摘要：
The present invention is an improved separating device for providing the malabsorptive component of a minimally invasive weight reduction system. This device may be a sleeve, liner, or tubular sheath that alters absorption of compositions through walls of hollow organs (stomach, intestines). The improvement involves better long-term retention through the ability of the device to engage with the interserosal fibrotic tissue formed in an intussusception. The separating device may be a distal extension of a retaining member that is directly engaged with and retained by intussuscepted tissue. Intussusception shrinks a hollow organ to provide a volume reducing restrictive component of a weight reduction system. Securing the separating device to an intussusception avoids retention problems of reference art devices as interserosal fibrosis helps secure the device. Also provided are an apparatus for retaining the device, a device and method for delivering the separating device, and a method for removing it.
