In some examples, a catheter includes a hub assembly, an elongate member, and a plurality of support wires extending along a length of the elongate member. The plurality of support wires is configured to expand radially outward from the elongated body to help anchor a distal portion of the catheter within the vasculature the patient and provide a backup support to the elongate member, e.g., to reduce pushback on the catheter when a treatment device is advanced past the distal tip of the catheter. |
