Elongate, flexible catheter includes an elongated shaft having a proximal end, a distal end, and a lumen defined therein. The shaft includes a tubular member having an outer layer and an inner layer. The outer layer includes a first polymer selected from the group consisting of nylon (12), polyether block amide, and combinations thereof. The inner layer includes a second polymer having a heat deflection temperature greater than about 53°C selected from the group consisting of nylon (11), nylon (6), nylon (6,6), nylon (6,12), polyamide-imide, polyetherimide, polypropylene, polyethylene terephthalate, polybutylene terephthalate, polyethereetherketone, and combinations thereof. Method of making an elongate, flexible catheter is also provided. |
