Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is intended to document procedural and clinical effectiveness in consecutive cases in which at least one MANTIS clip is selected, pertaining to use of a new endoscopic clipping device MANTIS™ including but not limited to hemostasis, closure, anchoring and marking.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To document clinical effectiveness and safety when used per indication within the GI tract for the purpose of:

1. Endoscopic marking
2. Hemostasis for:

* Mucosal/sub-mucosal defects \< 3 cm
* Bleeding ulcers
* Arteries \< 2 mm
* Polyps \< 1.5 cm in diameter
* Diverticula in the colon
* Prophylactic clipping to reduce the risk of delayed bleeding post lesion resection
3. Anchoring to affix jejunal feeding tubes to the wall of the small bowel
4. As a supplementary method, closure of GI tract luminal perforations \< 20 mm that can be treated conservatively
