Abstract
A reinforced medico-surgical tube comprising a tube of flexible material, a filament helix coaxial with the tube and disposed between inner and outer peripheries of the tube, and a distal end of the tube, the distal end including a straight-cut or angle-cut axial end face disposed at an angle equal to or other than 90.degree. with respect to a central axis of the tube. The filament helix is separated into pieces at the distal end if the tube is angle-cut such that coils of the filament helix are discontinuous with opposite ends of the the coils adjacent the end face of the distal end. The cut filament end in the case of a straight-cut tube or the cut filament ends in the case of an angle-cut tube confront the axial end face and are separated therefrom by a thin layer of flexible material formed by melting the end face, melting a plastic piece onto the end face or by any other suitable method. The end face can be radiused to provide a smooth rounded surface extending between the inner and outer peripheries of the tube at the distal end thereof. One or more eyes can extend between the inner and outer peripheries of the tube at the distal end thereof and one or more secondary lumens can be provided in the tube.
