Patent ID: 6939316

Claim:
A cranial orthosis for preventing acquired plagiocephaly in infants having a soft developing head area to be protected, comprising: a molded appliance having an interior surface that is conformed in shape to the surface curvature of a human infant cranium and operable to accommodate infant head growth; and two or more layers of soft, flexible material releasably disposed in overlapping nested relation and lining the conformed interior surface of the appliance thereby defining a protective pocket for receiving an infant's head, the protective pocket being sized to provide a close, non-compressive fit about the developing head area to be protected such that when an infant's head is received in the protective pocket and the infant is resting on a sleep surface in a supine position, the infant's head weight forces are spread substantially uniformly across the conformed interior surface facing the developing head area, and whereby the lining layers can be removed one at a time to accommodate head growth.
