of said stomach, a greater curvature of said stomach, a wall of said stomach, a cardia of said stomach, a fundus of said stomach, an antrum of said stomach, a pylorus of said stomach, a layer of said stomach, a nerve that innervates said stomach, and a blood vessel that supplies said stomach. 3. The system of claim 1, further comprising: one or more electrode contacts electrically coupled to at least one of said first and second stimulators; wherein said stimulus comprises an electrical stimulation current delivered to said stomach via said electrode contacts. 4. The system of claim 1, wherein said stimulus comprises one or more drugs delivered at said stomach. 5. The system of claim 1, wherein said stimulus comprises an intermittent stimulation. 6. The system of claim 1, wherein said first and second stimulators are coupled directly to a wall of said stomach. 7. The system of claim 1, wherein: said first stimulator is configured to emit a signal having a signal strength; said second stimulator is configured to sense said signal strength; and wherein at least one of said first and second stimulators is configured to determine said separation distance based on said sensed signal strength. 8. The system of claim 7, wherein said second stimulator is configured to sense a change in said signal strength, said change in signal strength corresponding to a change in said distension of said stomach, and wherein said at least one of said first and second stimulators is configured to adjust said stimulus in response to said change in said distension of said stomach. 9. A method of treating an obese patient, said method comprising: coupling a first stimulator to a first location of a stomach of said patient; coupling a second stimulator to a second location of the stomach of said patient; sensing a separation distance between said first and second stimulators to determine a distension of said stomach; and applying a stimulus to said stomach of said patient in response to said sensed distension of said stomach. 10. The method of claim 9, wherein said first and second locations of said stomach comprise at least one or more of a lesser curvature of said stomach, a greater curvature of said stomach, a wall of said stomach, a cardia of said stomach, a fundus of said stomach, an antrum of said stomach, a pylorus of said stomach, a layer of said stomach, a nerve that innervates said stomach, and a blood vessel that supplies said stomach. 11. The method of claim 9, wherein said stimulus comprises an electrical stimulation current delivered to said stomach. 12. The method of claim 9, wherein said stimulus comprises one or more drugs delivered at said stomach. 13. The method of claim 9, wherein said step of applying said stimulus to said stomach comprises intermittently stimulating said stomach in response to said sensed distension of said stomach. 14. The method of claim 9, further comprising coupling a body of at least one of said first and second stimulators directly to a wall of said stomach. 15. The method of claim 9, further comprising: emitting a signal having a signal strength with said first stimulator; sensing said signal strength with said second stimulator; and determining said separation distance based on said sensed signal strength. 16. The method of claim 9, further comprising: sensing a change in said signal strength, said change in signal strength corresponding to a change in said distension of said stomach; and adjusting said stimulus in response to said change in said distension of said stomach. 17. A method comprising: coupling a first stimulator to a first location of a stomach of said patient; coupling a second stimulator to a second location of the stomach of said patient; emitting a signal having a signal strength with said first stimulator; sensing said signal strength with said second stimulator; determining a separation distance based on said sensed signal strength; and applying a stimulus to said stomach of said patient in accordance with said sensed signal strength.
