Methods and devices are provided for regulating a hydraulic restriction system including a restriction device. In general, the methods and devices can allow for non-invasive, transient pressure control. The methods and devices can also, in some embodiments, mechanically regulate pressure of the restriction device without using any electrical components that may need to be powered to operate over extended periods of time.
1. A method of forming a restriction in a patient, comprising: applying energy to an energy charging mechanism;delivering the energy to an energy storage mechanism which stores the energy; andreleasing the stored energy from the energy storage mechanism to cause fluid to flow from a fluid source int
1. A method of forming a restriction in a patient, comprising: applying energy to an energy charging mechanism;delivering the energy to an energy storage mechanism which stores the energy; andreleasing the stored energy from the energy storage mechanism to cause fluid to flow from a fluid source into a restriction device that is implanted to form a restriction in a pathway;wherein the energy is mechanically applied without using electrical power, the energy is mechanically delivered without using electrical power, and the stored energy is mechanically released without using electrical power;and wherein applying the energy comprises transferring a second fluid from a second fluid source to the energy charging mechanism, the fluid source not being in fluid communication with the second fluid source. 2. The method of claim 1, wherein fluid flow from the fluid source into the restriction device increases an amount of restriction applied to the pathway by the restriction device. 3. The method of claim 1, wherein applying energy comprises applying kinetic energy generated by movement of a patient having the restriction device implanted therein. 4. The method of claim 1, wherein applying energy comprises placing a magnetic device in proximity to the energy charging mechanism. 5. The method of claim 1, wherein energy stored in the energy storage mechanism is released only when the energy charging mechanism is not delivering energy to the energy storage mechanism. 6. The method of claim 1, wherein the energy storage mechanism releases energy to an energy release mechanism that causes a pumping mechanism to pump fluid from the fluid source into the restriction device. 7. The method of claim 1, wherein a pump pumps fluid in a single direction from the fluid source toward the restriction device. 8. The method of claim 1, wherein, when a pressure of fluid in the restriction device is greater than a pre-set pressure limit of a valve coupled to the restriction device, the valve opens to allow fluid to flow out of the restriction device. 9. The method of claim 8, wherein fluid flows out of the restriction device toward the fluid source when a second valve coupled to the restriction device is manually released from a locked position. 10. The method of claim 1, further comprising adjusting a pre-set pressure limit. 11. The method of claim 1, wherein delivering the energy comprises transferring fluid from the energy charging mechanism to the energy storage mechanism, the energy charging mechanism and the energy storage mechanism forming a closed fluid circuit such that the fluid that flows from the fluid source into the restriction device is not included in the closed fluid circuit. 12. The method of claim 1, wherein delivering the energy comprises transferring the second fluid from the energy charging mechanism to the energy storage mechanism. 13. The method of claim 1, wherein releasing the stored energy causes a gear to rotate to pump the fluid from the fluid source into the restriction device. 14. The method of claim 1, wherein the fluid source is not in fluid communication with the energy storage mechanism and the energy charging mechanism such that the fluid in the fluid source that can flow into the restriction device cannot flow into the energy storage mechanism or the energy charging mechanism, and the fluid that can transfer from the energy storage mechanism into the energy charging mechanism and that can transfer from the energy charging mechanism into the energy storage mechanism cannot flow into the restriction device. 15. A method of forming a restriction in a patient, comprising: applying energy to an energy charging mechanism;delivering the energy to an energy storage mechanism which stores the energy; andreleasing the stored energy from the energy storage mechanism to cause fluid to flow from a fluid source into a restriction device that is implanted to form a restriction in a pathway;wherein the energy is mechanically applied without using electrical power, the energy is mechanically delivered without using electrical power, and the stored energy is mechanically released without using electrical power;wherein, when energy is applied to the energy charging mechanism, fluid is transferred from the energy charging mechanism into the energy storage mechanism to deliver the energy to the energy storage mechanism;wherein releasing the stored energy comprises transferring fluid from the energy storage mechanism into the energy charging mechanism to cause the fluid to flow from the fluid source into the restriction device; andwherein the fluid source is in fluid communication with the energy storage mechanism and the energy charging mechanism such that the fluid in the fluid source that can flow into the restriction device can flow into the energy storage mechanism and the energy charging mechanism. 16. The method of claim 15, wherein, when the energy storage mechanism releases the stored energy, fluid is transferred from the energy storage mechanism to the fluid source.
