Seal-G / Seal-G MIST Study

A prospective, multi-center, open label, study to evaluate safety and performance of Seal-G and Seal-G MIST in reinforcing colonic anastomosis, in subjects undergoing Colon Resection surgery

Seal-G and Seal-G MIST Surgical Sealants are intended for the reinforcement and protection of gastrointestinal anastomosis. The Seal-G and Seal-G MIST devices share the same Alginate based sealant technology and intended purpose. The devices only differ in their method of application, The Seal-G device is designed for spread application by extra-corporal approach, and the Seal-G MIST device is designed for spray application by intra-corporal approach.

The proposed Clinical Investigation aims to collect clinical evidence on the devices' usage, including safety, performance and usability.
