Esteem synergy® Urostomy Pouch. Standard length (10.3"), Accuseal® Tap with valve. The Esteem synergy® ostomy 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, Esteem synergy® 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.
