It is preferred, as shown in FIG. 2, that the splittable bond 180 has a cross sectional width ???w??? at its thinnest point which is a very small fraction of the outer diameter of the multiple catheter assembly 100 to facilitate easy tearing. [0041] The splittable bond 180 is also constructed of a material, such as an adhesive, that will tear before the forces exerted in the outer surfaces of eith
