About CG-100

In the U.S., Colospan’s CG-100 is an investigational device for patients with colorectal cancer requiring an anastomosis and are to receive a protective stoma under routine clinical practice. The CG-100 Intraluminal Bypass Device is a silicone tubular sheath that is introduced into the colon using a designated delivery system. The protective sheath is held in place by a mechanism that consists of inflatable balloons and an extra-luminal ring that encircles the colon, preventing the sheath from moving downstream while protecting the anastomotic site. After approximately ten days, when the risk for anastomotic leakage is reduced and the anastomosis integrity is confirmed, the sheath and ring are removed without any surgical intervention. The CG-100 Intraluminal Bypass Devices are CE marked (under Medical Device Regulation)in the European Union (EU) and in Israel and  under investigational use (IDE) in the USA.
