*2.1.2 ValenTx*

Another novel endoluminal gastro duodenal-jejunal bypass liner which has been introduced is the ValenTx (**Figure 2**) (ValenTx, Inc. Carpinteria, CA, USA) [12]. It is designed to reproduce the restrictive and malabsorptive features of the RYGB, by creating a gastric, duodenal, and biliopancreatic bypass. This gastro duodenaljejunal bypass liner is an implantation device which is delivered endoscopically, but other than the EndoBarrier, requires laparoscopic assistance.
