  • Patent number: 4548602
    Abstract: An intercostal tube designed to be inserted between the ribs of a patient for drainage purposes of the chest area, made of relatively stiff but pliable plastic material with its inserting end at a sharp taper with a blunted end, that by being arcuate, preserves the adequate rigidity to permit the tube to be compressed transversely and inserted between the ribs, without widening the portion of the tube required to pass between the ribs, which would require a larger opening in the patient, and increased pain, and that avoids snagging tissue during insertion.
