A mapping processor is configured to receive a current PAT from the input data stream, and to compare input program numbers in the current PAT to known program numbers in the stored format table. If the input program numbers in the current PAT are the same as the input program numbers in the stored format table, then another data stream is output having output program numbers from the stored format table. If the input program numbers in the current PAT are not the same as the input program numbers in the stored format table, then another data stream is output having reassigned output program numbers. The reassigned output program numbers may be from another stored format table in the memory, if the other stored format table has input program numbers that match the input program numbers in the current PAT. If not the reassigned output program numbers may be newly generated. The mapper may also reassign PMT PIDs and / or PIDs within the PMTs.

Devices and methods to deliver, retain and remove a separating device in an intussuscepted hollow organ

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.
