Esteem® synergy® Two-Piece Ostomy Systems - Skin Barrier Pouch (Compatible with Esteem synergy® and Esteem synergy®) 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. Esteem synergy® ostomy system is ConvaTec's innovative product that provides the skin friendliness and versatility of a two-piece system, as well as the low profile, comfort, and flexibility of a conventional one-piece system. The Esteem synergy® ostomy system has a flat, flexible adhesive foam ring on the pouch that securely adheres to a clear, flat, flexible plastic "Landing Zone" flange on the skin barrier. The landing zone flange on the skin barrier is square and is slightly larger in size compared to the round adhesive ring on the pouch.
