Convexity type refers to the shape of the skin barrier, which can be flat or have a convex curve to help the system fit better against the body. Shallow convexity, as featured in the Marlen 77123 UltraLite Urostomy System, provides gentle pressure to help stomas that are flush or slightly retracted protrude into the pouch, improving the seal and reducing leaks. Shallow convexity is ideal for many users as it balances comfort with effective sealing. The availability of different convexity types allows users to select the best match for their stoma profile.
