which the tubing which serves as the kink resistant member further serves as its fluid supply conduit 0073 fig8 a and 8b show respectively a partial longitudinal cross section and a full radial cross section also seen is the placement of braided tubing terminating in a small plenum 222 just beneath the inflatable member diaphragm 224 the fluid used to inflate the balloon 224 passes through each of these tubing members 220 and conversely to deflate inflatable member 224 along the same path a plenum may be found at the either the distal or the proximal end of the catheter for distribution of fluid to the multiple braided tubing members as was the case above this variation of the first elongate tubular member may include a lubricious inner member 228 or not similarly the materials making up the outer layer 230 may be of the materials discussed above the benefit of this particular design is that it eliminates many layers of parts and yet is able to maintain the inner lumen at a maximum size similarly fig9 shows another variation 240 of catheter walls suitable for use in the inventive balloon catheter in this variation at least one or more rectangular tubing members 242 having open inner lumen is helically placed within the catheter section wall 244 to permit fluid flow to the inflatable balloon the shape of the hollow tubing found in fig8 a 8b and 9 is not limited to those seen in the drawings any convenient shape e g round square rectangular oval etc will suffice 0077 fig1 shows a perspective cut away of catheter section 300 having a plurality of passageways 302 which are used as fluid passage lumen kink resisting member 304 e g a.
