Abstract: A varied response teether with an outer surface created at least in part by a first elastomeric material and an inner portion including an elastomeric material that has at least one different property than the first elastomeric material.

Abstract: A biologic-response teether (150). The teether (150) has a shield (160) and one or two generally “T”-shaped bite portions (170, 180) projecting from the shield (160). The bite portions (170, 180) each define an elongated stem (171, 181) closest to the shield (160) and two arms (169, 168) that are coupled to and transverse to the stem (171, 181).

Abstract: A feeding teat (40) constructed and arranged to be used on a bottle (52) that holds and dispenses a liquid to be fed to an infant or child. The teat (40) has a nipple portion (70) with an orifice (71) at a terminal end, and defines an interior profile shaped by intersecting reverse curves (75, 76) that generally decrease the interior diameter of the nipple portion (70) toward the orifice (71), so as to channel fluid flow into the orifice (112). There is a flange portion (66) constructed and arranged to be releasably coupled to the bottle (52) such that the liquid can flow from the bottle (52) into the teat (40), and a convexly shaped intermediate portion (80) integrally connecting the nipple portion (70) to the flange portion (66). A pressure relief valve (60) built into the teat (40) is constructed and arranged to admit air into the interior of at least one of the teat (40) and the bottle (52).

Abstract: A nipple appliance having a base portion, a bulb portion having an integrated internal mechanical device that expands as the child sucks on the bulb, and a neck portion connecting the base portion and bulb portion. A sucking force by a child activates the mechanical device by compression of a front of the nipple to redirect force outward and upward by expansion of lateral walls of the bulb, thereby conveying pressure against the palate, alveolar ridge, and/or the teeth.

Abstract: An orthopedic pacifier defining a shield adapted to remain outside of the mouth, a bulb adapted to be located in the mouth and on which the child sucks. The bulb is adapted to expand or move upward and outward as the child sucks on it, to counteract inward pressure of the cheeks and the lateral portion of the lips caused by the suction or sucking action.
