Abstract
A medical applicance of a stationary surgical suction device comprised of an ultramalleable formable tube that may readily be shaped in situ. The tube is comprised of a formable, flexible tubular plastic ultramalleable material, having at least one fluid conveying lumen and includes a parallel oriented malleable member that is disposed within the plastic material so as to be frictionally interrelated to the tubular plastic material. A method of fabricating the lumen includes the steps of furnishing a plastic tubing having at least a pair of lumens, furnishing an elongated malleable member of cross-section complementary to that of one of the lumens and of a size in excess of the size of the lumen, dilating the lumen to allow insertion of the malleable member into the lumen and allowing the lumen to shrink onto the malleable member to effect a frictional engagement with the lumen. The applicance fabricated by the method may be used in surgical retracting, suction or irrigation procedures, as a shunt for fluid vessels or for the drainage of a cavity.
