2% SAE rate (2 of 81) One patient experienced an extra gastric bleed which resolved within one week. No long term sequelae. One patient experienced an intra gastric bleed which required one additional night stay in the hospital. No long-term sequelae.

Satiety Test Data

Mean caloric intake required to reach maximum satiation before the Pose procedure and at 2 and 6 months post-procedure.2

OUS Commercial Data

Commercial weight-loss data demonstrates excellent weight-loss results in a real world clinical setting.

U.S. Clinical Outcomes

The ESSENTIALTM Trial demonstrated statistically significant weight loss and low to moderate risk safety profile of the Pose® procedure. It was the largest blinded endolumenal obesity study ever conducted, with the longest reported follow-up to-date.


The procedure is a safe minimally invasive obesity procedure with one of the lowest serious adverse event (SAE) rates of any endolumenal obesity study. There were no device removals and no device failures.9


People experienced 4x greater weight loss compared to people following a diet and exercise program alone.9 In studies in Europe, on average, over 15% of patients' total body weight was lost after 12 months. This represented 45% of their excess weight.10


Patients maintained 76% of their 12-month weight loss through 24 months (the longest reported follow-up to date among endolumenal obesity studies).11

** USGI Medical has a CE Mark Indication that states: "The design, development and manufacture of preloaded, synthetic, non-absorbable suture delivery catheters (g-Cath) and single use, surgically invasive, flexible endotherapy grasping forceps (g-Lix) used for approximation of soft tissue in minimally invasive gastroenterology procedures, including use in obesity intervention for BMI 30-40.

Those aspects of design, development and manufacture related to securing and mantaining the sterility of non-surgically invasive, multichannel endotherapy guides (Transport) and non-surgically invasive flexible endotherapy grasping forceps (g-Prox)."
