A stationary central dialysis catheter having a planar axially elongated sinuous tubular member having a plurality of axially extending lumens therein and at least a part having a predetermined two-dimensional shape including at least two portions of relative straightness connected by a curved portion region. At least two of said lumens each have at least one aperture for passage of fluid during dialysis, and said apertures are axially displaced from one another along said tubular member. A flexible sheath surrounding at least a part of the tubular member is peelably removable therefrom in situ. Ripcord means is provided in the form of a suture embedded in said flexible sheath and looped around at the distal portion to define a line of weakness separable first adjacent the suture loop for rupturing said sheath in a proximal direction. |
