摘要：
A self-adjusting gastric band comprises an inflatable portion that includes a fluid such as saline. A reservoir is spaced from the inflatable portion according to a distance related to a wavelength of a peristaltic wave that propagates through the esophageal-gastric junction. A pressure-relief valve is coupled between the inflatable portion and the reservoir and allows an amount of the fluid to pass from the inflatable portion to the reservoir when a first force generates an increased pressure in the inflatable portion. The amount of fluid is released to allow the large bolus to pass through the esophageal-gastric junction. A contracted portion of the peristaltic wave is proximate the reservoir when an expanded portion of the wave is proximate the inflatable portion of the self-adjusting gastric band, to facilitate allowing the amount of the fluid to enter the reservoir.
摘要（中）：
自调节胃带包括包括诸如盐水的流体的可充气部分。 根据与通过食道胃结合传播的蠕动波的波长相关的距离，储存器与可充气部分间隔开。 减压阀联接在可膨胀部分和储存器之间，并且当第一力在可充气部分中产生增加的压力时，允许一定量的流体从可充气部分传递到储存器。 释放出的液体量使大量的药丸通过食管胃交界处。 当波的扩展部分靠近自调节胃带的可充气部分时，蠕动波的收缩部分靠近储存器，以便于允许流体进入储存器的量。
