摘要:
An intragastric implant for obesity treatment is disclosed. The device delays digestion by providing a duodenal sleeve, and may also slows gastric emptying by limiting flow through the pyloric sphincter. The implant includes an elongated axially-compressible duodenal sleeve having a non-tissue-piercing anchor on a proximal end sized to lodge within the duodenal bulb. The anchor may have oppositely-directed anchoring flanges to resists migration in both directions. The sleeve may also have barbed ribs to resist proximal movement back up into the stomach. A method of implant includes collapsing/compressing the device and transorally advancing it through the esophagus to be deployed within the duodenum. A dissolvable jacket may constrain the implant for delivery and naturally dissolve upon implant. Removal of the implant may occur in the reverse.
摘要(中):
公开了一种用于肥胖症治疗的胃内植入物。 该装置通过提供十二指肠套管来延迟消化,并且还可以通过限制通过幽门括约肌的流动来减缓胃排空。 植入物包括细长的可轴向压缩的十二指肠套管,其具有在近端上的非组织穿刺锚固件,其尺寸设置成保持在十二指肠球囊内。 锚固件可以具有相反方向的锚固凸缘以抵抗两个方向上的迁移。 套筒还可以具有倒钩肋,以抵抗近端移动回到胃中。 一种植入物的方法包括塌缩/压缩装置并将其经过食道通过食管进行部署在十二指肠内。 可溶解的护套可以限制植入物用于递送,并且在植入时自然地溶解。 相反,可能会发生植入物的移除。
