Conditions
Summary
The primary objective of this trial is to investigate the safety and effectiveness of the Flexagon SFM system plus OTOLoc when used to create a Ileo-colic and Colo-colonic anastomoses in participants undergoing colon surgery.

Interventions
This study will investigate two types of intervention: ileo-colic and colo-colonic anastomosis creation in subjects undergoing colon surgery. Flexagon SFMs and OTOLoc devices will be delivered laparoscopically and/or endoscopically into a portion of either the ileum or the colon that are intended to be anastomosed. An OTOLoc device will be deployed into the ileum/colon wall to provide access for the deployment of a Flexagon SFM into the bowel. The process is repeated at an intended section of colon. Once deployed, the Flexagon SFMs are approximated and positioned, after which the SFMs are couple together to form the anastomosis, with the OTOLoc devices allowing fluidic communication between the two lumens until the anastomosis is fully formed.
