简要总结
The BaroSense Articulating Circular Endoscopic (ACE) Stapler is an investigational instrument indicated for endoluminal trans-oral tissue approximation and ligation in the gastrointestinal tract. This study explores the specific application of tissue apposition in dilated post-surgical gastric anatomy such as observed in a dilated Roux-en-Y Gastric Bypass (RYGB) pouch.
The primary objective of this study is to perform an evaluation of the safety of the ACE Stapler for the treatment of dilated post-surgical gastric anatomy.
The secondary objective of this study is to evaluate the preliminary efficacy of the ACE Stapler for the treatment of dilated post-surgical gastric anatomy over a 12 month follow-up period.

- •Subject must have a stoma diameter of at least 18 mm.
- •Subject must be fully ambulatory, without chronic reliance on walking aids such as crutches, walkers or a wheelchair.
排除标准
- •Subject has a severe eating disorder.

- •Subject has previously undergone an endoscopic or surgical repair of dilated pouch or stoma (including sclerotherapy treatments).
- •Subject had irreversible or life threatening complications following initial RYGB procedure (cardio or respiratory).
- •Subject has an ongoing severe complication from their initial RYGB procedure (recurrent ventral hernia, pain syndrome, etc.).
- •Subject has an intragastric fistula, anastomotic leak, or staple/suture line disruption.
- •Subject has history of/or signs and/or symptoms of gastro-duodenal ulcer disease.

结局指标
主要结局
Proportion of participants with adverse events
时间窗: Post-procedure through 12 months
The primary safety analysis will assess the occurrence of adverse events through 12 months following procedures. Included in this assessment will be the proportion of subjects with any of the following outcomes between enrollment and completion of the 12 month follow-up evaluation: Adverse Events (AE), Adverse Device Effects (ADE), Serious Adverse Events (SAE) and Unanticipated Adverse Device Effects (UADE).
次要结局
- Percent excess weight loss in participants relative to preop weight(Through 12 months post-procedure)
