A method of manufacturing a catheter, comprising: manufacturing a first medical tubing having a proximal portion, a distal portion, and lumen extending along its length between the proximal portion and the distal portion, the first medical tubing formed of a first material having a first color; manufacturing a second medical tubing having a proximal portion, a distal portion, and a lumen extending along its length between the proximal portion and the distal portion, the second medical tubing formed of a second material having a second color different than the first color; and fixedly securing the second medical tubing to the first medical tubing, wherein the fixedly securing includes: positioning the second medical tubing along the first medical tubing such that the second medical tubing extends parallel to the first medical tubing: heating the material of the first medical tubing; heating the material of the second medical tubing; and applying at least one layer of polymer to the first and second medical tubings (356, 358) such that the at least one layer of polymer bonds with the heated first material of the first medical tubing and bonds with the heated second material of the second medical tubing, wherein the first and second medical tubings (356, 358) are embedded within the at least one layer of polymer as a result of the applying, and wherein the at least one layer of polymer is translucent such that the different first and second colors of the respective first and second medical tubings (356, 358) are visible after the applying. manufacturing a first medical tubing having a proximal portion, a distal portion, and lumen extending along its length between the proximal portion and the distal portion, the first medical tubing formed of a first material having a first color; manufacturing a second medical tubing having a proximal portion, a distal portion, and a lumen extending along its length between the proximal portion and the distal portion, the second medical tubing formed of a second material having a second color different than the first color; and fixedly securing the second medical tubing to the first medical tubing, wherein the fixedly securing includes: positioning the second medical tubing along the first medical tubing such that the second medical tubing extends parallel to the first medical tubing: heating the material of the first medical tubing; heating the material of the second medical tubing; and applying at least one layer of polymer to the first and second medical tubings (356, 358) such that the at least one layer of polymer bonds with the heated first material of the first medical tubing and bonds with the heated second material of the second medical tubing, wherein the first and second medical tubings (356, 358) are embedded within the at least one layer of polymer as a result of the applying, and wherein the at least one layer of polymer is translucent such that the different first and second colors of the respective first and second medical tubings (356, 358) are visible after the applying. heating the material of the first medical tubing; heating the material of the second medical tubing; and applying at least one layer of polymer to the first and second medical tubings (356, 358) such that the at least one layer of polymer bonds with the heated first material of the first medical tubing and bonds with the heated second material of the second medical tubing, wherein the first and second medical tubings (356, 358) are embedded within the at least one layer of polymer as a result of the applying, and wherein the at least one layer of polymer is translucent such that the different first and second colors of the respective first and second medical tubings (356, 358) are visible after the applying.
