Abstract: The invention features compositions and methods for delivering antibodies to the fetal circulation to be used for preventing and/or treating a fetal alloimmune disorder and/or to treat and/or prevent perinatal infections and/or to prevent neonatal necrotizing enterocolitis.

Abstract: The present invention relates to a tracheostomy device with an inflatable balloon (1) attached to a hollow tube (2) by means of two areas of adhesion (1a and 1b) whose ortogonal projections are not contiguous or, in other words, are at an angle (&agr;) other than 180°. This balloon (1) communicates with the environment by means of a capped, valved flexible conduit (4). A movable flange (3) allows for extra fixation of the device around a patient's neck. A displaceable inner tube (5) can be removed in case of severe acute obstruction, allowing for immediate establishment of air flow.
