Abstract: A surgical pillow for supporting the heart or other body organs of a patient during surgical operations thereon is formed of an inner body member or filling which is readily deformable by external forces applied to the pillow, as by the patient's organ pressed thereagainst, so as to accommodate itself to the shape of such organ, and which is completely encased within an outer envelope of a thin, flaccid sheet of a synthetic plastic material impervious to air and liquid and non-absorbent of human blood and the outer surface of which is preferably of a character preventing slippage of the body organ thereon without causing irritation or contraction of the supported organ. The inner body member or filling may comprise an aggregate of particulate synthetic plastic foam material such as expanded plastic kernels or beads such as so-called micro-balloons, or it may be formed of soft, spongy, finely cellular material such as sponge rubber or a foamed spongy synthetic plastic such as polyurethane foam.
