Convexity refers to the shape of the barrier—flat or convex. Convex barriers are designed to help stomas that are flush, recessed, or difficult to fit, by applying gentle pressure to the peristomal skin and improving the seal. While the Coloplast 12670 and Coloplast 12660 feature flat barriers, there are convex options in the Assura range for those who need them. Having both flat and convex systems available means you can choose what fits and seals best for your unique stoma shape and skin contours.
