Abstract
A suction catheter is disclosed having a tubular, bellowed flexible proximal or patient contacting end creating a rigidity to not permit bending and twisting during the catheter's insertion and operation, a flexibility to prevent injuring a patient's trachea or bronchial tube and having a good suction efficiency. A lumen leads to openings in the catheter made at the bellowed proximal end that fluidly connects the lumen with the exterior of the catheter.
