Esteem synergy with ConvaTec Moldable Technology. The Esteem synergy Ostomy System offers skin barriers with our latest skin barrier technology. ConvaTec Moldable Technology Skin Barriers hug the individual contours of your stoma to allow for a secure, personalized fit without the need for scissors. The Esteem synergyOstomy System utilizes an innovative Adhesive Coupling Technology that connects the pouch to the skin barrier and eliminates the need for plastic rings that must be snapped or locked together. Instead of a plastic ring, Esteemsynergy Pouches feature a flat, flexible adhesive foam ring that securely connects to a flexible, clear landing zone" on the skin barrier. The result is a low-profile, flexible two-piece system.
