Abstract
An ostomy appliance having a ring portion and a sheath portion. The ring portion has a first side, a second side and an aperture substantially centered through the first side and the second side. The ring portion also includes a flange extending radially outward from the aperture. A collection pouch can be removably attached to the first side of the ring portion. A generally cylindrically shaped sheath portion has one end securely attached to the ring portion and a second end. The sheath includes a channel configured to accept the body passage through to the aperture on the ring portion. The sheath is made of a nonabsorbable, noncorrosive mesh material which allows the naturally occurring scaring process of the patient to fibrotically attach the sheath to the body passage, and thereby fixedly secure the ring portion to a substantially permanent location on the surface of the patient's body from within the patient's body.
