Patent ID: 8211073

Claim:
An ostomy faceplate comprising a generally annular adhesive wafer of soft, moisture-absorbent, finger-moldable, essentially non-elastic skin barrier material; said wafer having a proximal bodyside surface and an opposite distal surface; said distal surface having an outer zone terminating at an outer periphery of said wafer and a concentric inner zone extending inwardly from said outer zone to a stoma-receiving opening at an inner periphery of said wafer; a flexible backing layer covering said outer zone of said distal surface; and a removable cover member having a smooth surface releasably covering said proximal bodyside surface of said wafer; said distal surface of said inner zone having undulations defined by a series of concentric ridges and valleys with said ridges progressively diminishing in thickness, when measured by the distance between said distal and proximal surfaces at each ridge, as said series progresses inwardly from the maximum thickness of said wafer towards said stoma-receiving opening of said wafer.
