MANTIS Endoscopic Clipping Study
April 25, 2024 updated by: Boston Scientific Corporation
MANTIS Clip Study: A Prospective, Multi-Center, All-Comer MANTIS Endoscopic Clipping Study:
This study is intended to document clinical effectiveness and safety pertaining to use of a new endoscopic clipping device MANTIS™ when used for hemostasis, closure, anchoring and marking.
Study Overview
Status
Recruiting
Intervention / Treatment
Detailed Description
To document clinical effectiveness and safety when used per indication within the GI tract for the purpose of:
- Endoscopic marking
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
- Anchoring to affix jejunal feeding tubes to the wall of the small bowel
- As a supplementary method, closure of GI tract luminal perforations < 20 mm that can be treated conservatively
