摘要:
A tubular wall, which may be employed in a medical catheter or medical electrical lead, is formed by stranding together a plurality of polymer fibers and at least one metal filar, wherein the stranding forms a braid matrix of the polymer fibers and a coil of the metal filar interlaced therewith. Then, while the braid matrix secures a pitch of the coil, a polymer material is extruded around an entire length of the tubular wall, and, in some cases, the extrusion process causes the plurality of polymer fibers to melt and coalesce together with one another, while the pitch of the coil is maintained. Alternately, a reflow process, which follows extrusion, causes the polymer fibers to melt and coalesce along all, or just a discrete length of the tubular wall.
