    • Generally described herein are automatic, self-adjusting, gastric banding systems and improvements thereof, that are capable of automatically relaxing and contracting in response to a large bolus passing through the area of a patient's stomach constricted by a gastric band. Alternatively, and/or in addition in one or more embodiments, the gastric banding systems described herein may also help prevent pouch dilatation and/or erosion. The apparatus and systems described herein aid in facilitating obesity control and/or treating obesity-related diseases while generally being non-invasive once implanted. Furthermore, certain embodiments of the self-adjusting gastric banding systems disclosed herein are automatically adjustable without complicated fluid control mechanisms, flow rate limiting devices, and/or valves. The automatic adjustments may also be made in response to other changes in the patient's esophageal-gastric junction, for example, in response to size, shape, and or location changes.
    • 一般在此描述的是自动的,自我调节的胃束带系统及其改进,其能够响应于大丸通过胃带收缩的患者胃部区域而自动放松和收缩。 可替代地和/或另外在一个或多个实施例中,本文所述的胃束带系统还可以帮助防止囊扩张和/或侵蚀。 本文所述的装置和系统有助于促进肥胖控制和/或治疗肥胖相关疾病,而一旦植入则通常是非侵入性的。 此外,本文公开的自调节胃束带系统的某些实施例可自动调节而无需复杂的流体控制机构,流量限制装置和/或阀。 例如,响应于患者的食管 - 胃连接处的其他变化,响应于尺寸,形状和/或位置变化,也可以进行自动调整。

    • A self-regulating gastric band apparatus for adjusting stoma size. The apparatus includes an adjustable gastric band that has an inner ring expanding with injected fluid. A band adjustment assembly is provided for implanting with the gastric band that includes a sensor for sensing fluid pressure in the inner ring. The band adjustment assembly further includes a pump assembly connected to the expandable inner ring and to a controller that can operate the pump assembly to adjust the volume of the fluid in the band based on the sensed fluid pressure. The band adjustment assembly includes memory storing an operating range relative to a target fluid pressure, and the pump assembly is operated to maintain the sensed band pressure within the operating range. The target pressure being set to maintain pressure variations below a predefined variation limit generally corresponding with satiated fill volumes for a particular patient and implanted band. An elongated fluid reservoir may extend along a substantial part of a fill tube. A balloon-like expandable fluid reservoir in fluid communication with the pump assembly may store a volume of the fluid for adjusting the volume of fluid in the lumen. A protective outer sheath may be provided around the exterior of an expandable fluid reservoir in both a first, deflated state, and a second, inflated state of the reservoir.
