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; and
releasing 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.

Abstract
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.

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; and releasing 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; and wherein 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. - View Dependent Claims (16)
