    摘要: Embodiments provide adjustable vascular catheter systems suitable for use in radial access procedures. In embodiments, the adjustable catheter includes an elongated tubular member having a wall defining a proximal end, a distal end, and a main lumen extending therebetween; a first micro-lumen having a proximal end, a distal end, and a hollow lumen extending therebetween, wherein the first micro-lumen extends substantially outwardly from the catheter wall and runs in parallel with the main lumen; and a first shape wire adapted to pass within the first micro-lumen, wherein the first shape wire has a shape memory function sufficient to deflect a deflectable distal portion of the elongated tubular member. In various embodiments, the shape of the deflected distal portion may allow a user to navigate the catheter past one or more tortuosities and reach normally positioned and anomalous positioned vascular ostia. Some embodiments include second and third shape wires, each having a different shape memory function.
