In Vivo Full-Thickness Endoluminal Gastroplication Using Tissue Anchors in a Live Pig Model

Endoscopic transgastric procedures in anesthetized pigs: technical challenges, complications, and survival

“…Refinements of endoscopic suturing techniques that ensure air− and liquid−tight gastric wall closure are mandatory before embarking on human studies. Three pro− mising new devices that are currently under development are expected to be available soon: the "tissue approximation device" [7,15 ± 17], the Olympus Eagle Claw II [18], and the USGI Medical g−Prox [19]. It is hoped that these will address one of the basic problems in NOTES and therefore will be crucial for the further development of this new surgical approach [20].…”

Endoluminal Methods for Gastrotomy Closure in Natural Orifice TransEnteric Surgery (NOTES)

“…The third new device that will be available in the near future is the g-Prox from USGI Medical. 13 The g-Prox is a novel instrument that combines an aggressive grasper with a needle delivery device that delivers expandable baskets connected by permanent suture. The grasping function was designed to replicate the abilities of a laparoscopic grasper and has similar dimensions (Figure 6A).…”

Safety and Effectiveness of an Endoscopic Suturing Device in a Human Colonic Treat-and-Resect Model

“…These devices range from inexpensive, simple, multipurpose instruments to complex, procedure-specific devices developed to address diseases such as obesity and gastroesophageal reflux. [12][13][14][15][16][17][18][19] Recently, the Overstitch (Apollo Endosurgery, Austin, TX), a device representing 10 years of continued refinement, received US Food and Drug Administration approval for endoscopic suturing applications. 10,16,20 After attachment to the distal end of a standard doublechannel endoscope, the device permits suture placement and tissue approximation under direct endoscopic visualization (Figure 1).…”
